The CH7206A is a video TV encoder device for DVD applications which accepts a digital video input signal, encodes and transmits data through four 10-bit high speed DACs. The device is able to generate synchronization signals for NTSC and PAL TV standards with CVBS, S-Video outputs, and YPrPb outputs (480i, 576i, 480p and 576p).

The device accepts data over one 12-bit (or 8-bit) wide data port with dual edge clock data transfer for multiplexed data (24 bit or 16 bit) through variable voltage data port which supports 5 different data formats including RGB and YCrCb.

A high accuracy low jitter phase locked loop is integrated to create outstanding video quality. ITU-R BT.656 interlaced video can be input and scan converted to non-interlaced video.

In addition to TV encoder modes, bypass modes are included which perform color space conversion to HDTV standards and generate and insert HDTV sync signals.
