Techwell

The TW2864 is Techwell’s 4th generation 4-in-1 video decoder and audio

codec for security surveillance applications. The device includes four high

quality NTSC/PAL video decoders that convert analog composite video

signal to digital component YCbCr data. The TW2864 contains four 10-bit

ADCs and proprietary clamp and gain controllers and utilizes adaptive 4H

comb filter for separating luminance & chrominance to reduce cross noise

artifacts. The TW2864 adopts the image enhancement techniques such as

IF compensation filter, CTI and programmable peaking. The TW2864 also

includes audio codec which has four audio ADCs and one audio DAC. A

built-in audio controller can generate digital outputs for recording/mixing

and accepts digital input for playback.
