Rev. 1.00
Aug 1, 2017 4-Channel Video Decoders and Audio Codecs and
Video Encoder for Security Application The TW2865 includes four high quality NTSC/PAL/SECAM video decoders that convert analog composite video
signal to digital component YCbCr data for security application. Each channel contains 10 bit ADC and proprietary
clamp and gain controllers and utilizes 4H comb filter for separating luminance & chrominance to reduce cross
noise artifacts. The TW2865 adopts the image enhancement techniques such as IF compensation filter, CTI and
programmable peaking. TW2865 also includes one NTSC/PAL video encoder with two 10bit DAC’s to support CVBS
and YC output. The TW2865 also includes audio CODEC which has five 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
