STMicroelectronics STEVAL-CCH002V2

Overview

STEVAL-CCH002V2 from STMicroelectronics is a demonstration board designed to evaluate ST's video switching and signal conditioning ICs-including STHDMI002A (HDMI/DVI TMDS equalizer), STDVE103A/STDVE001A (video decoders), STMAV335/STMAV340 (analog video switches), and associated protection devices. It supports VGA, Y Pb Pr, CVBS, S-video, DVI-I analog, and HDMI/DVI-I digital formats with jumper-selectable routing and real-time status display via a 16×2 backlit LCD.

For engineers reviewing the STEVAL-CCH002V2 datasheet, STEVAL-CCH002V2 pinout, STEVAL-CCH002V2 application, or STEVAL-CCH002V2 equivalent, this board serves as a validated reference for multi-format video signal routing, TMDS equalization, analog/digital switch interoperability, and I/O line protection implementation in broadcast, AV equipment, and multimedia interface designs.

Technical Context

The board integrates discrete video switching ICs operating across distinct signal domains: STHDMI002A handles high-speed TMDS differential signals up to 2.25 Gbps with adaptive equalization; STDVE103A and STDVE001A provide SD/HD analog video decoding with composite/S-video/component inputs; STMAV335 and STMAV340 deliver low-ON-resistance analog video switching (≤5 Ω) for RGB and Y Pb Pr paths. All I/O lines include ESD protection diodes rated to ±15 kV HBM.

Jumper-based configuration enables hardware-selectable signal paths without firmware intervention-supporting simultaneous evaluation of analog routing (VGA/CVBS/S-video/Y Pb Pr), digital routing (HDMI/DVI), and hybrid DVI-I mode. The onboard preprogrammed microcontroller monitors jumper states and drives the LCD to reflect active input/output selections and control signal levels in real time.

FAQ

Does STEVAL-CCH002V2 support HDMI 2.0 or higher?

No. The board implements STHDMI002A, which is specified for HDMI 1.3 and DVI 1.0 compliance with maximum TMDS rate of 2.25 Gbps. It does not support HDMI 2.0's 6 Gbps or higher data rates, nor features like HDR metadata transport or dynamic refresh rate switching.

Can the LCD display be reprogrammed or replaced?

No. The microcontroller is preprogrammed and not field-upgradable; its firmware exclusively reads jumper positions and I/O control signals to drive the fixed-function 16×2 LCD. The display module uses a standard HD44780-compatible interface but lacks user-accessible programming headers or debug interfaces.

Are schematics and layout files provided with the board?

Yes. The official ST document Doc ID 17472 Rev 1 includes six full schematic pages covering all sections: video switching matrices, power distribution, LCD interface, protection networks, and microcontroller logic. PCB layout is not published, but schematic-level design guidance is complete and production-ready.

Is external firmware or PC software required to operate the board?

No. Operation is entirely hardware-driven via jumpers. Signal routing, format selection, and LCD feedback require no host connection, USB interface, or software installation-making it self-contained for bench-level functional verification of ST's video ICs under real signal conditions.
