Detailed Description

14. DVI Codec

The ML605 features a DVI connector (P3) to support an external video monitor. The DVI circuitry utilizes a Chrontel CH7301C (U38) capable of 1600 X 1200 resolution with 24-bit color. The video interface chip drives both the digital and analog signals to the DVI connector. A DVI monitor can be connected to the board directly. A VGA monitor can also be connected to the board using the supplied DVI-to-VGA adaptor. The Chrontel CH7301C is controlled by way of the video IIC bus.

The DVI connector (Table 1-17) supports the IIC protocol to allow the board to read the monitor's configuration parameters. These parameters can be read by the FPGA using the DVI IIC bus (see “15. IIC Bus,” page 42).
