1. Description

The LT8631UXE HD-DVI2.0/1.4 Switch features a 3:1
switch compliant with HD-DVI2.0/1.4 specification, max 6Gbps high speed data rate, adaptive equalization RX input and pre-emphasized TX output to support long cable application, no XTAL on board to save BOM cost.
LT8631UXE HD-DVI2.0/1.4 Switch automatically detects the cable loss, and adaptively optimize the equalization setting. It supports RX termination resistor calibration to further improve signal integrity.
LT8631UXE support DDC/ACDC (Auxiliary and Control Data Channel) compliant to HD-DVI2.0/1.4 specification. The integrated DDC and HPD switches further lower the cost of system manufacture, and simplify the routing on the system board.
