Description

The CH7320 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 CH7320 is able to drive a DFP display at a pixel rate of up to 165MHz, supporting UXGA (1600x1200) resolution displays.

The CH7320 has two DVI output ports that allow two DVI monitors to be switched from a single source. Its connection detection circuitry will automatically route the DVI data stream to a correct DVI port that a monitor is attached to.

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