4-Channel Analog Video Decoders and Analog Video Encoder for Automotive Applications

Product Status: Mass Production

OVERVIEW

The TW9966 includes four high quality NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital component YCbCr data for automotive applications. Each channel contains a 10-bit ADC and proprietary clamp and gain controllers and utilizes a 4H comb filter for separating luminance and chrominance to reduce cross noise artifacts. The TW9966 adopts the image enhancement techniques, such as IF compensation filter, CTI and programmable peaking. TW9966 also includes one NTSC/PAL video encoder with two 10-bit DACs to support CVBS and YC output. The TW9966 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.
