SAA7160

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 I²S-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.
