The CV5688 video processing chip is a fully integrated system solution for digital and analog video. 5688 provides images
Capture, process, and display all the key functions required for timing control. Chip features include video ADCs, PLLs, and high quality
Zoom in and out of the zoom engine, motion adaptive interlacing, smart image enhancement, screen display controller, 10-bit DAC
and HDMI TX. All of these features are integrated into a single chip, and the 5688 eliminates the need for multiple system components to simplify the design reduction
cost while maintaining a high degree of flexibility and quality.
