Each channel consists of a clamping circuit, programmable gain control, programmable offset control, and an ADC. Analog Input Switch Control TVP7002 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 TVP7002 supports A/D conversion of SDTV (480i, 576i), EDTV (480p, 576p), and HDTV (720p, 1080i, 1080p) YPbPr component video inputs. The TVP7002 also supports A/D conversion and color space conversion of all standard PC graphics formats (RGB) from VGA up to UXGA. The internal sync separator provides support for field rates (VSYNC frequencies) at or above 40 Hz. Separated VSYNC or an external sync separator must be used to support formats having field rates less than 40 Hz. A summary of the analog video standards supported by the TVP7002 module is show in Table 2. Table 2. Analog Video Standards VIDEO FORMAT VIDEO STANDARDS SDTV (YPbPr component) 480i, 576i EDTV (YPbPr component) 480p, 576p HDTV (YPbPr component) 720p50, 720p60, 1080i50, 1080i60, 1080p50, 1080p60 PC graphics (RGB component) VGA to UXGA SCART (RGB component) 576i Analog Input Clamping The TVP7002 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 ADCs, 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 backporch clamp (a.k.a. fine clamp). The sync-tip clamp always clamps the video sync-tip level near the bottom of the ADC 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.

The fine clamps must also 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 3.

Programmable Gain Control The TVP7002 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 VP-P to 2 VP-P to a fullscale 10-bit A/D output code range. The minimum gain corresponds to a code 0h (2-VP-P full-scale input, –6-dB gain) while the maximum gain corresponds to code Fh (0.5-VP-P 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 TVP7002 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. 12 Submit Documentation Feedback Copyright © 2007–2013, Texas Instruments Incorporated Product Folder Links: TVP7002 TVP7002 www.ti.com SLES206C – MAY 2007 – REVISED APRIL 2013 Automatic Level Control (ALC) The ALC circuit maintains the level of the signal to be set at a value that is programmed at the fine offset I2C register. 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 165 MSPS. All A/D channels receive an identical clock from the on-chip phase-locked loop (PLL) at a frequency between 12 MHz and 165 MHz. All ADC reference voltages are generated internally. Also the external sampling clock 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.

Horizontal PLL Block Diagram The COAST signal is used to allow the 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. 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 165 MHz. The 3-bit loop filter current control register is to control the charge pump current that drives the lowpass loop filter. The applicable current values are listed in the Table 4.

The frequency ranges for the VCO are shown in Table 4. 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.

Multiplexed CbCr data is output on BOUT [9:0] in the 20-bit 4:2:2 output format. 4:4:4 to 4:2:2 conversion is implemented after RGB-to-YCbCr color space conversion. Sync Processing Horizontal Sync Selection The TVP7002 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. Submit Documentation Feedback Copyright © 2007–2013, Texas Instruments Incorporated Product Folder Links: TVP7002 15 TVP7002 SLES206C – MAY 2007 – REVISED APRIL 2013 www.ti.com Sync Slicer TVP7002 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 TVP7002 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 1080p is provided. The internal sync separator provides support for formats having field rates (VSYNC frequencies) at or above 40 Hz. An external sync separator or separated VSYNC must be used for field rates less than 40 Hz. Sync Activity Detection The TVP7002 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 TVP7002 should be configured as an HSYNC input. If AHSO and AVSO are set for automatic selection in I2C Reg 0Eh, the TVP7002 will automatically use the HSYNC and VSYNC inputs, provided signals are present at both inputs. 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 TVP7002 should be used as a digital CSYNC input. If AHSO and AVSO are set for automatic selection, VSYNC will be 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. 16 Submit Documentation Feedback Copyright © 2007–2013, Texas Instruments Incorporated Product Folder Links: TVP7002 TVP7002 www.ti.com SLES206C – MAY 2007 – REVISED APRIL 2013 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 TVP7002 will automatically select the SOG input as the sync source. Table 5. Sync Activity Detection VSYNC INPUT ACTIVITY DETECT HSYNC INPUT ACTIVITY DETECT PC GRAPHICS INPUT TYPE 1 1 5 wire (default) 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). Automatic HSYNC polarity detection is recommended (Reg 0Eh HSPO=0) for all sync types. 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 will provide adequate delay in most applications.

These codes contain the V and F bits that also define vertical timing. Table 7 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 7.

The AVID start location is determined from the HSYNC interval, horizontal back porch interval (Hbp) and a digital process delay factor (PDELAY) required for compensation of internal TVP7002 delays. An additional four bytes must be added to the active pixel interval between AVID start and AVID stop to accommodate embedded sync insertion. AVID Start Pixel = PDELAY + HSYNC + Hbp AVID Stop Pixel = AVID Start Pixel + Active Pixels + 4 NOTE Some AVID Stop Pixel calculations will exceed the HPLL-Feedback Register setting, or total pixels per line. When this occurs, subtract total pixels per line from AVID Stop Pixel. NOTE PDELAY is typically 27 pixels but may vary slightly depending on other TVP7002 settings such as the Sync-on-Green Threshold setting (I2C register 10h) and the SOG LPF setting (I2C register 1Ah). The line numbers where the embedded V-bit and F-bit occur are controlled by I2C registers 44h to 49h, which define the vertical blanking interval and field start positions.

Power Management The TVP7002 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 TVP7002 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 TVP7002 restores power whenever activity is detected on either the selected HSYNC input or the selected SOG input. The TVP7002 can also be placed in power-down mode via the active-high PWDN input (pin 70). When the PWDN input is driven high, the TVP7002 powers down everything including the I2C interface, and the digital outputs are not placed in a high-impedance mode. The TVP7002 can also be placed in a power-down mode using bit 1 of register 0Fh. Individual blocks of the TVP7002 can be independently powered down using register 2Bh.

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 TVP7002 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 TVP7002 devices tied to the same I2C bus, as it controls the least significant bit of the I2C device address Table 9. 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 TVP7002 can respond to two possible chip addresses. The I2 slave address is continuously interpreted from the logic level present at the I2CA terminal. The I2C slave address must be configured with an external connection to either IOGND (I2C address = B8h) or IOVDD (I2C address= BAh). A 2.2-kΩ pullup or pulldown resistor may be used for this connection. Table 10.

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. I2C SCL and SDA signals must not change state until the TVP7002 reset sequence has been completed. Keeping RESETB low prior to any I2C activity will prevent this.
