2. 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.

The DM5885 includes two SD mixers and one HD

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.
