DESCRIPTION
The AVPro^® 5303B device is a universal three input A/V
switch interface IC designed for TV and general-purpose
A/V applications. The device provides interfaces for
three full sets of TV SCART input signals (Red, Green,
Blue, CVBS, R, L, Fast Blanking, and TV Function) and
also supports SCART SVHS video mode. In addition, the
5303B can be configured to support general-purpose
A/V interface (YPrPb, SVHS, and CVBS) for TVs, DVD
recorders, digital set-top boxes, and PVRs. Video and
audio gains are programmable. All switching and
function settings are controlled via I²C.
