STEVAL-CCH002V2 HDMI and video switches demonstration board Data brief Features 16-character x 2-line alphanumeric backlit LCD VGA input and output connectors S-video input and output connectors Y Pb Pr input and output connector sets CVBS input and output connectors DVI-I input connector Analog and digital switch selection jumper sets Power supply section Reset switch RoHS compliant 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.
