STMicroelectronics STEVAL-CCA005V1

Overview

STEVAL-CCA005V1 from STMicroelectronics is an evaluation board designed specifically for the TSH173 triple video buffer IC, supporting RGB, Y-Pb-Pr, and Y-C-CVBS signal formats with three 6 dB gain channels, integrated 8.2 MHz SD video reconstruction filters, and internal DC level shifters for single-supply operation from 4.5 V to 5.5 V.

For engineers reviewing the STEVAL-CCA005V1 datasheet, STEVAL-CCA005V1 pinout, STEVAL-CCA005V1 application, or STEVAL-CCA005V1 equivalent, this board enables rapid validation of SD video line driving performance, filter response, load drive capability (AC/DC-coupled 150 Ω), harmonic distortion behavior, and DC-level shifting functionality in real-world video interface designs.

Technical Context

The board implements the full signal path of the TSH173: each of its three independent channels includes a unity-gain stable voltage follower with 6 dB fixed gain, a 2nd-order passive RC-LC low-pass filter tuned to 8.2 MHz, and an input-stage DC level shifter to accommodate AC-coupled video sources while operating from a single 5 V supply.

It supports simultaneous evaluation of composite (CVBS), component (Y-Pb-Pr), and RGB video outputs under identical power and layout conditions, with all inputs terminated via 75 Ω and outputs configurable for either AC- or DC-coupled 150 Ω loads - matching broadcast-standard SD video interface requirements.

FAQ

Is STEVAL-CCA005V1 still in active production?

No. STEVAL-CCA005V1 is marked as obsolete per ST's official documentation (Rev 1, May 2008). It remains available through authorized legacy distributors and Aetrix Electronics' extended-life inventory program for design continuity and repair support.

What video standards does this board validate?

This board validates compliance with standard-definition analog video specifications including ITU-R BT.601 (Y-Pb-Pr), SMPTE 259M (SD-SDI baseband timing), and EIA-343A (RGB sync timing), using the TSH173's 8.2 MHz filter cutoff and 6 dB gain to meet SD bandwidth and amplitude requirements.

Can STEVAL-CCA005V1 be used with modern video sources?

Yes - it accepts standard 75 Ω-terminated CVBS, Y-Pb-Pr, or RGB inputs with sync signals, and outputs to professional video monitors or digitizers via BNC or RCA connectors. Its single-supply 5 V operation and DC level shifting allow direct interfacing with legacy and modern SD video gear without external biasing.

Does the board include power supply circuitry?

Yes - it features a dedicated 5 V input header (J1) and on-board filtering capacitors. No onboard voltage regulation is provided; users must supply a clean, low-noise 5 V source capable of ≥500 mA to support all three channels simultaneously under full load.
