4-Channel Video Decoders and Audio Codecs
for Security Applications FN7735
Rev. 1.00
May 19, 2017 The TW2815 includes four high quality NTSC/PAL video decoders that convert analog composite video signal to
digital component YCbCr data for security application. The TW2815 contains four 10-bit ADC and proprietary clamp
and gain controllers and uses 4H comb filter for separating luminance & chrominance to reduce cross noise artifacts.
The TW2815 adopts the image enhancement techniques such as IF compensation filter, CTI , and programmable
peaking. The TW2815 also includes audio CODEC which has four audio Analog-to-Digital converters and one
Digital-to-Analog converter. A built-in audio controller can generate digital outputs for recording/mixing and accepts
digital input for playback. Features
