EP91R1S is a 6GHz HDMI 2.0b 1-IN 1-OUT Repeater with integrated Equalizer and Jitter Clean Circuit. The chip uses Re-Sample and Re-Drive architecture which re-samples data at the receiver side and re-drive data at the transmitter side. This architecture will not pass through noise from inputs to output and hence provides reliable transmission. Besides, the Jitter Clean Circuit provides the jitter-free output for extending the Cable Length. The chip also supports on-chip EDID RAM and programmable passive/active DDC switches to lower down system cost. This chip also integrates with an e-Flash MCU to make the user very easy to use.
