TW6869 Datasheet 8-in-1 Video Decoders

Manufacturer: Intersil (now Renesas)

Overview

8-in-1 Video Decoders with PCI Express Media Bridge TW6869 The TW6869 is a highly integrated solution that supports multi-channel video and audio capture via PCIe x1 interface for PC DVR system and video analytic application.

It contains high quality eightchannel NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital component YCbCr data, and utilize adaptive 4H comb filter for separating luminance and chrominance to reduce cross noise artifacts.

TW6869 contains a high performance proprietary DMA controller that fully optimizes the utilization of PCIe x1 bandwidth and enables it to transfer video and audio data at a high throughput rate that closely approaches the theoretical limit of PCIex1 interface.
