The device supports pixel rates up to 90 MHz. Therefore, it can be used for PC graphics digitizing up to WXGA (1440 × 900) resolution at a 60-Hz screen refresh rate, and in video environments for the digitizing of digital TV formats, including HDTV up to 1080i. The TVP70025I is powered from 3.3-V and 1.8-V supply and integrates a triple high-performance analog-to-digital (A/D) converter with clamping functions and variable gain, independently programmable for each channel. The clamp timing window is provided by an external pulse or can be generated internally. The TVP70025I includes analog slicing circuitry on the SOG inputs to support sync-on-luminance or sync-on-green extraction. In addition, TVP70025I can extract discrete HSYNC and VSYNC from composite sync using a sync slicer. The TVP70025I also contains a complete horizontal phase-locked loop (PLL) block to generate a pixel clock from the HSYNC input. Pixel clock output frequencies range from 9 MHz to 90 MHz. All programming of the device is done via an industry-standard I2C interface, which supports both reading and writing of register settings. The TVP70025I is available in a space-saving 100-pin TQFP PowerPAD package.

Each channel consists of a clamping circuit, programmable gain control, programmable offset control, and an A/D converter. Analog Input Switch Control TVP70025I has three analog channels that accept up to ten video inputs. The user can configure the internal analog video switches via the I2C interface. The ten analog video inputs can be used for different input configurations, some of which are: • Up to three SDTV, EDTV, or HDTV component video inputs (limited by number of SOG inputs) • Up to two 5-wire PC graphics inputs (limited by number of HSYNC and VSYNC inputs) The input selection is performed by the input select register at I2C subaddress 19h a 1Ah (see Input Mux Select 1 and Input Mux Select 2). Supported Video Formats The TVP70025I supports A/D conversion of SDTV (480i, 576i), EDTV (480p, 576p), and HDTV (720p, 1080i) YPbPr component video inputs. The TVP70025I also supports A/D conversion and color space conversion of all standard PC graphics formats (RGB) from VGA up to WXGA 60Hz. A summary of the analog video standards supported by the TVP70025I module is shown in the Table below. Analog Video Standards VIDEO FORMAT VIDEO STANDARDS SDTV (YPbPr Component) 480i, 576i EDTV (YPbPr Component) 480p, 576p HDTV (YPbPr Component) 720p, 1080i PC graphics (RGB Component) VGA - XGA 75Hz, WXGA SCART (RGB Component) 576i Analog Input Clamping The TVP70025I provides dc restoration for all analog video inputs including the SOG slicer inputs. The dc restoration circuit (a.k.a. clamp circuit) restores the ac-coupled video signal to a fixed dc level. One dc restoration circuit is implemented prior to each of the three A/D converters, and a fourth one is located prior to the SOG slicer. The dc restoration circuit can be programmed to operate as either a sync-tip clamp (a.k.a. coarse clamp) or a back-porch clamp (a.k.a. fine clamp). The sync-tip clamp always clamps the video sync-tip level near the bottom of the A/D converter range. The back-porch type clamp supports two clamping levels (bottom level and mid level) that are selectable using bits 0, 1, and 2 of register 10h. When using the fine bottom-level clamp, an optional 300-mV common-mode offset may be selected using bit 7 of register 2Ah. In general, the analog video input being used for horizontal synchronization purposes should always use the sync-tip clamp; all other analog video inputs should use the back-porch clamp. The advantage of the back-porch clamp is that it has negligible video droop or tilt across a video line. 12 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): TVP70025I TVP70025I www.ti.com ...................................................................................................................................................................................................... SLES232 – JUNE 2008 The selection between bottom- and mid-level clamping is performed by I2C subaddress 10h (see Section Sync-On-Green Threshold). The fine clamps also must be enabled via I2C register 2Ah for proper operation. The internal clamping time can be adjusted using the I2C clamp start and width registers at subaddress 05h and 06h, respectively (see Clamp Start and Clamp Width). Table 1.

Programmable Gain Control The TVP70025I provides a 4-bit coarse analog gain control (before A/D conversion) and an 8-bit fine digital gain control (after A/D conversion). The coarse analog gain and the fine digital gain are both independently programmable for each ADC channel. Coarse Gain Control The 4-bit coarse analog gain control has a 4:1 linear gain control range defined by the following equation. Coarse Gain = 0.5 + NCG/10, where 0 ≤ NCG ≤ 15 0.5 ≤ Coarse Gain ≤ 2.0 Default: NCG = 7 (Coarse Gain = 1.2) The 4-bit coarse gain control can scale a signal with a voltage-input compliance of 0.5 VPP to 2 VPP to a full-scale 10-bit A/D output code range. The minimum gain corresponds to a code 0h (2-VPP full-scale input, –6-dB gain) while the maximum gain corresponds to code Fh (0.5-VPP full scale, +6-dB gain). The 4-bit coarse gain control is independently controllable for each ADC channel (Red Coarse Gain, Green Coarse Gain, and Blue Coarse Gain). Fine Gain Control The 8-bit fine digital gain control has a 2:1 linear gain control range defined by the following equation. Fine Gain = 1.0 + NFG/256 where 0 ≤ NFG ≤ 255 1.0 ≤ Fine Gain < 2.0 Default: NFG = 0 (Fine Gain = 1.0) The 8-bit fine gain control is independently controllable for each ADC channel (Red Fine Gain, Green Fine Gain, and Blue Fine Gain). For a normal PC graphics input, the fine gain is used mostly. Programmable Offset Control The TVP70025I provides a 6-bit coarse analog offset control (before A/D conversion) and a 10-bit fine digital offset control (after A/D conversion). The coarse analog offset and the fine digital offset are both independently programmable for each ADC channel. Coarse Offset Control A 6-bit code sets the coarse offset (Red Coarse Offset, Green Coarse Offset, Blue Coarse Offset) with individual adjustment per channel. The coarse offset ranges from –32 counts to +31 counts. The coarse offset registers apply before the ADC. Fine Offset Control A 10-bit fine offset registers (Red Fine Offset, Green Fine Offset, Blue Fine Offset) apply after the ADC. The fine offset ranges from –512 counts to +511 counts.

It consists of a pixel averaging filter and feedback loop. This ALC function can be enabled or disabled by the I2C register at subaddress 26h. The ALC circuit needs a timing pulse generated internally but the user should program the position properly. The ALC pulse must be positioned after the clamp pulse. The position of ALC pulse is controlled by ALC placement I2C register at address 31h. This is available only for internal ALC pulse timing. When using an external clamp pulse, the fine clamp and the ALC both start on the leading edge of the external clamp pulse. Therefore, it is recommended to keep the external clamp pulse as long as possible. Analog-to-Digital Converters (ADCs) All ADCs have a resolution of 10 bits and can operate up to 90 MSPS. All A/D channels receive an identical clock from the on-chip phase-locked loop (PLL) at a frequency between 12 MHz and 90 MHz. All ADC reference voltages are generated internally. The external sampling clock also can be used. Horizontal PLL The horizontal PLL generates a high-frequency internal clock used by the ADC sampling and data clocking out to derive the pixel output frequency with programmable phase. The reference signal for this PLL is the horizontal sync signal supplied on the HSYNC input or from extracted horizontal sync of the sync slicer block for embedded sync signals. The horizontal PLL consists of a phase detector, charge pump, loop filter, voltage controlled oscillator (VCO), phase select, feedback divider, and post divider. The horizontal PLL block diagram is shown in Figure 3. PLL Control Register 03h Bit [5:3] COAST HSYNC Phase Detector Charge Pump Loop Filter PLL Control Register 03h Bit [7:6] Phase Select Register 04h Bit [7:3] Post Divider Register 04h Bit [0] VCO Phase Select Post Divider ÷N ADC Sampling CLK N = 1 or 2 Divider External Clock PLL Divide Register 01h and 02h Bit [11:0] Figure 3. Horizontal PLL Block Diagram The COAST signal is used to allow the H-PLL to keep running at the same frequency, in the absence of the incoming HSYNC signal or disordered HSYNC period. This is useful during the vertical sync period, or any other time that the HSYNC is not available. The fine clamp is disabled during the H-PLL coast interval. There are several PLL controls to produce the correct sampling clock. The 12-bit feedback divider register is programmable to select exact multiplication number to generate the pixel clock in the range of 12 MHz to 90 MHz. The 3-bit loop filter current control register is to control the charge pump current that drives the low-pass loop filter. The applicable current values are listed in Table 2. 14 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): TVP70025I TVP70025I www.ti.com ...................................................................................................................................................................................................... SLES232 – JUNE 2008 The purpose of the 2-bit VCO range control is to improve the noise performance of the TVP70025I. The frequency ranges for the VCO are shown in Table 2. The phase of the ADC sample clock generated by the horizontal PLL can be accurately controlled in 32 uniform steps over a single clock period (360/32 = 11.25 degrees phase resolution) using the phase select register located at subaddress 04h. The horizontal PLL characteristics are determined by the loop filter design, the PLL charge pump current, and the VCO range setting. The loop filter design is shown in Figure 4. Supported settings of VCO range and charge pump current for VESA standard display modes are listed in Table 2. 89 PLL_F 4.7 nF 88 1.5 kW 87 0.1 µF FILT2 FILT1 TVP70025I Figure 4.

SLES232 – JUNE 2008 Sync Processing Horizontal Sync Selection The TVP70025I provides two HSYNC inputs and three analog SOG inputs for HDTV and PC graphics inputs. The sync input used by the horizontal PLL is automatically selected based on activity detection. Sync Slicer TVP70025I includes a circuit that compares the input signal on Green channel to a level 150 mV (typical value) above the clamped level (sync tip). The slicing level is programmable by I2C register subaddress at 10h. The digital output of the composite sync slicer is available on the SOGOUT pin. Noise Immunity In general, noise on a slowly varying input signal (i.e., sync falling edge) may cause a voltage comparator to false trigger as the input passes through the linear range of the comparator. To improve the overall performance of the TVP70025I sync slicer in the presence of noise on the SOG input, the voltage comparator includes hysteresis. Maintaining a 50% slice level using the I2C programmable slice level control can further improve the noise immunity of the Sync slicer. The slice level is programmable in 11.2-mV increments over a 350-mV range as follows. slice_level = (350 mV) × (NTH/31) where 0 ≤ NTH ≤ 31, default: 11 0 ≤ slice_level ≤ 350 mV Glitch Immunity During white-to-black transitions, the input video waveform may undershoot below the sync slicer threshold. To help attenuate the amplitude of such glitches, a single-pole low-pass filter with three selectable cutoff frequencies (2.5, 10, and 33 MHz) is provided at the input of the SOG voltage comparator circuit. This filter is bypassed in the default mode. NOTE: Although the low-pass filter may attenuate the amplitude of glitches present on the SOG input, it also makes the sync falling edge less sharp. Sync Separator The sync separator automatically extracts VSYNC and HSYNC from the sliced composite sync input supplied at the SOG input. The G or Y input containing the composite sync must be ac coupled to the SOG input pin using a 1-nF capacitor. Support for PC graphics, SDTV, EDTV, and HDTV up to 1080i is provided. Sync Activity Detection The TVP70025I provides activity detection on the sync inputs (VSYNC, HSYNC) to enable the host processor to determine whether the PC graphics source is configured as a 3-wire, 4-wire, or 5-wire interface as defined here: • 5 wire (G, B, R, HSYNC, VSYNC) • 4 wire (G, B, R, CSYNC) • 3 wire (G, B, R with SOG) If activity is detected on the VSYNC input, the host processor should assume that the PC graphics input is a standard 5-wire interface. In this case, the HSYNC input of the TVP70025I should be configured as an HSYNC input. If AHSO and AVSO are set for automatic selection in I2C Reg 0Eh, the TVP70025I automatically uses the HSYNC and VSYNC inputs, provided signals are present at both inputs. Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): TVP70025I 17 TVP70025I SLES232 – JUNE 2008 ...................................................................................................................................................................................................... www.ti.com If activity is detected on the HSYNC input but not on the VSYNC input, the host processor should assume that the PC graphics input is a standard 4-wire interface. In this case, the HSYNC input of the TVP70025I should be used as a digital CSYNC input. If AHSO and AVSO are set for automatic selection, VSYNC is properly decoded from the CSYNC input, provided no signal is present at the VSYNC input pin. Some test sources output CSYNC on both the HSYNC pin and the VSYNC pin. In this case, the active VSYNC source (AVSS) must be manually set to Sync separated VSYNC in Reg 0Eh. The TVP70025I supports the following two types of CSYNC inputs. CSYNC = VSYNC XOR HSYNC (default) CSYNC = VSYNC OR HSYNC If activity is not detected on either the HSYNC input or the VSYNC input, the host processor should assume that the PC graphics input is a standard 3-wire interface. With AHSO and AVSO set for automatic selection and no signals present at the HSYNC and VSYNC input pins, the TVP70025I automatically selects the SOG input as the sync source. VSYNC INPUT ACTIVITY DETECT HSYNC INPUT ACTIVITY DETECT PC GRAPHICS INPUT TYPE 1 1 5 wire (default) 1 0 Undefined (assume 5 wire) 0 1 4 wire 0 0 3 wire The activity detection status for the VSYNC and HSYNC inputs is written to the I2C status register at subaddress 14h. NOTE: Pin 13 of a standard 15-pin VGA video connector can be either a horizontal sync (HSYNC) or a composite sync (CSYNC). NOTE: For component video inputs, the active HSYNC and VSYNC should always be derived from the selected SOG input. This can most easily be ensured by setting the AHSO, AVSO, AHSS and AVSS bit fields in register 0Eh to logic 1. NOTE: For proper operation when separate HSYNC and VSYNC inputs are used, the leading edge of VSYNC must not be precisely aligned with the leading edge of HSYNC. A simple RC delay circuit provides adequate delay in most applications. 18 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): TVP70025I TVP70025I www.ti.com ......................................................................................................................................................................................................

SLES232 – JUNE 2008 Embedded Syncs Standard embedded syncs insert SAV and EAV codes into the data stream on the rising and falling edges of AVID. These codes contain the V and F bits that also define vertical timing. Table 4 gives the format of the SAV and EAV codes. H = 1 always indicates EAV. H = 0 always indicates SAV. The alignment of V and F to the line and field counter varies depending on the standard. The P bits are protection bits: P3 = V xor H P2 = F xor H P1 = F xor V P0 = F xor V xor H Table 4.

NOTE: When enabled (bit 0 of subaddress 15h), embedded syncs are present in both the Y and C outputs. Output Range Limits The TVP70025I provides selectable output range limits in I2C subaddress 15h: 00 = RGB coding range (Y, Cb, and Cr range from 0 to 1023) (default) 01 = Extended coding range (Y, Cb, and Cr range from 4 to 1019) 10 = ITU-R BT.601 coding range (Y ranges from 64 to 940, Cb and Cr range from 64 to 960) 11 = Reserved NOTE: RGB coding range not allowed with embedded syncs. Power Management The TVP70025I supports both automatic and manual power-down modes. The automatic power-down mode can be selected by setting bit 2 of subaddress 0Fh to logic 0. In the automatic power-down mode, the TVP70025I powers down the ADCs, the ADC reference, and horizontal PLL when activity is not detected on both the selected HSYNC input and the selected SOG input (VSYNC is no longer used). The TVP70025I restores power whenever activity is detected on either the selected HSYNC input or the selected SOG input. The TVP70025I also can be placed in power-down mode via the active-high PWDN input (pin 70). When the PWDN input is driven high, the TVP70025I powers down everything including the I2C interface, and the digital outputs are not placed in a high-impedance mode. The TVP70025I also can be placed in a power-down mode using bit 1 of register 0Fh. Individual blocks of the TVP70025I can be independently powered down using register 2Bh.

SLES232 – JUNE 2008 I2C Host Interface Communication with the TVP70025I device is via an I2C host interface. The I2C standard consists of two signals, serial input/output data (SDA) line and input clock line (SCL), which carry information between the devices connected to the bus. A third signal (I2CA) is used for slave address selection. Although an I2C system can be multi-mastered, the TVP70025I can function as a slave device only. Since SDA and SCL are kept open drain at logic high output level or when the bus is not driven, the user should connect SDA and SCL to a positive supply voltage via a pullup resistor on the board. SDA is implemented bidirectional. The slave addresses select, terminal 73 (I2CA), enables the use of two TVP70025I devices tied to the same I2C bus, as it controls the least significant bit of the I2C device address Table 5. I2C Host Interface Terminal Description SIGNAL TYPE I2CA I Slave address selection DESCRIPTION SCL I Input clock line SDA I/O Input/output data line Reset and I2C Bus Address Selection The TVP70025I can respond to two possible chip addresses. The address selection is made at reset by an externally supplied level on the I2CA pin. The TVP70025I device samples the level of terminal 73 at power up or at the trailing edge of RESETB and configures the I2C bus address bit A0. The I2CA terminal has an internal pulldown resistor to pull the terminal low to set a zero. Table 6.

RESETB may be low during power up, but must remain low for at least 1 µs after the power supplies become stable. Alternatively, reset may be asserted any time with minimum 5-ms delay after power-up and must remain asserted for at least 1 µs. Reset timing is shown in Figure 7.
