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.
