DVI Transceiver Module
The SMT939 is a DVI transceiver module SLB expansion card. It is capable of receiving a Single DVI channel running with a maximum clock frequency of 165MHz. The decoded DVI data stream is organised as a 24bit RGB packet with separate syncs and clock. This is fed through level translation buffers to allow the data to be connected to the 2.5V SLB interface header. An onboard EEPROM allows an EDID table to be programmed so that driving hardware can interrogate the DVI input interface.
The SMT939 also has an DVI encoder on the module which supports a single DVI output interface which can run at upto 165Mhz.s939
