Analog Front End
The Analog Front End is responsible for selecting and capturing the desired analog input
video stream. Overall application cost is reduced by providing analog switching capabilities for
16 separate analog signals. These signals are re-configurable as different combinations of
composite, S-Video, YPrPb and RGB video streams depending upon the end application.
The Analog Front End directs inputs through an analog multiplexer to anti-alias filters before
the Analog to Digital Converters (ADCs). These integrated features eliminate the need for any
devices between the input connector and the AFE pin connection.
The following figure depicts the data-path for the AFE and Decoder blocks with connections to
the input multiplexer .
