General Description
The CH7302/CH7303 is a Display Controller device which
accepts a digital graphics input signal, and encodes and
transmits data through a DVI link (DFP can also be
supported), VGA port (analog RGB) or an HDTV port
(YPrPb). The device accepts data over one 16-bit wide
variable voltage data port which supports different data
formats including RGB and YCrCb.
The device is able to generate and insert synchronization
signals for analog HDTV interface standards. Color space
conversion from RGB and YCrCb to YPrPb is supported
The DVI processor includes a low jitter PLL for
generation of the high frequency serialized clock, and all
circuitry required to encode, serialize and transmit data.
The CH7302/CH7303 is able to drive a DVI display at a
pixel rate of up to 165MHz, supporting UXGA resolution
displays. No scaling of input data is performed on the
data output to the DVI device.
In addition to DVI encoder and HDTV modes, bypass modes
are included which output VGA style analog RGB for use as
a CRT DAC supporting graphics standards up to UXGA.
Color space conversion from YCrCb to RGB is supported
in both DVI and VGA bypass modes.

... CHRONTEL 2.0 Functional Description 2.1 TV Output Operation The CH7302/CH7303 can be selected to operate in one of several bypass modes for driving monitors requiring component video signals (HDTV, multi-sync monitors, etc.). All modes make use of the same set of DACs, and therefore cannot be used simultaneously. Table 2 describes the possible operating modes. A ‘p’ following a number in the Input Scan Type column indicates a progressive scan (non-interlaced) input where the number indicates the active number of lines per frame. An ‘ ...

... CHRONTEL 3.0 Register Control The CH7302/CH7303 is controlled via a serial control port. The serial bus uses only the SC clock to latch data into registers, and does not use any internally generated clocks so that the device can be written to in all power down modes. The device should retain all register values during power down modes. For details of CH7302/CH7303 registers read/write operation, please see AN-61 ...
