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.
