The STEVAL-CCH002V2 demonstrates the 
functions and performance of STMicroelectronics’ 
STHDMI002A, STDVE103A, STDVE001A, 
STMAV340, and STHDMI002A digital 
switches/equalizers, and STMAV335 and 
STMAV340 analog switches.

The purpose of the board is to demonstrate the 
capabilities of ST's video switches and buffers 
(while providing an example of the appropriate 
use of signal line protection devices in all I/O 
lines) for both standard analog or high-speed 
TMDS (transition minimized differential signaling) 
digital signals.

The board consists of several input/output 
connectors and supports VGA (RGB), Y Pb Pr 
(component video), DVI-I analog, CVBS 
(composite video) and S-video analog formats, as 
well as HDMI and DVI-I digital formats.

Demonstration of the various devices is achieved 
by setting the appropriate jumpers on the 
demonstration board.

Also included is a 2-line backlit LCD with16 
characters-per-line, which displays the selection 
status as well as the control signals sensed by the 
preprogrammed microcontroller.
