FUNCTIONAL DESCRIPTION The digital video encoder (EURO-DENC) encodes digital luminance and colour difference signals into analog CVBS and simultaneously S-Video signals. NTSC-M, PAL B/G and SECAM standards and sub-standards are supported. The IC also contains Closed Caption and Extended Data Services Encoding (Line 21), and supports anti-taping signal generation in accordance with Macrovision; it also supports overlay via KEY and three control bits by a 24 × 8 LUT. Both interlaced and non-interlaced operation is possible for all standards. A number of possibilities are provided for setting of different video parameters such as: In addition to RED, GREEN and BLUE converted components, the dematrixed YUV input is available on three separate analog outputs. Black and blanking level control Colour subcarrier frequency The basic encoder function consists of subcarrier generation and colour modulation also insertion of synchronization signals. Luminance and chrominance signals are filtered in accordance with the standard requirements of RS-170-A and “CCIR 624”. Variable burst amplitude etc. During reset (RESET = LOW) and after reset is released, all digital I/O stages are set to input mode. A reset forces the I2C-bus interface to abort any running bus transfer and sets register 3A to 03H, register 61 to 06H and registers 6BH and 6EH to 00H. All other control registers are not influenced by a reset. For ease of analog post filtering the signals are twice oversampled with respect to the pixel clock before digital-to-analog conversion. For total filter transfer characteristics see Figs 3, 4, 5, 6, 7 and 8. The DACs for Y, C and CVBS are realized with full 10-bit resolution, DACs for RGB are with 9-bit resolution. Data manager The MPEG port (MP) accept 8 lines multiplexed Cb-Y-Cr data. Depending on the polarity of pin KEY, the MP input (or MP/DP input) or OVL input are selected to be encoded to CVBS and Y/C signals, and output as RGB. In the data manager, real time arbitration on the data stream to be encoded is performed. The 8-bit multiplexed Cb-Y-Cr formats are “CCIR 656” (D1 format) compatible, but the SAV, EAV etc. codes are not decoded. KEY controls OVL entries of a programmable LUT for encoded signals and for RGB output. The common KEY switching signal can be disabled by software for the signals to be encoded (Y, C and CVBS), such that OVL will appear on RGB outputs, but not on Y, C and CVBS. Alternatively, 8-bits Y on MP port and 8-bit multiplexed Cb, Cr on DP port can be chosen as input. A crystal-stable master clock (LLC) of 27 MHz, which is twice the CCIR line-locked pixel clock of 13.5 MHz, needs to be supplied externally. Optionally, a crystal oscillator input/output pair of pins and an on-chip clock driver is provided. OVL input under control of KEY can be also used to insert decoded teletext information or other on-screen data. Optionally, the OVL colour LUTs located in this block, can be read out in a pre-defined sequence (8 steps per active video line), achieving, for example, a colour bar test pattern generator without need for an external data source. The colour bar function is only under software control. It is also possible to connect a Philips Digital Video Decoder (SAA7111 or SAA7151B) in conjunction with a CREF clock qualifier to EURO-DENC. Via RTCI pin connected to RTCO of a decoder, information concerning actual subcarrier, PAL-ID (see “data sheet SAA7111” ) definite subcarrier phase can be inserted. The EURO-DENC synthesizes all necessary internal signals, colour subcarrier frequency, and synchronization signals, from that clock. The encoder is always timing master for the MPEG port (MP), but it can additionally be configured as slave with respect to the RCV trigger inputs. 1996 Jul 08 8 Philips Semiconductors Preliminary specification Digital Video Encoder (EURO-DENC) SAA7182; SAA7183 Encoder CLOSED CAPTION ENCODER VIDEO PATH Using this circuit, data in accordance with the specification of Closed Caption or Extended Data Service, delivered by the control interface, can be encoded (Line 21). Two dedicated pairs of bytes (two bytes per field), each pair preceded by run-in clocks and framing code, are possible. The encoder generates out of Y, U and V baseband signals luminance and colour subcarrier output signals, suitable for use as CVBS or separate Y and C signals. Luminance is modified in gain and in offset (latter programmable in a certain range to enable different black level set-ups). After having been inserted a fixed synchronization level, in accordance with standard composite synchronization schemes, and blanking level, programmable also in a certain range to allow for manipulations with Macrovision anti-taping, additional insertion of AGC super-white pulses, programmable in height, is supported. The actual line number where data is to be encoded in, can be modified in a certain range. Data clock frequency is in accordance with definition for NTSC-M standard 32 times horizontal line frequency. Data LOW at the output of the DACs corresponds to 0 IRE, data HIGH at the output of the DACs corresponds to approximately 50 IRE. It is also possible to encode Closed Caption Data for 50 Hz field frequencies at 32 times horizontal line frequency. In order to enable easy analog post filtering, luminance is interpolated from 13.5 MHz data rate to 27 MHz data rate, providing luminance in 10-bit resolution. This filter is also used to define smoothed transients for synchronization pulses and blanking period. For transfer characteristic of the luminance interpolation filter see Figs 5 and 6. ANTI-TAPING (SAA7183 ONLY) For more information contact your nearest Philips Semiconductors sales office. Chrominance is modified in gain (programmable separately for U and V), standard dependent burst is inserted, before baseband colour signals are interpolated from 6.75 MHz data rate to 27 MHz data rate. One of the interpolation stages can be bypassed, thus providing a higher colour bandwidth, which can be made use of for Y/C output. For transfer characteristics of the chrominance interpolation filter see Figs 3 and 4. RGB processor This block contains a dematrix in order to produce RED, GREEN and BLUE signals to be fed to a SCART plug. Before Y, Cb, Cr signals are dematrixed, 2 times oversampling for luminance and 4 times oversampling for colour difference signals is performed. For transfer curves of luminance and colour difference components of RGB see Figs 7 and 8. The amplitude of inserted burst is programmable in a certain range, suitable for standard signals and for special effects. Behind the succeeding quadrature modulator, colour in 10-bit resolution is provided on subcarrier. SECAM processor SECAM specific pre-processing is achieved in this block by a pre-emphasis of colour difference signals (for gain and phase see Figs 9 and 10. The numeric ratio between Y and C outputs is in accordance with set standards. A baseband frequency modulator with a reference frequency shifted from 4.286 MHz to DC carries out SECAM modulation in accordance with appropriate standard or optionally wide clipping limits. TELETEXT INSERTION AND ENCODING Pin TTX receives a teletext bitstream sampled at the LLC clock, each teletext bit is carried by four or three LLC samples. After the HF pre-emphasis, also applied on a DC reference carrier (anti-Cloche filter; see Figs 11 and 12), line-by-line sequential carriers with black reference of 4.25 MHz (Db) and 4.40625 MHz (Dr) are generated using specified values for FSC programming bytes. Phase variant interpolation is achieved on this bitstream in the internal teletext encoder, providing sufficient small phase jitter on the output text lines. TTXRQ provides a fully programmable request signal to the teletext source, indicating the insertion period of bitstream at lines selectable independently for both fields. The internal insertion window for text is set to 360 teletext bits including clock run-in bits. For protocol and timing see Fig.17. 1996 Jul 08 Alternating phase reset in accordance with SECAM standard is carried out automatically. During vertical blanking the so-called bottle pulses are not provided. 9 Philips Semiconductors Preliminary specification Digital Video Encoder (EURO-DENC) On the RCV2 port, the IC can provide a horizontal pulse with programmable start and stop phase; this pulse can be inhibited in the vertical blanking period to build up, for example, a composite blanking signal. Output interface/DACs In the output interface encoded both Y and C signals are converted from digital-to-analog in 10-bit resolution. Y and C signals are also combined to a 10-bit CVBS signal. The polarity of both RCV1 and RCV2 is selectable by software control. The CVBS output occurs with the same processing delay as the Y and C outputs. Absolute amplitudes at the input of the DAC for CVBS is reduced by 15⁄16 with respect to Y and C DACs to make maximum use of conversion ranges. Field length is in accordance with 50 Hz or 60 Hz standards, including non-interlaced options; start and end of its active part can be programmed. The active part of a field always starts at the beginning of a line, if the standard blanking option SBLBN is not set. RED, GREEN and BLUE signals are also converted from digital-to-analog, each providing a 9-bit resolution. Outputs of the DACs can be set together in two groups via software control to minimum output voltage for either purpose. I2C-bus interface The I2C-bus interface is a standard slave transceiver, supporting 7-bit slave addresses and 400 kbits/s guaranteed transfer rate. It uses 8-bit subaddressing with an auto-increment function. All registers are write only, except one readable status byte. Synchronization Synchronization of the EURO-DENC is able to operate in two modes; slave mode and master mode. Two I2C-bus slave addresses are selected: In the slave mode, the circuit accepts synchronization pulses at the bidirectional RCV1 port. The timing and trigger behaviour related to RCV1 can be influenced by programming the polarity and on-chip delay of RCV1. Active slope of RCV1 defines the vertical phase and optionally the odd/even and colour frame phase to be initialized, it can be also used to set the horizontal phase. 88H: LOW at pin 4 8CH: HIGH at pin 4. Input levels and formats EURO-DENC expects digital Y, Cb, Cr data with levels (digital codes) in accordance with “CCIR 601”. If the horizontal phase is not be influenced by RCV1, a horizontal pulse needs to be supplied at the RCV2 pin. Timing and trigger behaviour can also be influenced for RCV2. For C and CVBS outputs, deviating amplitudes of the colour difference signals can be compensated by independent gain control setting, while gain for luminance is set to predefined values, distinguishable for 7.5 IRE set-up or without set-up. If there are missing pulses at RCV1 and/or RCV2, the time base of EURO-DENC runs free, thus an arbitrary number of synchronization slopes may miss, but no additional pulses (such with wrong phase) must occur. For RGB outputs fixed amplification in accordance with “CCIR 601” is provided. If the vertical and horizontal phase is derived from RCV1, RCV2 can be used for horizontal or composite blanking input or output. Reference levels are measured with a colour bar, 100% white, 100% amplitude and 100% saturation. In the master mode, the time base of the circuit continuously runs free.

The chip-internal sequencer and variable phase interpolation filter minimizes the phase jitter, and thus generates a bandwidth limited signal, which is digital-to-analog converted for the CVBS and Y outputs. Teletext timing Time tFD is the time needed to interpolate input data TTX and inserting it into the CVBS and Y output signal, such that it appears at tTTX = 10.2 µs after the leading edge of the horizontal synchronization pulse. Time tPD is the pipeline delay time introduced by the source that is gated by TTXRQ in order to deliver TTX data. At the TTX input, bit duration scheme repeats after 37 TTX bits or 144 LLC clocks. The protocol demands that TXX bits 10, 19, 28 and 37 are carried by three LLC samples, all others by four LLC samples. After a cycle of 37 TTX bits, the next bits with three LLC samples are bits 47, 56, 65 and 74; this scheme holds for all succeeding cycles of 37 TTX bits, until 360 TTX bits (including 16 run-in bits) are completed. For every additional line with TTX data, the bit duration scheme starts in the same way. Since the pulse representing the TTXRQ signal is fully programmable in duration and rising/falling edges (TTXHS and TTXHE), it always can be ensured that the TTX data is inserted at the correct position of 10.2 µs after the leading edge of outgoing horizontal synchronization pulse. Time tTTXWin is the internally used insertion window for TTX data; it has a constant length that allows insertion of 360 teletext bits (maximum) at a text data rate of 6.9375 bits/s. The insertion window is not opened if the control bit TTXEN is zero. Using appropriate programming, all suitable lines of the odd field (TTXOVS and TTXOVE) plus all suitable lines of the even field (TTXEVS and TTXEVE) can be used for teletext insertion. TELETEXT PROTOCOL The frequency relationship between TTX bit clock and the system clock LLC for 50 Hz field rate is given by the relationship of line frequency multiples, which means 1728/444. handbook, full pagewidth CVBS/Y tTTX textbit #: 1 tTTXWin 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 4 1/LLC 23 24 TTX 4 tPD 3 4 1/LLC 3 4 tFD TTXRQ MGB701 Fig.17 Teletext timing diagram. 1996 Jul 08 33 1996 Jul 08 34 VDDD6 41 VDDD7 49 VDDD8 80 VDDD9 82 100 nF 100 nF 100 nF 100 nF +5 V digital VDDD5 38 100 nF 15 kΩ 15 kΩ 100 nF 100 nF 100 nF VrefH2 VrefH1 VrefL1 74 VrefL2 76 70 VSSD1 to VSSD9 3, 15, 24, 30, 39, 42, 51, 79, 81 SAA7182 SAA7183 72 VSSA VSSA VSSA 100 nF 100 nF 64 60 57 VSSA 67 35 Ω(1) 69 35 Ω(1) 71 35 Ω(1) 73 35 Ω(1) 55 35 Ω(1) 58 35 Ω(1) 61 54 VDDA4 VDDA3 VDDA2 VDDA1 Fig.18 Application environment of the EURO-DENC. 75 100 nF 68 IY/C/CVBS VDDA7 VDDA6 VDDA5 100 nF 53 63 IRGB 100 nF 52 100 nF 45 (1) Typical value.

OUTLINE VERSION REFERENCES IEC JEDEC EIAJ ISSUE DATE 92-11-17 95-03-11 SOT189-2 1996 Jul 08 EUROPEAN PROJECTION 35 Philips Semiconductors Preliminary specification Digital Video Encoder (EURO-DENC) If wave soldering cannot be avoided, the following conditions must be observed: SOLDERING Introduction • A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. • The footprint must be at an angle of 45° to the board direction and must incorporate solder thieves downstream and at the side corners. Even with these conditions, do not consider wave soldering LQFP packages LQFP48 (SOT313-2), LQFP64 (SOT314-2) or LQFP80 (SOT315-1). This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “IC Package Databook” (order code 9398 652 90011). 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. Reflow soldering Reflow soldering techniques are suitable for all LQFP packages. Maximum permissible solder temperature is 260 °C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 °C within 6 seconds. Typical dwell time is 4 seconds at 250 °C. 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. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 °C. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) 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. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 °C. Wave soldering Wave soldering is not recommended for LQFP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices. 1996 Jul 08 SAA7182; SAA7183 36 Philips Semiconductors Preliminary specification Digital Video Encoder (EURO-DENC) SAA7182; SAA7183 DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
