Ultra-low power consumption (431.88mW typical) 128-pin LQFP package description

The TW2867 includes four high-quality NTSC/PAL/SECAM video decoders that convert into digital composition of analog composite video signals for YCbCr data security applications. Each channel contains a 10-bit ADC and patented clamping circuitry and a gain controller, and uses a 4H comb filter to separate brightness and chromaticity to reduce crossover noise unnaturally. TW2867 features image enhancement technologies such as IF compensation filters, CTI, and programmable peaks. The TW2867 also contains audio codecs with five audio analog-to-digital converters and one digital-to-analog converter. A built-in audio controller can generate a recording/mix for playback and accept digital input digital output.
