General description

The PNX2000 is a companion IC for use with the Nexperia™

1

digital video home

entertainment engines such as PNX8526 and PNX8550.

The PNX2000 is always used in combination with the PNX3000.

PNX2000 is intended for mid to high-end analog and hybrid TV sets, performing input
decoding of single stream analog audio and single stream analog video signals. In
addition, the PNX2000 is used for decoding and presentation of all audio output streams
in the system.
