4-Channel 960H Video Decoders and Audio Codecs
2. General Description
The DM5866 is a high-end 4-channel video decoder
designed for cameras with Sony’s new 960H CCD
sensor. The DM5866 converts 4 channels of 9/6.5
MHz analog CVBS signals to 4 channels of digital
36/27 MHz CCIR656 signals. The DM5866 integrates
two internal PLLs, and decodes both 960H and 720H
videos using the same (27MHz) external clock source.
The DM5866 also features a patented fast switch
function. With the fast switch function, the DM5866
can decode up to 8 analog CVBS with little frame rate
loss.
The DM5866 also includes five audio ADCs and one
audio DAC. Audio cascade up to 16 channels is also
supported.
