1. General Description

The Lontium LT8641UX HDMI2.0 Switch features a 4:1 switch compliant to HDMI2.0/1.4 specification, max 6Gbps high speed data rate, adaptive equalization RX input and pre-emphasized TX output to support long cable application, no XTAL and 1.2V power supply on board to save BOM cost, internal TX lane swap for flexible PCB routing .
LT8641UX HDMI2.0 Switch automatically detect the cable loss, and adaptively optimize the equalization setting . The  CDR cleans the input  data jitter,  make it suitable for long cable and cascade application. It support RX termination resistor calibration to further improve signal integrity.
LT8641UX support DDC/SCDC compliant to HDMI2.0/1.4 specification . The integrated DDC and HPD switches further lower the cost of system manufacture, and simplify the routing on the system board .
