• Manufacturer Part Number: TW6864-LB2-GR
• Description: 4 Channel Multi-Standard Video And Audio Decoder With PCIe I
• Manufacturer: Intersil

The TW6816 is a highly integrated single-chip solution that supports multi-channel real time video and audio capture via PCI interface for PC DVR
applications. It contains four high quality NTSC/PAL/SECAM video decoder that converts analog composite video signal to digital component
YCbCr data, and utilizes an adaptive 4H comb filter for separating luminance and chrominance to reduce cross noise artifacts. TW6816 contains a
high performance proprietary DMA controller that fully utilizes the PCI bandwidth, enabling it to transfer video and audio data at optimal
throughput rate.
TW6816 has the versatility to support a wide variety of video applications, including decoding and transferring 4 channel real-time D1 video, and
supporting multiple video display formats such as D1, half D1 and CIF. In addition, TW6816 can support up to 16 channel non real-time D1 video.
