6.1.15.1. RX Oversampler
The HDMI design requires oversampling on the RX side in case the data received is below the minimum data rate of the transceiver at 1 Gb/s.
The oversampling factor on the RX is set to 5. For example, a video resolution with TMDS Bit Rates of 742.5 Mb/s should configure the transceiver to operate at 5 times its data rate, which is 3.7125 Gb/s.
