2. General Description

The DM5886 is a high-end 4-channel video decoder

designed for cameras with Sony’s new 960H CCD

sensor. The DM5886 converts 4 channels of 9/6.5

MHz analog CVBS signals to 4 channels of digital

36/27 MHz CCIR656 signals. The DM5886 integrates

two internal PLLs, and decodes both 960H and 720H

videos using the same (27MHz) external clock source.

The DM5886 also features a patented fast switch

function. With the fast switch function, the DM5886

can decode up to 8 analog CVBS with little frame rate

loss.

The DM5886 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 DM5886 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 DM5886 also includes five audio ADCs and one

audio DAC. Audio cascade up to 16 channels is also

supported.
