STEVAL-CCH002V2: HDMI and video switches demonstration board This user manual explains the functions and operation of a demonstration board which supports STHDMI002A, STDVE103A, STDVE001A, STMAV340, and STHDMI002A digital switches/equalizers, and STMAV335 and STMAV340 analog switches, and also different analog buffers and protection devices for analog and digital lines.
The objective of this demonstration board is to display the capabilities of ST’s video switches and buffers and also the appropriate use of signal line protection devices, which have been exhaustively used in this demonstration board at all I/O lines, analog video lines, and high speed transition minimized differential signaling (TMDS) digital signals. The board consists of different input/output connectors and supports various signal formats - VGA (RGB), Y Pb Pr (component video), DVI-I Analog, CVBS (composite video), and S-video in the analog domain and HDMI, DVI-I digital in the digital domain. Demonstration of the various devices is done through appropriate jumper settings on the demonstration board. A 16 character x 2 line backlit alphanumeric LCD, driven by a pre-programmed microcontroller, is also present, which senses the selection lines and displays the active device/signals, switched on, on the LCD.
