STMicroelectronics STEVAL-CCA006V1

Overview

STEVAL-CCA006V1 from STMicroelectronics is an evaluation board designed to validate the TSH173 triple video buffer IC, supporting RGB, Y-Pb-Pr, and Y-C-CVBS signal paths with 6 dB gain per channel, 8.2 MHz reconstruction filters, and DC level shifting for standard-definition video line driving.

For engineers reviewing the STEVAL-CCA006V1 datasheet, STEVAL-CCA006V1 pinout, STEVAL-CCA006V1 application, or STEVAL-CCA006V1 equivalent, this board enables rapid functional validation of single-supply (4.5–5.5 V) SD video buffering, filter response verification, and AC/DC-coupled 150 Ω load drive capability in broadcast, set-top box, and analog video interface designs.

Technical Context

The board implements the TSH173's full signal chain: three independent channels each integrate a 6 dB fixed-gain buffer followed by a 2nd-order low-pass filter with precisely trimmed 8.2 MHz –3 dB cutoff, meeting ITU-R BT.601 SD video bandwidth requirements. Input DC level shifters enable compatibility with both AC-coupled and DC-coupled video sources without external biasing.

All outputs are configured for direct connection to 150 Ω video loads-supporting both AC-coupled (capacitor-input) and DC-coupled (resistor-terminated) termination schemes-and maintain <0.05% THD+N across 0–5 MHz at 1 V_PP, ensuring minimal color fidelity loss in composite and component video paths.

FAQ

Is STEVAL-CCA006V1 still in active production?

No. STEVAL-CCA006V1 is marked Obsolete by STMicroelectronics as of its May 2008 release. It remains available through authorized legacy distributors and Aetrix Electronics' extended-life inventory program for design continuity and repair support in installed SD video systems.

What video signal types can be evaluated using this board?

The board supports RGB (three separate channels), Y-Pb-Pr (component), and Y-C-CVBS (composite + S-video) signal paths. Each channel uses identical TSH173 circuitry, enabling simultaneous evaluation of multiple SD analog video standards on a single PCB layout.

Does the board include input/output connectors compatible with standard test equipment?

Yes. STEVAL-CCA006V1 features BNC connectors for all three video inputs and three corresponding BNC outputs, plus a 2-pin screw terminal for 4.5–5.5 V DC power. This allows direct connection to oscilloscopes, video signal generators, and broadcast monitoring equipment without adapter cables.

Can the TSH173's internal DC level shifter be bypassed for custom biasing?

No. The internal DC level shifter is hardwired and non-configurable on the TSH173. However, the evaluation board provides test points at each channel's input and output nodes, enabling external DC bias injection or measurement before and after the shifter stage for characterization purposes.
