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:

DAC Power Supply
These pins supply the 5V power to CH7013A’s internal DAC’s.
DAC Ground
These pins provide the ground reference for CH7013A’s internal DACs.
For information on proper supply de-coupling, please refer to the
Application Information section.
Digital Supply Voltage
These pins supply the 3.3V power to the digital section of CH7013A.
Digital Ground
These pins provide the ground reference for the digital section of
CH7013A, and MUST be connected to the system ground to prevent
latchup.
