Analog Front End (AFE)
The FLI8668 chip has a flexible Analog Front End (AFE) with 13 configurable inputs. These
13 inputs can be shared across two configurable paths: V1 and V2. Either of these paths can
be used as Main or PIP channels. The 13 configurable inputs can be routed through an
analog multiplexer before the Analog to Digital Converters (ADCs) and decoders in V1 and V2.
These integrated features eliminate the need for any device between the input connector and
the Analog input pin of the FLI8668 beyond de-coupling capacitors.

The figure above depicts the data path for the AFE and decoder blocks on V1 and V2 paths in
FLI8668. The data path selects whether the data follows the Main Video Channel or PIP video
channel.
