Rev 3.00
April 7, 2016 4-Channel Video Decoder and Video Encoder for Automotive Applications
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. Related Literature IF compensation filter for improvement of color
demodulation Color Transient Improvement (CTI) Automatic white peak control Programmable hue, saturation, contrast, brightness and
sharpness Proprietary fast video locking system for non-real-time
application Supports the standard ITU-R BT.656 format or time
multiplexed output with 54/108MHz Supports a two-wire serial host interface UG018, “TW9984AT-NA1-GE-EVAL Evaluation Board User
