HDMI and video switches using the
STEVAL-CCH002V1 demonstration board
Introduction
This document explains the functioning and operation of the STEVAL-CCH002V1
demonstration board which demonstrates the functionalities of the STMAV335, STMAV340,
STHDMI002A and STDVE003A analog and digital video switches.
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, whether it is standard analog
or high-speed transition minimized differential signaling (TMDS) digital signals.
Demonstration of the various devices is done by appropriate jumper settings on the
demonstration board, and all necessary I/O interface connectors as applicable for each
signal format are provided. Standard interconnects available in the market can be used to
evaluate the demonstration board.
The demonstration board has a 16 character x 2 line backlit LCD which shows the selection
status and a preprogrammed microcontroller senses all the control signals and
appropriately displays it on the LCD.
The demonstration board may be powered by the 9 V adapter supplied or by a standard 9V
adapter with a current capacity of at least 500 mA. The source need not be regulated. On
board regulators supply +5 V and +3.3 V as required.
To summarize, the STEVAL-CCH002V1 serves to demonstrate the following:
■
STMAV335 analog video switch
■
STMAV340 analog video switch
■
STHDMI002A HDMI switch
■
STDVE003A HDMI switch with equalizer/buffer
■
TSH343 analog buffer
■
TSH72 analog buffer
■
ST4300 I2C buffer
■
Various ESD protection devices in the signal I/O ports
The board also demonstrates to a large extent, the recommended PCB layout in end
applications utilizing these devices. Especially critical layout aspects in high-speed HDMI
bus have been carefully addressed in this demonstration board.

The various input/output connectors
Industry-standard connectors with appropriate genders have been provided on the board for
the various video formats supported. Standard interconnects available on the market may
be used during evaluation of the devices. However, the quality of the cables should be
ensured so as not to introduce artifacts within the signal, resulting in apparent degradation
in performance.
2.1.1
VGA I/O
Standard 15-pin female type shell connectors have been provided on the board for the VGA
in/outs. These are similar to PC analog monitor video connectors.

RESET button
The RESET button actually resets the processor in case it gets "hung up". It does NOT
affect the functionality of the demonstration board, except that the display might become
irrelevant for a moment, after recovering from a RESET.

DC supply socket
A standard adaptor socket has been provided as a power inlet port for the demonstration
board. It is polarity protected to accept a center positive adaptor, e.g. the one supplied with
the demonstration board.

The jumpers
There are several jumpers on the board, some of which determine demonstration board
functionality, some may be left as it is, or may be used for signal tracing/factory debugging.
We will start with the essential ones, case by case, as required for demonstrating the
various functions of the demonstration board.
