DATASHEET FN7867 TW6869 Rev. 2.00 Sept 26, 2016 8-in-1 Video Decoders with PCI Express Media Bridge The TW6869 is a highly integrated solution that Audio Codecs supports multi-channel video and audio capture via Integrated eight audio ADCs PCIe x1 interface for PC DVR system and video 8/16 bit audio word length analytic application. It contains high quality eight- Sample audio with 8/16/32/44.1/48kHz channel NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital DMA Controller component YCbCr data, and utilize adaptive 4H comb Highly-efficient DMA design can support up to filter for separating luminance and chrominance to 8 real time D1 video and 8 real time audio reduce cross noise artifacts. channels, or up to 32 non-real- time video with optimization of full PCIex1 bandwidth TW6869 contains a high performance proprietary Multiple video format output support: DMA controller that fully optimizes the utilization of UYVY/Y422, YUYV/YUY2, IYU1/Y411, Y41P, PCIe x1 bandwidth and enables it to transfer video YUV420, RGB555 and RGB565 and audio data at a high throughput rate that closely Integrated internal video and audio generator approaches the theoretical limit of PCIex1 interface. TW6869 is able to simultaneously decode and simplifies system test and development transfer 8 real time D1 video, or up to 32 channel non- Built-in motion detection engine for each real time D1, plus 8 channel audio. video channel Hardware-friendly design enables smooth TW6869 decreases the complexity and workload of data transfer and virtually eliminates client-side software development, and significantly unwanted big-block data jamming among PC reduces the strains on PC hardware and resources. devices, resulting in optimized PC internal TW6869 also includes a software development kit bandwidth consumption (SDK) with Windows and Linux compliant drivers and reference application software.
