LP-Serial receiver electrical and timing specifications are stated in the text and tables of this section.
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
components are included in this requirement. The reference impedance for return loss measurements is
100 Ohm resistive for differential return loss and 25-Ω resistive for common mode.
