TW2816
4 Channel Video Decoders
For Security Applications
* Pin to pin compatible with the TW2815
The TW2816 includes four high quality NTSC/PAL video decoders that
convert analog composite video signals to digital component YCbCr data
for security applications. The TW2816 contains four 10 bit ADCs and
proprietary clamp and gain controllers and utilizes 4H comb filters for
separating luminance & chrominance to reduce cross noise artifacts. The
TW2816 adopts image enhancement techniques such as IF compensation
filter, CTI and programmable peaking.
