Introduction
STMAV335 has three sets of 3 to 1 switches that are well suited for switching analog video
signals on the back panel of television sets or monitors. Below is a diagram of an
STMAV335 typical application configuration:
Typical display unit back panel video input
VIDEO RECEIVER
YPbPr OR RGB OR CVBS&S-VIDEO
STM A V 335
YPbPr
RGB CVBS&S-VIDEO
As illustrated above, STMAV335 is used to switch one of the three video input sets to the
video receiver. Depending on the SEL inputs, YPbPr, RGB, or CVBS&S-VIDEO signals will
be directed to the video receiver. Hence less IO is required at the video receiver to handle
the many different video signal inputs on the display unit back panel.
Ultimately, integrating STMAV335 to the system will result in a straightforward system
design and overall cost reduction.
