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 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.

2. Features

2.1 PCI Express interface SAA7160E and SAA7160ET

I Compliant to PCI Express Base Speciﬁcation 1.0a

I Native PCI Express

N 64-bit address support

N MSI and INT_A message support

I The PCI Express circuit supports isochronous data trafﬁc intended for uninterrupted

transfer of streaming data like video streaming

N x1 PCI Express endpoint device (2.5 Gbit/s)

N Low jitter and bit error rate

I Type 0 conﬁguration space header

N Single BAR; conﬁgurable address range of 17 bits, 18 bits, 19 bits or 20 bits

dependent on application requirements

I DMA write support

N 12 DMA write channels for AV streaming

N Managing up to 8 software buffers per DMA channel

N Buffer size of 2 MB extendable to 4 MB (e.g. HDTV)

N Round-robin arbitration between DMAs

Support overﬂow recovery if PCI Express bandwidth is not granted in the required

amount
