DESCRIPTION
The AVPro
廬
5002CL device is an audio/video 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鈩?/div>
loads. The audio outputs are buffered to provide 2
Vrms output into a 600鈩?load. The 5002CL 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.
