SAA7160
PCI Express based audio and video bridge
Rev. 01 — 25 February 2008
Product data sheet
1. General description
The SAA7160E and the SAA7160ET are PCI Express based audio and video capture
bridges. Both devices provide ports for capturing video streams, transport streams,
program streams and audio streams with audio functionality like I
2
S-bus inputs. The
bridges provide audio and video capture function as required for PCI Express applications
like Microsoft ‘multimedia center’.
The target is to cover a range of performance applications like personal video recording
and PC TV cards.
The SAA7160E and the SAA7160ET are highly integrated circuits for TV insertion inside
PC systems. Additional high-speed programming ports enable high integrated system
solutions for multimedia applications.
