Digital Video Interface
The CH7013A digital video interface provides a flexible digital interface between a computer graphics controller
and the TV encoder IC, forming the ideal quality/cost configuration for performing the TV-output function. This
digital interface consists of up to 16 data signals and 4 control signals, all of which are subject to programmable
control through the CH7013A register set. This interface can be configured as 8, 12 or 16-bit inputs operating in
either multiplexed mode or 16-bit input operation in de-multiplexed mode. It will also accept either YCrCb or RGB
(15, 16 or 24-bit) data formats and will accept both non-interlaced and interlaced data formats. A summary of the
input data format modes is as follows:
