Describe

The CH7313A is a Display Controller device, which accepts a digital graphics input signal, encodes and transmits data through a DVI link (DFP can also be supported) with optional HDCP support. The device accepts one channel of RGB data over three pairs of serial data ports.

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 the data. The CH7313A is able to drive a DFP display at a pixel rate of up to 165MHz.

The CH7313A has the ability to become a HDCP rev1.1 Down-stream compliant DVI transmitter by using an internal HDCP key containing the proper device keys that can be obtained from Chrontel, Inc.

CH7313A is pin to pin compatible with CH7307C DVI Transmitter and CH7312A.
