The SAA7114H is a combination of a two-channel analog preprocessing circuit including source selection, anti-aliasing filter and ADC, an automatic clamp and gain control, a Clock Generation Circuit (CGC), a digital multi-standard decoder containing two-dimensional chrominance/luminance separation by an adaptive comb filter and a high performance scaler, including variable horizontal and vertical up and down scaling and a brightness, contrast and saturation control circuit. • Bi-directional expansion port (X-port) with half duplex functionality (D1), 8-bit YUV – Output from decoder part, real-time and unscaled – Input to scaler part, e.g. video from MPEG decoder (extension to 16-bit possible) • Video image port (I-port) configurable for 8-bit data (extension to 16-bit possible) in master mode (own clock), or slave mode (external clock), with auxiliary timing and hand shake signals It is a highly integrated circuit for desktop video applications. The decoder is based on the principle of line-locked clock decoding and is able to decode the colour of PAL, SECAM and NTSC signals into ITU 601 compatible colour component values. The SAA7114H accepts as analog inputs CVBS or S-video (Y/C) from TV or VCR sources, including weak and distorted signals. An expansion port (X-port) for digital video (bi-directional half duplex, D1 compatible) is also supported to connect to MPEG or video phone codec. At the so called image port (I-port) the SAA7114H supports 8 or 16-bit wide output data with auxiliary reference data for interfacing to VGA controllers. • Discontinuous data streams supported • 32-word × 4-byte FIFO register for video output data • 28-word × 4-byte FIFO register for decoded VBI output data • Scaled 4 : 2 : 2, 4 : 1 : 1, 4 : 2 : 0, 4 : 1 : 0 YUV output • Scaled 8-bit luminance only and raw CVBS data output • Sliced, decoded VBI-data output. 1.6 SAA7114H Miscellaneous • Power-on control The target application for SAA7114H is to capture and scale video images, to be provided as digital video stream through the image port of a VGA controller, for display via VGA’s frame buffer, or for capture to system memory. • 5 V tolerant digital inputs and I/O ports • Software controlled power saving standby modes supported In parallel SAA7114H incorporates also provisions for capturing the serially coded data in the vertical blanking interval (VBI-data). Two principal functions are available: • Programming via serial I2C-bus, full read-back ability by an external controller, bit rate up to 400 kbits/s • Boundary scan test circuit complies with the “IEEE Std. 1149.b1 - 1994”. 1.

In accordance with the “IEEE1149.1” standard the pads TDI, TMS, TCK and TRST are input pads with an internal pull-up transistor and TDO is a 3-state output pad. 2. Pin strapping is done by connecting the pin to supply via a 3.3 kΩ resistor. During the power-up reset sequence the corresponding pins are switched to input mode to read the strapping level. For the default setting no strapping resistor is necessary (internal pull-down). 3. Pin RTCO: operates as I2C-bus slave address pin; RTCO = 0 slave address 42H/43H (default); RTCO = 1 slave address 40H/41H. 4. Pin ALRCLK: 0 = 24.576 MHz crystal (default); 1 = 32.110 MHz crystal. 5. For board design without boundary scan implementation connect the TRST pin to ground. 6. This pin provides easy initialization of the Boundary Scan Test (BST) circuit. TRST can be used to force the Test Access Port (TAP) controller to the TEST_LOGIC_RESET state (normal operation) at once. 2000 Mar 15 9 Philips Semiconductors Preliminary specification 76 VSSD(EP3) SAA7114H 77 TEST3 78 TEST4 79 TEST5 81 XPD7 80 XTRI 82 XPD6 83 VDDD(ICO5) 84 XPD5 85 XPD4 86 XPD3 87 XPD2 88 VSSD(ICO3) 89 XPD1 90 XPD0 91 XRV 92 XRH 93 VDDD(ICO6) 94 XCLK 95 XDQ 96 XRDY 97 TRST 98 TCK handbook, full pagewidth 99 TMS 100 VSSD(EP4) PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler VDDD(EP1) 1 75 VDDD(EP4) TDO 2 74 TEST2 TDI 3 73 TEST1 XTOUT 4 72 HPD0 VSS(XTAL) 5 71 HPD1 XTALO 6 70 HPD2 XTALI 7 69 HPD3 VDD(XTAL) VSSA2 8 68 VDDD(ICO4) 9 67 HPD4 AI24 10 66 HPD5 VDDA2 11 65 HPD6 AI23 12 64 HPD7 SAA7114H AI2D 13 63 VSSD(ICO2) AI22 14 62 IPD0 VSSA1 15 61 IPD1 AI21 16 60 IPD2 VDDA1 17 59 IPD3 AI12 18 58 VDDD(ICO3) AI1D 19 57 IPD4 AI11 20 56 IPD5 AGND 21 55 IPD6 AOUT 22 54 IPD7 VDDA0 23 VSSA0 24 53 IGPH 52 IGPV VDDD(EP2) 25 Fig.2 Pin configuration. 2000 Mar 15 10 VSSD(EP2) 50 IGP1 49 ITRI 47 IGP0 48 IDQ 46 ICLK 45 TEST0 44 VDDD(ICO2) 43 ITRDY 42 AMXCLK 41 ASCLK 39 ALRCLK 40 VSSD(ICO1) 38 AMCLK 37 RTCO 36 RTS1 35 RTS0 34 VDDD(ICO1) 33 SDA 32 SCL 31 RES 30 LLC2 29 LLC 28 CE 27 VSSD(EP1) 26 51 VDDD(EP3) MHB529 This text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here in _white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here inThis text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader. white to force landscape pages to be ...

The characteristics are shown in Fig.3. During the vertical blanking period, gain and clamping control are frozen.

The AGC active time is the sync bottom of the video signal. The clamp control circuit controls the correct clamping of the analog input signals. The coupling capacitor is also used to store and filter the clamping voltage. An internal digital clamp comparator generates the information with respect to clamp-up or clamp-down. The clamping levels for the two ADC channels are fixed for luminance (60) and chrominance (128).

It is controlled by the output signal from the amplitude detection circuit within the burst processing block. The 9-bit CVBS or chrominance input signal is fed to the input of a quadrature demodulator, where it is multiplied by two time-multiplexed subcarrier signals from the subcarrier generation block 1 (0° and 90° phase relationship to the demodulator axis). The frequency is dependent on the chosen colour standard. The burst processing block provides the feedback loop of the chrominance PLL and contains: • Burst gate accumulator The time-multiplexed output signals of the multipliers are low-pass filtered (low-pass 1). Eight characteristics are programmable via LCWB3 to LCWB0 to achieve the desired bandwidth for the colour difference signals (PAL, NTSC) or the 0° and 90° FM signals (SECAM). • Colour identification and killer • Comparison nominal/actual burst amplitude (PAL/NTSC standards only) • Loop filter chrominance gain control (PAL/NTSC standards only) The chrominance low-pass 1 characteristic also influences the grade of cross-luminance reduction during horizontal colour transients (large chrominance bandwidth means strong suppression of cross-luminance). If the Y-comb filter is disabled by YCOMB = 0 the filter influences directly the width of the chrominance notch within the luminance path (large chrominance bandwidth means wide chrominance notch resulting to lower luminance bandwidth). • Loop filter chrominance PLL (only active for PAL/NTSC standards) • PAL/SECAM sequence detection, H/2-switch generation. The increment generation circuit produces the Discrete Time Oscillator (DTO) increment for both subcarrier generation blocks. It contains a division by the increment of the line-locked clock generator to create a stable phase-locked sine signal under all conditions (e.g. for non-standard signals). The low-pass filtered signals are fed to the adaptive comb filter block. The chrominance components are separated from the luminance via a two line vertical stage (four lines for PAL standards) and a decision logic between the filtered and the non-filtered output signals. This block is bypassed for SECAM signals. The comb filter logic can be enabled independently for the succeeding luminance and chrominance processing by YCOMB (subaddress 09H, bit 6) and/or CCOMB (subaddress 0EH, bit 0). It is always bypassed during VBI or raw data lines programmable by the LCRn registers (subaddresses 41H to 57H), see Section 8.2. The PAL delay line block eliminates crosstalk between the chrominance channels in accordance with the PAL standard requirements. For NTSC colour standards the delay line can be used as an additional vertical filter. If desired, it can be switched off by DCVF = 1. It is always disabled during VBI or raw data lines programmable by the LCRn registers (subaddresses 41H to 47H), see Section 8.2. The embedded line delay is also used for SECAM recombination (cross-over switches). The separated UV-components are further processed by a second filter stage (low-pass 2) to modify the chrominance bandwidth without influence to the luminance path. It’s characteristic is controlled by CHBW (subaddress 10H, bit 3). For the complete transfer characteristic of low-passes 1 and 2 see Figs 10 and 11. The SECAM processing (bypassed for QUAM standards) contains the following blocks: • Baseband ‘bell’ filters to reconstruct the amplitude and phase equalized 0° and 90° FM signals • Phase demodulator and differentiator (FM-demodulation) • De-emphasis filter to compensate the pre-emphasized input signal, including frequency offset compensation (DB or DR white carrier values are subtracted from the signal, controlled by the SECAM switch signal). 2000 Mar 15 SAA7114H 19 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler handbook, full pagewidth MHB533 3 V (dB) SAA7114H 0 −3 −6 −9 −12 (1) −15 (2) −18 (3) −21 (4) −24 −27 −30 −33 −36 −39 −42 −45 −48 (1) (2) (3) (4) LCBW[2:0] = 000.

It can be configured as peaking (resolution enhancement) or low-pass block by LUFI3 to LUFI0 (subaddress 09H, bits 3 to 0). The 16 resulting frequency characteristics can be seen in Fig.16. The LUFI3 to LUFI0 settings can be used as a user programmable sharpness control. The rejection of the chrominance components within the 9-bit CVBS or Y input signal is done by subtracting the re-modulated chrominance signal from the CVBS input. The comb filtered UV-components are interpolated (upsampled) by the low-pass 3 block. It’s characteristic is controlled by LUBW (subaddress 09H, bit 4) to modify the width of the chrominance ‘notch’ without influence to the chrominance path. The programmable frequency characteristics available in conjunction with the LCBW2 to LCBW0 settings can be seen in Figs 12 to 15. Note that these frequency curves are only valid for Y-comb disabled filter mode (YCOMB = 0). in comb filter mode the frequency response is flat. The centre frequency of the notch is automatically adapted to the chosen colour standard. The luminance filter block also contains the adjustable Y-delay part; programmable by YDEL2 to YDEL0 (subaddress 11H, bits 2 to 0). The interpolated UV-samples are multiplied by two time-multiplexed subcarrier signals from the subcarrier generation block 2. This second DTO is locked to the first subcarrier generator by an increment delay circuit matched to the processing delay, which is different for PAL and NTSC standards according to the chosen comb filter algorithm. The two modulated signals are finally added to build the re-modulated chrominance signal. 2000 Mar 15 SAA7114H 22 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler handbook, full pagewidth MHB535 3 V (dB) SAA7114H 0 −3 −6 −9 −12 −15 −18 −21 (1) (2) (3) (4) −24 −27 −30 −33 −36 −39 −42 −45 −48 (1) (2) (3) (4) LCBW[2:0] = 000.

It is the multiple of the line frequency: SYNCHRONIZATION The prefiltered luminance signal is fed to the synchronization stage. Its bandwidth is further reduced to 1 MHz in a low-pass filter. The sync pulses are sliced and fed to the phase detectors where they are compared with the sub-divided clock frequency. The resulting output signal is applied to the loop filter to accumulate all phase deviations. Internal signals (e.g. HCL and HSY) are generated in accordance with analog front-end requirements. The loop filter signal drives an oscillator to generate the line frequency control signal LFCO, see Fig.19. 6.75 MHz = 429 × fH (50 Hz), or 6.75 MHz = 432 × fH (60 Hz). Internally the LFCO signal is multiplied by a factor of 2 and 4 in the PLL circuit (including phase detector, loop filtering, VCO and frequency divider) to obtain the output clock signals. The rectangular output clocks have a 50% duty factor. Table 2 The detection of ‘pseudo syncs’ as part of the macrovision copy protection standard is also done within the synchronization circuit.

After the rising edge of CE and sufficient power supply voltage, the outputs LLC, LLC2 and SDA return from 3-state to active, while the other signals have to be activated via programming. A missing clock, insufficient digital or analog VDDA0 supply voltages (below 2.7 V) will start the reset sequence; all outputs are forced to 3-state (see Fig.20).

LCR2 to LCR23 refer to line numbers. The selection in LCR24 values is valid for the rest of the corresponding field. The upper nibble contains the value for field 1 (odd), the lower nibble for field 2 (even). The relationship between LCR values and line numbers can be adjusted via VOFF8 to VOFF0, located in subaddresses 5BH (bit 4) and 5AH (bits 7 to 0) and FOFF subaddress 5BH (bit D7). The recommended values are VOFF[8:0] = 03H for 50 Hz sources (with FOFF = 0) and VOFF[8:0] = 06H for 60 Hz sources (with FOFF = 1), to accommodate line number conventions as used for PAL, SECAM and NTSC standards; see Tables 4 to 7. The output interface block of the decoder part contains the ITU 656 formatter for the expansion port data output XPD7 to XPD0 (for a detailed description see Section 9.4.1) and the control circuit for the signals needed for the internal paths to the scaler and data slicer part. It also controls the selection of the reference signals for the RT port (RTCO, RTS0 and RTS1) and the expansion port (XRH, XRV and XDQ). The generation of the decoder data type control signals SET_RAW and SET VBI is also done within this block. These signals are decoded from the requested data type for the scaler input and/or the data slicer, selectable by the control registers LCR2 to LCR24 (see also Chapter 15 “I2C-bus description”, subaddresses 41H to 57H).

With a safety margin of 2% for running in and running out, the maximum HV_zoom is equal to: T_input_field – T_v_blanking 0.98 × -------------------------------------------------------------------------------------------------------------------------------------in_pixel × in_lines × out_cycle_per_pix × T_out_clk The High Performance video Scaler (HPS) is based on the system as implemented in SAA7140, but enhanced in some aspects. Vertical upsampling is supported and the processing pipeline buffer capacity is enhanced, to allow more flexible video stream timing at the image port, discontinuous transfers, and handshake. The internal data flow from block to block is discontinuous dynamically, due to the scaling process itself. For example: 1. Input from decoder: 50 Hz, 720 pixel, 288 lines, 16-bit data at 13.5 MHz data rate, 1 cycle per pixel; output: 8-bit data at 27 MHz, 2 cycles per pixel; the maximum HV_zoom is equal to: 20 ms – 24 × 64 µs 0.98 × -------------------------------------------------------- = 1.18 720 × 288 × 2 × 37 ns The flow is controlled by internal data valid and data request flags (internal handshake signalling) between the sub-blocks. Therefore the entire scaler acts as a pipeline buffer. Depending on the actually programmed scaling parameters the effective buffer can exceed to an entire line. The access/bandwidth requirements to the VGA frame buffer are reduced significantly. 2. Input from X-port: 60 Hz, 720 pixel, 240 lines, 8-bit data at 27 MHz data rate (ITU 656), 2 cycles per pixel; output via I + H-port: 16-bit data at 27 MHz clock, 1 cycle per pixel; the maximum HV_zoom is equal to: 16.666 ms – 22 × 64 µs 0.98 × -------------------------------------------------------------- = 2.34 720 × 240 × 1 × 37 ns The high performance video scaler in SAA7114H has the following major blocks. • Acquisition control (horizontal and vertical timer) and task handling (the region/field/frame based processing) • Prescaler, for horizontal down-scaling by an integer factor, combined with appropriate band limiting filters, especially anti-aliasing for CIF format The video scaler receives its input signal from the video decoder or from the expansion port (X-port). It gets 16-bit YUV 4 : 2 : 2 input data at a continuous rate of 13.5 MHz from the decoder. Discontinuous data stream can be accepted from the expansion port (X-port), normally 8-bit wide ITU 656 like YUV data, accompanied by a pixel qualifier on XDQ. • Brightness, saturation, contrast control for scaled output data • Line buffer, with asynchronous read and write, to support vertical up-scaling (e.g. for videophone application, converting 240 into 288 lines, YUV 4 : 2 : 2) The input data stream is sorted into two data paths, one for luminance (or raw samples), and one for time multiplexed chrominance U and V samples. An YUV 4 : 1 : 1 input format is converted to 4 : 2 : 2 for the horizontal prescaling and vertical filter scaling operation. • Vertical scaling, with phase accurate Linear Phase Interpolation (LPI) for zoom and down-scale, or phase accurate Accumulation Mode (ACM) for large down-scaling ratios and better alias suppression • Variable Phase Delay (VPD), operates as horizontal phase accurate interpolation for arbitrary non-integer scaling ratios, supporting conversion between square (SQR) and rectangular (CCIR) pixel sampling The scaler operation is defined by two programming pages A and B, representing two different tasks, that can be applied field alternating or to define two regions in a field (e.g. with different scaling range, factors, and signal source during odd and even fields). • Output formatter for scaled YUV 4 : 2 : 2, YUV 4 : 1 : 1 and Y only (format also for raw data) Each programming page contains control: • FIFO, 32-bit wide, with 64 pixel capacity in YUV formats • For signal source selection and formats • Output interface, 8 or 16 (only if extended by H-port) data pins wide, synchronous or asynchronous operation, with stream events on discrete pins, or coded in the data stream. 2000 Mar 15 SAA7114H • For task handling and trigger conditions • For input and output acquisition window definition • For H-prescaler, V-scaler and H-phase scaling. 37 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler Raw VBI-data will be handled as specific input format and need an own programming page (= own task). (XD11 to XD0, YD11 to YD0) closes the window, but the window is cut vertically, if there are less output lines than expected. The trigger events for the pixel and line counts are the horizontal and vertical reference edges as defined in subaddress 92H. In VBI pass through operation the processing of prescaler and vertical scaling has to be set to no-processing, but the horizontal fine scaling VPD can be activated. Upscaling (oversampling, zooming), free of frequency folding, up to factor 3.5 can be achieved, as required by some software data slicing algorithms. The task handling is controlled by subaddress 90H (see Section 8.3.1.2). 8.3.1.1 These raw samples are transported through the image port as valid data and can be output as Y only format. The lines are framed by SAV and EAV codes. 8.3.1 SAA7114H Input field processing The trigger event for the field sequence detection from external signals (X-port) are defined in subaddress 92H. From the X-port the state of the scalers H-reference signal at the time of the V-reference edge is taken as field sequence identifier FID. For example, if the falling edge of the XRV input signal is the reference and the state of XRH input is logic 0 at that time, the detected field ID is logic 0. ACQUISITION CONTROL AND TASK HANDLING (SUBADDRESSES 80H, 90H, 94H TO 9FH AND C4H TO CFH) The acquisition control receives horizontal and vertical synchronization signals from the decoder section or from the X-port. The acquisition window is generated via pixel and line counters at the appropriate places in the data path. From X-port only qualified pixels and lines (= lines with qualified pixel) are counted. The bits XFDV[92H[7]] and XFDH[92H[6]] are defining the detection event and state of the flag from the X-port. For the default setting of XFDV and XFDH at ‘00’ the state of the H-input at the falling edge of the V-input is taken. The acquisition window parameters are: The scaler directly gets a corresponding field ID information from the SAA7114H decoder path. • Signal source selection regarding input video stream and formats from the decoder, or from X-port (programming bits SCSRC[1:0]91H[5:4] and FSC[2:0]91H[2:0]) The FID flag is used to determine, whether the first or second field of a frame is going to be processed within the scaler and it is used as trigger condition for the task handling (see bits STRC[1:0]90H[1:0]). Remark: The input of raw VBI-data from internal decoder should be controlled via the decoder output formatter and the LCR registers (see Section 8.2 “Decoder output formatter”) According to ITU 656, FID at logic 0 means first field of a frame. To ease the application, the polarities of the detection results on the X-port signals and the internal decoder ID can be changed via XFDH. • Vertical offset defined in lines of the video source, parameter YO[11:0]99H[3:0]98H[7:0] As the V-sync from the decoder path has a half line timing (due to the interlaced video signal), but the scaler processing only knows about full lines, during 1st fields from the decoder the line count of the scaler possibly shifts by one line, compared to the 2nd field. This can be compensated by switching the V-trigger event, as defined by XDV0, to the opposite V-sync edge or by using the vertical scalers phase offsets. The vertical timing of the decoder can be seen in Figs 21 and 22. • Vertical length defined in lines of the video source, parameter YS[11:0]9BH[11:8]9AH[7:0] • Vertical length defined in number of target lines, as result of vertical scaling, parameter YD[11:0]9FH[11:8]9EH[7:0] • Horizontal offset defined in number of pixels of the video source, parameter XO[11:0]95H[3:0]94H[7:0] • Horizontal length defined in number of pixels of the video source, parameter XS[11:0]97H[3:0]96H[7:0] As the H and V reference events inside the ITU 656 data stream (from X-port) and the real-time reference signals from the decoder path are processed differently, the trigger events for the input acquisition also have to be programmed differently. • Horizontal destination size, defined in target pixels after fine scaling, parameter XD[11:0]9DH[3:0]9CH[7:0]. The source start offset (XO11 to XO0, YO11 to YO0) opens the acquisition window, and the target size 2000 Mar 15 38 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler Table 8 SAA7114H Processing trigger and start DESCRIPTION XDV1 92H[5] XDV0 92H[4] XDH 92H[2] 0 1 0 Internal decoder: The processing triggers at the falling edge of the V123 pulse (see Figs 21 (50 Hz) and 22 (60 Hz)), and starts earliest with the rising edge of the decoder HREF at line number: 4/7 (50/60 Hz, 1st field), respectively 3/6 (50/60 Hz, 2nd field) (decoder count) 2/5 (50/60 Hz, 1st field), respectively 2/5 (50/60 Hz, 2nd field) (decoder count) External ITU 656 stream: The processing starts earliest with SAV at line number 23 (50 Hz system), respectively line 20 (60 Hz system) (according ITU 656 count) 8.3.1.2 Task handling 0 0 0 0 Remarks: • To activate a task the start condition must be fulfilled and the acquisition window offsets must be reached. For example, in case of ‘start immediately’, and two regions are defined for one field, the offset of the lower region must be greater than (offset + length) of upper region, if not, the actual counted H and V position at the end of the upper task is beyond the programmed offsets and the processing will ‘wait for next V’. The task handler controls the switching between the two programming register sets. It is controlled by subaddresses 90H and C0H. A task is enabled via the global control bits TEA[80H[4]] and TEB[80H[5]]. The handler is then triggered by events, which can be defined for each register set. In case of a programming error the task handling and the complete scaler can be reset to the initial states by the software reset bit SWRST[88H[5]] at logic 0. • Basically the trigger conditions are checked, when a task is activated. It is important to realize, that they are not checked, while a task is inactive. So you can not trigger to next logic 0 or logic 1 with overlapping offset and active video ranges between the tasks (e.g. task A STRC[2:0] = 2, YO[11:0] = 310 and task B STRC[2:0] = 3, YO[11:0] = 310 results in output field rate of 50⁄3 Hz). Especially if the programming registers, related acquisition window and scale are reprogrammed, while a task is active, a software reset must be done after programming. Contrary to the disabling/enabling of a task, which is evaluated at the end of a running task, SWRST at logic 0 sets the internal state machines directly to their idle states. • After power-on or software reset (via SWRST[88H[5]]) task B gets priority over task A. The start condition for the handler is defined by bits STRC[1:0]90H[1:0] and means: start immediately, wait for next V-sync, next FID at logic 0 or next FID at logic 1. The FID is evaluated, if the vertical and horizontal offsets are reached. With RPTSK[90H[2]] at logic 1 the actual running task is repeated (under the defined trigger conditions), before handing control over to the alternate task. To support field rate reduction, the handler is also enabled to skip fields (bits FSKP[2:0]90H[5:3]) before executing the task. A TOGGLE flag is generated (used for the correct output field processing), which changes state at the beginning of a task, every time a task is activated. Examples can be seen in Section 8.3.1.3. 2000 Mar 15 0 0 39 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler 8.3.1.3 Output field processing When OFIDC[90H[6]] = 1, the TOGGLE information is available as output field ID on bit D6 of SAV and EAV, respectively on pin IGP0 (IGP1), if FID output is selected. As reference for the output field processing, two signals are available for the back-end hardware. Additionally the bit D7 of SAV and EAV can be defined via CONLH[90H[7]]. CONLH[90H[7]] = 0 (default) sets D7 to logic 1, a logic 1 inverts the SAV/EAV bit D7. So it’s possible to mark the output of the both tasks by different SAV/EAV codes. This bit can also be seen as ‘task flag’ on the pins IGP0 (IGP1), if TASK output is selected. These signals are the input field ID from the scaler source and a TOOGLE flag, which shows, that an active task is used an odd (1, 3, 5...) or even (2, 4, 6...) number of times. Using a single or both tasks and reducing the field or frame rate with the task handling functionality, the TOGGLE information can be used, to reconstruct an interlaced scaled picture at a reduced frame rate. The TOGGLE flag isn’t synchronized to the input field detection, as it is only dependent on the interpretation of this information by the external hardware, whether the output of the scaler is processed correctly (see Section 8.3.3). With OFIDC = 0, the scalers input field ID is available as output field ID on bit D6 of SAV and EAV, respectively on pin IGP0 (IGP1), if FID output is selected. 2000 Mar 15 SAA7114H 40 This text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here in _white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here inThis text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader. white to force landscape pages to be ...

Philips Semiconductors Examples for field processing PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler 2000 Mar 15 Table 9 Preliminary specification SAA7114H Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler 8.3.2 • The bit XC2_1[A2H[3]], which defines the weighting of the incoming pixels during the averaging process HORIZONTAL SCALING The overall horizontal required scaling factor has to be split into a binary and a rational value according to the equation: output pixel H-scale ratio = -----------------------------input pixel – XC2_1 = 0 ⇒ 1 + 1...+ 1 +1 – XC2_1 = 1 ⇒ 1 + 2...+ 2 +1 The prescaler builds a prescale dependent FIR low-pass, with up to (64 + 7) filter taps. The parameter XACL[5:0] can be used to vary the low-pass characteristic for a given integer prescale of 1⁄XPSC[5:0]. The user can therewith decide between signal bandwidth (= sharpness impression) and alias. 1 1024 H-scale ratio = ---------------------------- × ------------------------------XPSC[5:0] XSCY[12:0] where, parameter of prescaler XPSC[5:0] = 1 to 63 and parameter of VPD phase interpolation XSCY[12:0] = 300 to 8191 (0 to 299 are only theoretical values). For example, 1⁄3.5 is to split in 1⁄4 × 1.14286. The binary factor is processed by the prescaler, the arbitrary non-integer ratios is achieved via the variable phase delay VPD circuitry, called horizontal fine scaling. Latter calculates horizontally interpolated new samples with a 6-bit phase accuracy, which relates to less than 1 ns jitter for regular sampling scheme. Prescaler and fine scaler are building the horizontal scaler of the SAA7114H. Equation for XPSC[5:0] calculation is: Npix_in XPSC[5:0] = lower integer of ----------------------Npix_out where, the range is 1 to 63 (value 0 is not allowed!); Npix_in = number of input pixel, and Npix_out = number of desired output pixel over the complete horizontal scaler. Using the accumulation length function of the prescaler (XACL[5:0]A1H[5:0]), application and destination dependent (e.g. scale for display or for a compression machine), a compromise between visible bandwidth and alias suppression can be found. 8.3.2.1 SAA7114H The use of the prescaler results in a XACL[5:0] and XC2_1 dependent gain amplification. The amplification can be calculated according to the equation: DC gain = ((XACL − XC2_1) + 1) × (XC2_1 + 1) It is recommended to use sequence lengths and weights, which results in a 2N DC gain amplification, as these amplitudes can be renormalized by the XDCG[2:0] 1 controlled -----shifter of the prescaler. N 2 Horizontal prescaler (subaddresses A0H to A7H and D0H to D7H) The prescaling function consists of an FIR anti-alias filter stage and an integer prescaler, which is building an adaptive prescale dependent low-pass filter, to balance sharpness and aliasing effects. The renormalization range of XDCG[2:0] is 1, 1⁄2... down to 1⁄ 128. The FIR prefilter stage implements different low-pass characteristics to reduce alias for down-scales in the range of 1 to 1⁄2. A CIF optimized filter is build in, which reduces artefacts for CIF output formats (to be used in combination with the prescaler set to 1⁄2 scale). See Table 10. • An integer prescaling ratio XPSC[5:0]A0H[5:0] (= 1 to 63), which covers the integer down-scale range 1 to 1⁄63 Other amplifications have to be normalized by using the following BCS control circuitry. In these cases the prescaler has to be set to an overall gain ≤1, e.g. for an accumulation sequence of ‘1 + 1 + 1’ (XACL[5:0] = 2 and XC2_1 = 0), XDCG[2:0] must be set to ‘010’, equals 1⁄4 and the BCS has to amplify the signal to 4⁄3 (SATN[7:0] and CONT[7:0] value = lower integer of 4⁄ × 64). 3 • An averaging sequence length XACL[5:0]A1H[5:0] (= 0 to 63); range 1 to 64 The use of XACL[5:0] is XPSC[5:0] dependent. XACL[5:0] must be ≤2 × XPSC[5:0]. • A DC gain renormalization XDCG[2:0]A2H[2:0]; 1 down to 1⁄128 XACL[5:0] can be used to find a compromise between bandwidth (= sharpness) and alias effects. The functionality of the prescaler is defined by: 2000 Mar 15 42 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler SAA7114H Where: Remark: Due to bandwidth considerations XPSC[5:0] and XACL[5:0] can be chosen different to the previous mentioned equations or Table 11, as the H-phase scaling is able to scale in the range from zooming up by factor 3 to down-scale by a factor of 1024⁄8191. 2XDCG[2:0] ≥ DC gain DC gain = (XC2_1 + 1) × XACL[5:0] + (1 − XC2_1). For example, if XACL[5:0] = 5, XC2_1 = 1, then DC gain = 10 and the required XDCG[2:0] = 4. Figs 26 and 27 show some resulting frequency characteristics of the prescaler. The horizontal source acquisition timing and the prescaling ratio is identical for both luminance path and chrominance path, but the FIR filter settings can be defined differently in the two channels. Table 11 shows the recommended prescaler programming. Other programmings, than documented in Table 11, may result in better alias suppression, but the resulting DC gain amplification needs to be compensated by the BCS control, according to the equation: Fade-in and fade-out of the filters is achieved by copying an original source sample each as first and last pixel after prescaling. XDG[2:0] 2 CONT[7:0] = SATN[7:0] = lower integer of ---------------------------------DC gain × 64 Figs 24 and 25 show the frequency characteristics of the selectable FIR filters.

Resulting FIR function. 2000 Mar 15 46 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler 8.3.2.2 Horizontal fine scaling (variable phase delay filter; subaddresses A8H to AFH and D8H to DFH) 8.3.3.1 The line buffer can buffer a complete unscaled active video line or more than one shorter lines (only for non-mirror mode), for selective repetition for vertical zoom-up. In combination with the prescaler a compromise between sharpness impression and alias can be found, which is signal source and application dependent. For zooming up 240 lines to 288 lines e.g., every fourth line is requested (read) twice from the vertical scaling circuitry for calculation. For the luminance channel a filter structure with 10 taps is implemented, for the chrominance a filter with 4 taps. For conversion of a 4 : 2 : 0 or 4 : 1 : 0 input sampling scheme (MPEG, video phone, video YUV-9) to CCIR like sampling scheme 4 : 2 : 2, the chrominance line buffer is read twice of four times, before being refilled again by the source. By means of the input acquisition window definition it has to be preserved, that the processing starts with a line containing luminance and chrominance information for 4 : 2 : 0 and 4 : 1 : 0 input. The bits FSC[2:1]91H[2:1] are defining the distance between the Y/C lines. In case of 4 : 2 : 2 and 4 : 1 : 1 FSC2 to FSC1 have to be set to ‘00’. Luminance and chrominance scale increments (XSCY[12:0]A9H[4:0]A8H[7:0] and XSCC[12:0]ADH[4:0]ACH[7:0]) are defined independently, but must be set in a 2 : 1 relation in the actual data path implementation. The phase offsets XPHY[7:0]AAH[7:0] and XPHC[7:0]AEH[7:0] can be used to shift the sample phases slightly. XPHY[7:0] and XPHC[7:0] covers the phase offset range 7.999T to 1⁄32T. The phase offsets should also be programmed in a 2 : 1 ratio. The underlying phase controlling DTO has a 13-bit resolution. The line buffer can also be used for mirroring, i.e. for flipping the image left to right, for the vanity picture in video phone application (bit YMIR[B4H[4]]). In mirror mode only one active prescaled line can be held in the FIFO at a time. According to the equations Npix_in 1 XSCY[12:0] = 1024 × -------------------- × ----------------------- and XPSC Npix_out The line buffer can be utilized as excessive pipeline buffer for discontinuous and variable rate transfer conditions at expansion port or image port. XSCY[12:0] XSCC[12:0] = ------------------------------- the VPD covers the scale 2 range from 0.125 to zoom 3.5. VPD acts equivalent to a polyphase filter with 64 possible phases. In combination with the prescaler, it is possible to get very accurate samples from a highly anti-aliased integer down-scaled input picture. VERTICAL SCALING The vertical scaler of the SAA7114H consists of a line FIFO buffer for line repetition and the vertical scaler block, which implements the vertical scaling on the input data stream in 2 different operational modes from theoretical zoom by 64 down to icon size 1⁄64. The vertical scaler is located between the BCS and horizontal fine scaler, so that the BCS can be used to compensate the DC gain amplification of the ACM mode (see Section 8.3.3.2) as the internal RAMs are only 8-bit wide. 2000 Mar 15 Line FIFO buffer (subaddresses 91H, B4H and C1H, E4H) The line FIFO buffer is a dual ported RAM structure for 768 pixels, with asynchronous write and read access. The line buffer can be used for various functions, but not all functions may be available simultaneously. The horizontal fine scaling (VPD) should operate at scaling ratios between 1⁄2 and 2 (0.8 and 1.6), but can also be used for direct scale in the range from 1⁄7.999 to (theoretical) zoom 3.5 (restriction due to the internal data path architecture), without prescaler. 8.3.3 SAA7114H 47 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler 8.3.3.2 Vertical scaler (subaddresses B0H to BFH and E0H to EFH) SAA7114H and field rate conversion are supported (i.e. de-interlacing, re-interlacing). Vertical scaling of any ratio from 64 (theoretical zoom) to 1⁄ (icon) can be applied. 63 Figs 28 and 29 and Tables 12 and 13 are describing the use of the offsets. The vertical scaling block consists of another line delay, and the vertical filter structure, that can operate in two different modes. Called linear interpolation (LPI) and accumulation (ACM) mode, controlled by YMODE[B4H[0]]. Remark: The vertical start phase, as well as scaling ratio are defined independently for luminance and chrominance channel, but must be set to the same values in the actual implementation for accurate 4 : 2 : 2 output processing. • LPI mode: In Linear Phase Interpolation (LPI) mode (YMODE = 0) two neighbouring lines of the source video stream are added together, but weighted by factors corresponding to the vertical position (phase) of the target output line relative to the source lines. This linear interpolation has a 6-bit phase resolution, which equals 64 intra line phases. It interpolates between two consecutive input lines only. LPI mode should be applied for scaling ratios around 1 (down to 1⁄2), it must be applied for vertical zooming. The vertical processing communicates on it’s input side with the line FIFO buffer. The scale related equations are: • Scaling increment calculation for ACM and LPI mode, down-scale and zoom: Nline_in YSCY(C)[15:0] = lower integer of 1024 × ------------------------- Nline_out • BCS value to compensate DC gain in ACM mode (contrast and saturation have to be set): CONT[7:0]A5H[7:0] respectively SATN[7:0]A6H[7:0] • ACM mode: The vertical Accumulation (ACM) mode (YMODE = 1) represents a vertical averaging window over multiple lines, sliding over the field. This mode also generates phase correct output lines. The averaging window length corresponds to the scaling ration, resulting in an adaptive vertical low-pass effect, to greatly reduce aliasing artefacts. ACM can be applied for down-scales only from ratio 1 down to 1⁄64. ACM results in a scale dependent DC gain amplification, which has to be precorrected by the BCS control of the scaler part. Nline_out = lower integer of ------------------------- × 64 , or Nline_in 1024 = lower integer of ------------------------------- × 64 YSCY[15:0] 8.3.3.3 As shown in Section 8.3.1.3, the scaler processing may run randomly over the interlaced input sequence. Additionally the interpretation and timing between ITU 656 field ID and real-time detection by means of the state of H-sync at falling edge of V-sync may result in different field ID interpretation. The phase and scale controlling DTO calculates in 16-bit resolution, controlled by parameters YSCY[15:0]B1H[7:0]B0H[7:0] and YSCC[15:0]B3H[7:0]B2H[7:0], continuously over the entire filed. A start offset can be applied to the phase processing by means of the parameters YPY3[7:0] to YPY0[7:0] in BFH[7:0] to BCH[7:0] and YPC3[7:0] to YPC0[7:0] in BBH[7:0] to B8H[7:0]. The start phase covers the range of 255⁄32 to 1⁄32 lines offset. Also a vertically scaled interlaced output gets a larger vertical sampling phase error, if the interlaced input fields are processed, without regarding the actual scale at the starting point of operation (see Fig.28). Four events are to be considered, they are illustrated in Fig.29.

SAA7114H The registers are assigned to the following events; e.g. subaddresses B8H to BBH: • B8H: 00 = input field ID 0, task status bit 0 (toggle status, see Section 8.3.1.3) Please notice that the equations of Fig.29 are producing an interpolated output also for the unscaled case, as the geometrical reference position for all conversions is the position of the first line of the lower field (see Table 12). • B9H: 01 = input field ID 0, task status bit 1 • BAH: 10 = input field ID 1, task status bit 0 • BBH: 11 = input field ID 1, task status bit 1. If there is no need for UP-LO and LO-UP conversion and the input field ID is the reference for the back-end operation, then it is UP-LO = UP-UP and LO-UP = LO-LO and the 1⁄2 line phase shift (PHO + 16) can be skipped. This case is listed in Table 13. Dependent on the input signal (interlaced or non-interlaced) and the task processing (50 Hz or field reduced processing with one or two tasks, see examples in Section 8.3.1.3), also other combinations may be possible, but the basic equations are the same. The SAA7114H supports 4 phase offset registers per task and component (luminance and chrominance). The value of 20H represents a phase shift of one line.

The SAA7114H contains a versatile VBI-data decoder. The implementation and programming model accords to the VBI-data slicer built in the multimedia video data acquisition circuit SAA5284. To adjust the slicers processing to the input signal source, there are offsets in horizontal and vertical direction available: parameters HOFF[10:0]5BH[2:0]59H[7:0], VOFF[8:0]5BH[4]5AH[7:0] and FOFF[5BH[7]]). The circuitry recovers the actual clock phase during the clock run-in period, slices the data bits with the selected data rate, and groups them to bytes. The result is buffered into a dedicated VBI-data FIFO with a capacity of 2 × 56 bytes (2 × 14 Dwords). The clock frequency, signals source, field frequency, accepted error count must be defined in subaddress 40H. Contrary to the scalers counting, the slicers offsets are defining the position of the H and V trigger events related to the processed video field. The trigger events are the falling edge of HREF and the falling edge of V123 from the decoder processing part. The relation of these programming values to the input signal and the recommended values can be seen in Tables 4 to 7. The supported VBI-data standards are shown in Table 14. For lines 2 to 24 of a field, per VBI line, 1 of 16 standards can be selected (LCR24_[7:0] to LCR2_[7:0] in 57H[7:0] to 41H[7:0]: 23 × 2 × 4 bit programming bits).

Image port output formatter (subaddresses 84H to 87H) As further operation the serialization of the internal 32-bit Dwords to 8-bit or optional 16-bit output, as well as the insertion of the extended ITU 656 codes (SAV/EAV for video data, ANC or SAV/EAV codes for sliced text data) are done here. The output interface consists of a FIFO for video and for sliced text data, an arbitration circuit, which controls the mixed transfer of video and sliced text data over the I-port and a decoding and multiplexing unit, which generates the 8 or 16-bit wide output data stream and the accompanied reference and supporting information. For handshake with the VGA controller, or other memory or bus interface circuitry, programmable FIFO flags are provided (see Section 8.5.2). The clock for the output interface can be derived from an internal clock, decoder, expansion port, or an externally provided clock which is appropriate for e.g. VGA and frame buffer. The clock can be up to 33 MHz. The scaler provides the following video related timing reference events (signals), which are available on pins as defined by subaddresses 84H and 85H: 8.5.1 SCALER OUTPUT FORMATTER (SUBADDRESSES 93H AND C3H) The output formatter organizes the packing into the output FIFO. The following formats are available: YUV 4 : 2 : 2, YUV 4 : 1 : 1, YUV 4 : 2 : 0, YUV 4 : 1 : 0, Y only (e.g. for raw samples). The formatting is controlled by FSI[2:0]93H[2:0], FOI[1:0]93H[4:3] and FYSK[93H[5]]. • Output field ID • Start and end of vertical active video range, • Start and end of active video line • Data qualifier or gated clock The data formats are defined on Dwords, or multiples, and are similar to the video formats as recommended for PCI multimedia applications (compare SAA7146A), but planar formats are not supported. • Actually activated programming page (if CONLH is used) • Threshold controlled FIFO filling flags (empty, full, filled) FSI[2:0] defines the horizontal packing of the data, FOI[1:0] defines, how many Y only lines are expected, before a Y/C line will be formatted. If FYSK is set to logic 0 preceding Y only lines will be skipped, and output will always start with a Y/C line. • Sliced data marker. The disconnected data stream at the scaler output is accompanied by a data valid flag (or data qualifier), or is transported via a gated clock. Clock cycles with invalid data on the I-port data bus (including the HPD pins in 16-bit output mode) are marked with code 00H. Additionally the output formatter limits the amplitude range of the video data (controlled by ILLV[85H[5]]); see Table 17. The output interface also arbitrates the transfer between scaled video data and sliced text data over the I-port output.

The decoded VBI-data is lead by the ITU ancillary data header (DID[5:0]5DH[5:0] at value <3EH) or by SAV/EAV codes selectable by DID[5:0] at value 3EH or 3FH. IGP0 or IGP1 is set, if the first byte of the ANC header is valid on the I-port bus. It is reset, if an SAV occurs. So it may frame multiple lines of text data output, in case video processing starts with a distance of several video lines to the region of text data. Valid sliced data from the text FIFO are available on the I-port as long as the IGP0 or IGP1 flag is set and the data qualifier is active on pin IDQ. The image port, and the video FIFO, can operate with the video source clock (synchronous mode) or with externally provided clock (asynchronous, and burst mode), as appropriate for the VGA controller or attached frame buffer. The video FIFO provides 4 internal flags, reporting to which extent the FIFO is actually filled. These are: • The FIFO Almost Empty (FAE) flag • The FIFO Combined Flag (FCF) or FIFO filled, which is set at almost full level and reset, with hysteresis, only after the level crosses below the almost empty mark The decoded VBI-data are presented in two different data formats, controlled by bit RECODE. • RECODE = 1: values 00H and FFH will be recoded to even parity values 03H and FCH • The FIFO Almost Full (FAF) flag • The FIFO Overflow (FOVL) flag. • RECODE = 0: values 00H and FFH may occur in the data stream as detected. The trigger levels for FAE and FAF are programmable by FFL[1:0]86H[3:2] (16, 24, 28, full) and FEL[1:0]86H[1:0] (16, 8, 4, empty). 8.5.4 The state of this flag can be seen on the pins IGP0 or IGP1. The pin mapping is defined by subaddresses 84H and 85H (see Section 9.5). VIDEO AND TEXT ARBITRATION (SUBADDRESS 86H) Sliced text data and scaled video data are transferred over the same bus, the I-port. The mixed transfer is controlled by an arbitration circuitry. If the video data are transferred without any interrupt and the video FIFO does not need to buffer any output pixel, the text data are inserted after an end of a scaled video line, normally during the blanking interval of the video. TEXT FIFO In the text FIFO the data of the terminal VBI-data slicer are collected before the transmission over the I-port is requested (normally before the video window starts). It is partitioned into two FIFO sections. A complete line is filled into the FIFO, before a data transfer is requested. So normally, one line text data is ready for transfer, while the next text line is collected. So sliced text data are delivered as a block of qualified data, without any qualification gaps in the byte stream of the I-port. 2000 Mar 15 UPPER RANGE The decoded VBI-data is collected in the dedicated VBI-data FIFO. After capture of a line is completed, the FIFO can be streamed through the image port, preceded by a header, telling line number and standard. The video FIFO at the scaler output contains 32 Dwords. That corresponds to 64 pixels in 16-bit YUV 4 : 2 : 2 format. But as the entire scaler can act as pipeline buffer, the actually available buffer capacity for the image port is much higher, and can exceed beyond a video line. 8.5.3 LOWER RANGE 54 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler 8.5.5 DATA STREAM CODING AND REFERENCE SIGNAL 84H, 85H AND 93H) SAA7114H If ITU 656 like codes are not wanted, these codes can be suppressed in the output stream. GENERATION (SUBADDRESSES As H and V reference signals are logic 1, active gate signals are generated, which are framing the transfer of the valid output data. Alternative to the gates, H and V trigger pulses are generated on the rising edges of the gates. As further option, it is possible to provide the scaler with a gating external signal on pin ITRDY. So it is possible to hold the data output for a certain time and to get valid output data in bursts of a guaranteed length. The sketched reference signals and events can be mapped to the I-port output pins IDQ, IGPH, IGPV, IGP0 and IGP1. For flexible use the polarities of all the outputs can be modified. The default polarity for the qualifier and reference signals is logic 1 (= active). Due to the dynamic FIFO behaviour of the complete scaler path, the output signal timing has no fixed timing relation to the real-time input video stream. So fixed propagation delays, in therms of clock cycles, related to the analog input can not be defined. Table 18 shows the relevant and supported SAV and EAV coding. The data stream is accompanied by a data qualifier. Additionally invalid data cycles are marked with code 00H.

An audio sample clock, that is locked to the field frequency, makes sure that there is always the same predefined number of audio samples associated with a field, or a set of fields. That ensures synchronous playback of audio and video after digital recording (e.g. capture to hard disk), MPEG or other compression, or non-linear editing. 8.6.1 SAA7114H See Table 21 for examples. Remark: For standard applications the synthesized audio clock AMCLK can be used directly as master clock and as input clock for port AMXCLK (short cut) to generate ASCLK and ALRCLK. For high-end applications it is recommended to use an external analog PLL circuit to enhance the performance of the generated audio clock. MASTER AUDIO CLOCK The audio clock is synthesized from the same crystal frequency as the line-locked video clock is generated.

Additionally, there are two differential reference inputs, which must be connected to ground via a capacitor equivalent to the decoupling capacitors at the 6 inputs.

It is locked to the selected video input, generating baseband video pixels according to “ITU recommendation 601”. In order to support interfacing circuitries, a direct pixel clock LLC2 is also provided. For the generation of the line-locked video (pixel) clock LLC, and of the frame locked audio serial bit clock, a crystal accurate frequency reference is required. An oscillator is built in, for fundamental or third harmonic crystals. The supported crystal frequencies are 32.11 or 24.576 MHz (defined during reset by strapping pin ALRCLK). The pins for line and field timing reference signals are RTCO, RTS1 and RTS0. Various real-time status information can be selected for the RTS pins. The signals are always available (output) and reflect the synchronization operation of the decoder part in the SAA7114H. The function of the RTS1 and RTS0 pins can be defined by bits RTSE1[3:0]12H[7:4] and RTSE0[3:0]12H[3:0]. Alternatively pin XTALI can be driven from an external single ended oscillator. The crystal oscillation can be propagated as clock to other ICs in the system via pin XOUT.

The data transfers through the expansion port represent a single D1 port, with half duplex mode. The SAV and EAV codes may be inserted optionally for data input (controlled by bit XCODE[92H[3]]). The input/output direction is switched for complete fields, only. The expansion port is intended for transporting video streams image data from other digital video circuits like MPEG encoder/decoder and video phone codec, to the image port (I-port). The expansion port consists of two groups of signals/pins: • 8-bit data, I/O, regularly components video YUV 4 : 2 : 2, i.e. CB-Y-CR-Y, byte serial, exceptionally raw video samples (e.g. ADC test). In input mode the data bus can be extended to 16-bit by the pins HPD7 to HPD0. • Clock, synchronization and auxiliary signals, accompanying the data stream, I/O.

For nominal levels see Fig.18. X-PORT CONFIGURED AS OUTPUT If data output is enabled at the expansion port, then the data stream from the decoder is presented. The data format of the 8-bit data bus is dependent on the chosen data type, selectable by the line control registers LCR2 to LCR24; see Table 3. In contrast to the image port, the sliced data format is not available on the expansion port. Instead, raw CVBS samples are always transferred if any sliced data type is selected. The relation of LCR programming to line numbers is described in Section 8.2, see Tables 4 to 7. • Active video (data type 15) contains component YUV 4 : 2 : 2 signal, 720 active pixels per line. The amplitude and offsets are programmable via DBRI7 to DBRI0, DCON7 to DCON0, DSAT7 to DSAT0, OFFU1, OFFU0, OFFV1 and OFFV0. For nominal levels see Fig.17. The data type selections by LCR are overruled by setting OFTS2 (subaddress 13H bit 2) = 1. This setting is mainly intended for device production test. The VPO-bus carries the upper or lower 8 bits of the two ADCs dependent on OFTS[1:0]13H[1:0] settings; see Table 57. The output configuration is done via MODE[3:0]02H[3:0] settings; see Table 39. If a YC mode is selected, the expansion port carries the multiplexed output signals of both ADCs, in CVBS mode the output of only one ADC. No timing reference codes are generated in this mode. • Test line (data type 6) is similar to active video format, with some constraints within the data processing: Remark: The LSBs (bit 0) of the ADCs are also available on pin RTS0. For details see Table 55. – adaptive chrominance comb filter, vertical filter (chrominance comb filter for NTSC standards, PAL phase error correction) within the chrominance processing are disabled The SAV/EAV timing reference codes define start and end of valid data regions. During horizontal blanking period between EAV and SAV the ITU-blanking code sequence ‘- 80 - 10 - 80 - 10 -...’ is transmitted. – adaptive luminance comb filter, peaking and chrominance trap are bypassed within the luminance processing. The position of the F-bit is constant according to ITU 656 (see Tables 29 and 30). Following are some details of data types on the expansion port: The V-bit can be generated in two different ways (see Tables 29 and 30) controlled via OFTS1 and OFTS0, see Table 57. This data type is defined for future enhancements. It could be activated for lines containing standard test signals within the vertical blanking period. Currently the most sources do not contain test lines. For nominal levels see Fig.17. F and V bits change synchronously with the EAV code. • Raw samples (data types 0 to 5 and 7 to 14): UV-samples are similar to data type 6, but CVBS samples are transferred instead of processed luminance samples within the Y time slots.

In this event the code sequence is replaced by the standard ‘- 80 - 10 -’ blanking values. 2. If raw samples or sliced data are selected by the line control registers (LCR2 to LCR24), the Y-samples are replaced by CVBS samples. 2000 Mar 15 63 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler SAA7114H Table 28 SAV/EAV format on expansion port XPD7 to XPD0 BIT 6 (F) BIT 7 1 BIT 5 (V) field bit BIT 4 (H) vertical blanking bit BIT 3 BIT 2 BIT 1 BIT 0 (P3) (P2) (P1) (P0) format 1st field: F = 0 VBI: V = 1 H = 0 in SAV format 2nd field: F = 1 active video: V = 0 H = 1 in EAV format reserved; evaluation not recommended (protection bits according to ITU 656) for vertical timing see Tables 29 and 30 Table 29 525 lines/60 Hz vertical timing V LINE NUMBER F (ITU 656) OFTS[2:0] = 000 (ITU 656) 1 to 3 1 OFTS[2:0] = 001 1 4 to 19 0 1 20 0 0 21 0 0 22 to 261 0 0 262 0 0 263 0 0 264 and 265 0 1 266 to 282 1 1 283 1 0 284 1 0 285 to 524 1 0 525 1 0 according to selected VGATE position type via VSTA and VSTO (subaddresses 15H to 17H); see Tables 59 to 61 Table 30 625 lines/50 Hz vertical timing V LINE NUMBER F (ITU 656) OFTS[2:0] = 000 (ITU 656) 1 to 22 0 1 23 0 0 24 to 309 0 0 310 0 0 311 and 312 0 1 313 to 335 1 1 336 1 0 337 to 622 1 0 623 1 0 624 and 625 1 1 2000 Mar 15 64 OFTS[1:0] = 10 according to selected VGATE position type via VSTA and VSTO (subaddresses 15H to 17H); see Tables 59 to 61 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler 9.4.2 Available formats are: X-PORT CONFIGURED AS INPUT • YUV 4 : 2 : 2, If data input mode is selected at the expansion port, then the scaler can choose it’s input data stream from the on-chip video decoder, or from expansion port (controlled by bit SCSRC[1:0]91H[5:4]). Byte serial YUV 4 : 2 : 2, or subsets for other sampling schemes, or raw samples from an external ADC may be input (see also bits FSC[2:0]91H[2:0]). The input stream must be accompanied by an external clock XCLK, qualifier XDQ and reference signals XRH and XRV. Instead of the reference signal, embedded SAV and EAV codes according to ITU 656 are also accepted. The protection bits are not evaluated. • YUV 4 : 1 : 1, • Raw samples • Decoded VBI-data. For handshake with the receiving VGA controller, or other memory or bus interface circuitry, F, H and V reference signals and programmable FIFO flags are provided. The information will be provided on pins IGP0, IGP1, IGPH and IGPV. The functionality on this pins is controlled via subaddresses 84H and 85H. VBI-data is collected over an entire line in its own FIFO, and transferred as an uninterrupted block of bytes. Decoded VBI-data can be signed by the VBI flag on pin IGP0/1. XRH and XRV carry the horizontal and vertical synchronization signals for the digital video stream through the expansion port. The field ID of the input video stream is carried in the phase (edge) of XRV and state of XRH, or directly as FS (frame sync, odd/even signal) on the XRV pin (controlled by XFDV[92H[7]], XFDH[92H[6]] and XDV1[92H[5]]). As scaled video data and decoded VBI-data may come from different and asynchronous sources, an arbitration scheme is needed. Normally VBI-data slicer has priority. The image port consists of the pins and/or signals, as listed in Table 31. The trigger events on XRH (rising/falling edge) and XRV (rising/falling/both edges) for the scalers acquisition window are defined by XDV[1:0]92H[5:4] and XDH[92H[2]]. Also the signal polarity of the qualifier can be defined (bit XDQ[92H[1]]). Alternatively to a qualifier, the input clock can be applied to a gated clock (means clock gated with a data qualifier, controlled by bit XCKS[92H[0]]). In this event, all input data will be qualified. 9.5 SAA7114H For pin constrained applications, or interfaces, the relevant timing and data reference signals can also get encoded into the data stream. Therefore the corresponding pins do not need to get connected. The minimum image port configuration requires 9 pins only, i.e. 8 pins for data including codes, and 1 pin for clock or gated clock. The inserted codes are defined in close relation to the ITU/CCIR-656 (D1) recommendation, where possible. Image port (I-port) The image port transfers data from the scaler as well as from the VBI-data slicer, if so selected (maximum 33 MHz). The reference clock is available at the ICLK pin, as output, or as input (maximum 33 MHz). As output, ICLK is derived from the locked decoder or expansion port input clock. The data stream from the scaler output is normally discontinuous. Therefore valid data during a clock cycle is accompanied by a data qualifying (data valid) flag on pin IDQ. For pin constrained applications the IDQ pin can be programmed to function as gated clock output (bit ICKS2[80H[2]]). The following deviations from “ITU 656 recommendation” are implemented at SAA7114H’s image port interface: The data formats at the image port are defined in Dwords of 32 bits (4 bytes), like the related FIFO structures. But the physical data stream at the image port is only 16-bit or 8-bit wide; in 16-bit mode data pins HPD7 to HPD0 are used for chrominance data. The four bytes of the Dwords are serialized in words or bytes. • Data stream may be interleaved with not-valid data codes, 00H, but SAV and EAV 4-byte codes are not interleaved with not-valid data codes 2000 Mar 15 • SAV and EAV codes are only present in those lines, where data is to be transferred, i.e. active video lines, or VBI-raw samples, no codes for empty lines • There may be more or less than 720 pixels between SAV and EAV • Data content and number of clock cycles during horizontal and vertical blanking is undefined, and may be not constant • There may be an irregular pattern of not-valid data, or IDQ, and as a result, ‘CB - Y - CR - Y -’ is not in a fixed phase to a regular clock divider 65 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler • VBI-raw sample streams are enveloped with SAV and EAV, like normal video SAA7114H There are no empty cycles in the ancillary code and its data field. The data codes 00H and FFH are suppressed (changed to 01H or FEH respectively) in active video stream, as well as in VBI-raw sample stream (VBI pass-through). Optionally the number range can be limited further. • Decoded VBI-data is transported as Ancillary (ANC) data, two modes: – direct decoded VBI-data bytes (8-bit) are directly placed in the ANC data field, 00H and FFH codes may appear in data block (violation to CCIR-656) – recoded VBI-data bytes (8-bit) directly placed in ANC data field, 00H and FFH codes will be recoded to even parity codes 03H and FCH to suppress invalid CCIR-656 codes.

Functional priority has the I-port. If I8_16[93H[6]] is set to logic 1 the output drivers of the H-port are enabled dependent on the I-port enable control. For I8_16 = 0, the HPD output is disabled.

IGPH and IGPV are sketched as logic 1 active gate signals. If reference pulses are programmed, these pulses are generated on the rising edge of the logic 1 active gates.

But different to this: • It is not necessary to mark invalid cycles with a 00H code • No constraints on the input qualifier (can be a random pattern) • XCLK may be a gated clock (XCLK AND external XDQ).

Details about the JTAG BST-TEST can be found in the specification “IEEE Std. 1149.1”. A file containing the detailed Boundary Scan Description Language (BSDL) description of the SAA7114H is available on request. The SAA7114H has built in logic and 5 dedicated pins to support boundary scan testing which allows board testing without special hardware (nails). The SAA7114H follows the “IEEE Std. 1149.1 - Standard Test Access Port and Boundary-Scan Architecture” set by the Joint Test Action Group (JTAG) chaired by Philips. The 5 special pins are Test Mode Select (TMS), Test Clock (TCK), Test Reset (TRST), Test Data Input (TDI) and Test Data Output (TDO). Table 33 BST instructions supported by the SAA7114H INSTRUCTION 10.1 DESCRIPTION BYPASS This mandatory instruction provides a minimum length serial path (1 bit) between TDI and TDO when no test operation of the component is required. EXTEST This mandatory instruction allows testing of off-chip circuitry and board level interconnections. SAMPLE This mandatory instruction can be used to take a sample of the inputs during normal operation of the component. It can also be used to preload data values into the latched outputs of the boundary scan register. CLAMP This optional instruction is useful for testing when not all ICs have BST. This instruction addresses the bypass register while the boundary scan register is in external test mode. IDCODE This optional instruction will provide information on the components manufacturer, part number and version number. INTEST This optional instruction allows testing of the internal logic (no customer support available). USER1 This private instruction allows testing by the manufacturer (no customer support available). Initialization of boundary scan circuit When the IDCODE instruction is loaded into the BST instruction register, the identification register will be connected between TDI and TDO of the IC. The identification register will load a component specific code during the CAPTURE_DATA_REGISTER state of the TAP controller and this code can subsequently be shifted out. At board level this code can be used to verify component manufacturer, type and version number. The device identification register contains 32 bits, numbered 31 to 0, where bit 31 is the most significant bit (nearest to TDI) and bit 0 is the least significant bit (nearest to TDO); see Fig.38. The TAP (Test Access Port) controller of an IC should be in the reset state (TEST_LOGIC_RESET) when the IC is in functional mode. This reset state also forces the instruction register into a functional instruction such as IDCODE or BYPASS. To solve the power-up reset, the standard specifies that the TAP controller will be forced asynchronously to the TEST_LOGIC_RESET state by setting the TRST pin LOW. 10.2 Device identification codes A device identification register is specified in “IEEE Std. 1149.1b-1994”. It is a 32-bit register which contains fields for the specification of the IC manufacturer, the IC part number and the IC version number. Its biggest advantage is the possibility to check for the correct ICs mounted after production and determination of the version number of ICs during field service. 2000 Mar 15 71 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler MSB handbook, full pagewidth 31 TDI SAA7114H LSB 28 27 12 11 1 nnnn 0111000100010100 00000010101 4-bit version code 16-bit part number 11-bit manufacturer identification 0 TDO 1 MHB557 Fig.38 32 bits of identification code. 11 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134); all ground pins connected together and all supply pins connected together.

To activate the VBI-data slicer, VITX[1:0]86H[7:6] has to be set to ‘11’. Dependent on the VBI-data slicer settings, the sliced VBI-data are inserted after end of scaled video lines, if the regions of VBI-data slicer and scaler overlaps. To compensate the running-in of the vertical scaler, the vertical input window lengths are extended by 2 to 290 lines, respectively 242 lines for XS, but the scaler increment calculations are done with 288, respectively 240 lines. 16.4.3 16.4.1 SAA7114H TRIGGER CONDITION For trigger condition STRC[1:0]90H[1:0] not equal ‘00’. If the value of (YO + YS) is greater equal 262 (NTSC), respectively 312 (PAL) the output field rate is reduced to 30 Hz, respectively 25 Hz. Horizontal and vertical offsets (XO and YO) have to be used to adjust the displayed video in the display window. As this adjustment is application dependent, the listed values are only dummy values. 16.4.2 MAXIMUM ZOOM FACTOR The maximum zoom factor is dependent on the back-end data rate and therefore back-end clock and data format dependent (8 or 16-bit output). The maximum horizontal zoom is limited to about 3.5, due to internal data path restrictions.

A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. 18.2 Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 °C. The top-surface temperature of the packages should preferable be kept below 230 °C. 18.3 Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. – smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. • For packages with leads on four sides, the footprint must be placed at a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 °C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 18.4 Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: • Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. 2000 Mar 15 SAA7114H 135 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler 18.5 SAA7114H Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE REFLOW(1) WAVE BGA, SQFP not suitable HLQFP, HSQFP, HSOP, SMS not PLCC(3), SO, SOJ suitable LQFP, QFP, TQFP SSOP, TSSOP, VSO suitable suitable(2) suitable suitable not recommended(3)(4) suitable not recommended(5) suitable Notes 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”. 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 2000 Mar 15 136 Philips Semiconductors Preliminary specification PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler SAA7114H 19 DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
