TW6864/TW6868
Multi-Channel PCIe Video Capture IC with
Built-in 4-Channel Video and Audio Decoder
The TW6864/8 is a highly integrated single-chip solution that supports multi-channel real time video and audio capture via PCIe x1 interface for
PC DVR applications. It contains four high quality NTSC/PAL/SECAM video decoder that converts analog composite video signal to digital compo-
nent YCbCr data, and utilizes an adaptive 4H comb filter for separating luminance and chrominance to reduce cross noise artifacts. TW6864/8
contains a high performance proprietary DMA controller that fully utilizes the PCIe x1 bandwidth, enabling it to transfer video and audio data at
optimal throughput rate.
TW6864/8 has the versatility to support a wide variety of video applications, including decoding and transferring 4 channel real-time D1 video, or
up to 16 channel non-real-time video simultaneously. It supports multiple video display formats such as D1, half D1 and CIF. By implementing
Intersil Techwell’s advanced proprietary video-switching technology, TW6864/8 possesses industry-leading video-locking speed in non-real-time
switching mode. In addition, coupled with an external Intersil Techwell four-channel decoder, TW6868 can transfer up to 8 channels of real-time
D1 video and 9 channels of audio output.
