LP-Serial receiver electrical and timing specifications are stated in the text and
Receiver input impedance shall result in a differential return loss better that 10 dB and a common mode
return loss better than 6 dB from 100 MHz to (0.8) × (Baud Frequency). This includes contributions from
on-chip circuitry, the chip package and any off-chip components related to the receiver. AC-coupling
