4-Channel Analog Video Decoders and Analog Video
Encoder for Automotive Applications
TW9966
Features
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.
