DATASHEET

TW2867C

4-Channel Video Decoders and Audio Codecs For

Security Applications

The TW2867 includes four high quality

NTSC/PAL/SECAM video decoders that convert

analog composite video signal to digital

component YCbCr data for security applications.

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 TW2867 adopts

the image enhancement techniques, such as IF

compensation filter, CTI and programmable

peaking. The TW2867 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.
