TDA 6920
Wireless Components
Specification, August 1999
2.1 Overview
The TDA 6920 switches 7 video input sources to 5 outputs. Each output can be
switched to only one input, but one input can be switched to all outputs. The
C-input may be combined with one CVBS input as Y for Y+C (S-VHS)
operation. Y+C operation is selected by bus.
