DESCRIPTION
The AVPro
switching IC that supports an input/output port, an
input only port, and an output only port. The device
includes multiplexers that allow the inputs to be
routed to the outputs in various configurations.
Additional outputs are provided to drive an external
RF modulator. The video outputs of the multiplexers
are buffered to drive 137-ohm loads. The audio
outputs are buffered to provide 2 Vrms output into
600 ohms. The 5002C has features optimized for
Canal+ satellite receiver applications, but it can also
be used in other applications that require control of
multiple audio and video sources.
