概要

The TW9984 includes four high quality NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital component YCbCr data. Each channel contains a 10-bit ADC with application selectable differential or single-ended analog video input options, proprietary clamp and gain controllers and utilizes 4H comb filter for separating luminance and chrominance to reduce cross noise artifacts. The TW9984 adopts the image enhancement techniques, such as IF compensation filter, CTI and programmable peaking. TW9984 also includes an NTSC/PAL video encoder with a 10-bit DAC to support CVBS output.
