General Description The DM5885 is a 4-channel video decoder which converts 4 channels of 6.5 MHz analog CVBS signals to 4 channels of digital 27 MHz CCIR656 signals. The DM5885 integrates two internal PLLs, and decodes 720H videos using the same (27MHz) external clock source. The DM5885 also features a patented fast switch function. With the fast switch function, the DM5885 can decode up to 8 analog CVBS with little frame rate loss. mixer. Each SD/HD mixer can multiplex up to 4 video sources. In addition to two SD CCIR656 outputs or one HD SMPTE 274M output, the DM5885 mixer can output four D1 videos through one TDM4 interface. The mixers support image mirror and H partition functions. Both interlaced and progressive digital video outputs are supported. The DM5885 also includes five audio ADCs and one audio DAC. The DM5885 includes two SD mixers and one HD 2.
