Texas Instruments TVP7002PZPR

Overview

TVP7002PZPR from Texas Instruments is a triple-channel 10-bit 165-MSPS video and graphics digitizer with integrated horizontal PLL, supporting RGB/YCbCr 4:4:4 and 4:2:2 output modes, 6-dB to –6-dB programmable analog gain, and embedded sync extraction - used in LCD/DLP/PDP TV front-end digitization and UXGA PC graphics capture.

For engineers reviewing the TVP7002PZPR datasheet, TVP7002PZPR pinout, TVP7002PZPR application, or TVP7002PZPR equivalent, key selection considerations include pixel clock generation range (12–165 MHz), independent per-channel clamp/gain/offset control, 100-pin TQFP PowerPAD thermal performance, and I²C register readback capability for real-time configuration validation.

Technical Context

The TVP7002PZPR integrates three independent analog channels, each with clamping (sync-tip or back-porch), 4-bit coarse analog gain (±6 dB), 6-bit coarse offset (±31 counts), and a 10-bit ADC operating up to 165 MSPS. All channels share a single horizontal PLL generating the sampling clock from HSYNC or SOG inputs.

Its timing processor supports programmable phase alignment (32-step, 11.25° resolution), adjustable loop bandwidth for jitter minimization, and dual sync input paths (HSYNC_A/HSYNC_B, VSYNC_A/VSYNC_B) with internal sync slicer for composite sync-on-green extraction - enabling robust handling of interlaced (480i/1080i) and progressive (720p/1080p/UXGA) formats.

FAQ

What video standards does the TVP7002PZPR support?

The TVP7002PZPR supports SDTV (480i/576i), EDTV (480p/576p), HDTV (720p/1080i/1080p), and PC graphics up to UXGA (1600×1200@60 Hz). It handles both YPbPr component and RGB inputs with embedded sync extraction, and its horizontal PLL generates pixel clocks from 12 MHz to 165 MHz to match these standards. The TVP7002PZPR also supports SCART-RGB 576i via configurable clamp settings.

How does the horizontal PLL in the TVP7002PZPR reduce jitter?

The TVP7002PZPR's horizontal PLL reduces jitter through adjustable loop bandwidth (via charge pump current and VCO range registers), external RC filter components (FILT1/FILT2), and subpixel phase alignment (32-step, 11.25° resolution). Measured clock jitter is 500 ps RMS, enabling clean sampling of high-frequency video signals. The COAST pin maintains stable VCO frequency during vertical blanking intervals where HSYNC is absent - preventing phase discontinuities that cause visible artifacts in TVP7002PZPR output.

Can the TVP7002PZPR operate with only one active video channel?

Yes, the TVP7002PZPR supports single-channel operation. Unused analog inputs (e.g., RIN_2, BIN_3) must be grounded via 10-nF capacitors, and unused digital outputs (e.g., B[9:0] in 4:4:4 mode) can be left unconnected. Each channel's clamp, gain, and offset are independently programmable via I²C, so only the active channel needs configuration. The TVP7002PZPR's power-down mode (PWDN pin) further reduces total dissipation to 15 mW when idle - ideal for multi-source systems with dynamic channel selection.

What is the purpose of the FILT1 and FILT2 pins on the TVP7002PZPR?

FILT1 and FILT2 are dedicated external connections for the horizontal PLL's loop filter network. FILT1 requires a 0.1-μF capacitor in series with a 1.5-kΩ resistor tied to PLL_F (pin 89); FILT2 connects a 4.7-nF capacitor directly to PLL_F. These components define PLL stability, lock time, and jitter performance. Incorrect values cause excessive jitter (>1 ns) or failure to lock across the 12–165 MHz range. The TVP7002PZPR datasheet specifies exact values - deviations degrade timing accuracy and increase bit error rates in downstream video processing.

Does the TVP7002PZPR support both AC- and DC-coupled analog inputs?

The TVP7002PZPR supports AC-coupled analog inputs only. Its internal clamping circuit requires an AC-coupled signal to restore DC level; DC-coupled inputs will saturate the clamp and cause incorrect black-level tracking. The recommended coupling capacitor is 0.1 μF, and unused inputs must be grounded via 10-nF capacitors. The TVP7002PZPR's analog input voltage range is specified as 0.5–2.0 V_P-P, and exceeding this risks clipping or nonlinearity - confirmed in Electrical Characteristics tables for both 110 MSPS and 162 MSPS operation.
