DVI/HDMI chip - MS3814
Equalizes FR-4 PCB microstrip line and high-frequency cable loss: can compensate for 15dB cable loss at 825MHz frequency.
At 1650Mbps rate, for a channel loss of 0~15dB@825MHz, the jitter margin is less than 0.25UIPP
input terminal 50Ω (each end to VCC) ±10%
output driver compatible with DVI/HDMI1.3
output amplitude: differential 1050mVPP
ENABLE pin controls to select normal operation mode or power-down mode
LEVEL pin selects different output currents to accommodate with or without back-termination resistors
Product Introduction
MS3814is aTMDSequalization/driver chip, used to compensateFR-4andcable toDVI/HDMIconnector loss. Provides fully compliantDVI/HDMI TMDSrequired output. The chip can also be used forDVI/HDMIcables to extend transmission distance, improvejitter margin of the cable channel at the high connector receiving side. On-chipTMDSdriver can either workin typicalDVI/HDMIcurrent mode, at this time the differential output terminal is not connected to back-termination elecresistance; it can also work in increased output current50%mode, at this time the differential output terminal acrossconnect200Ωresistor, to obtain10dBreturn loss of. TypicalDVI/HDMI output driverdriver exists connector and high impedanceDVI/HDMIreflection issues between outputs. Can selectoutput current (LEVEL pin control) provides back-termination connection options (e.g., differential outputoutput terminal across200Ωresistor), effectively reducing reflection, while reducing output common-mode offsetto a minimum.
