STEVAL-CCH002V2
Description
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.
