Description

The CH7319 is a Chrontel flat panel display product targeted at PC industry. This transmitter accepts a digital RGB graphics input signal stream from the Intel's Serial Digital Video Output (SDVO) interface, performs digital processing on both data and timing and then transmits DVI signals through a DVI link.

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 CH7319 is able to drive a DFP display at a pixel rate of up to 165MHz, supporting UXGA (1600x1200) resolution displays.

The CH7319 has two DVI output ports that allow two DVI monitors to be switched from a single source. Its detection circuitry will automatically route the DVI data stream to a correct DVI port that a monitor is attached to.

The CH7319 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 which can be obtained from Chrontel, Inc.

CH7319 is pin to pin compatible with CH7315 DVI/HDMI transmitter and CH7320 DVI transmitter.

**CH7319 has been tested with the HDCP Compliance Test Specification version 1.1.
