Receiver Specifications

LP-Serial receiver electrical and timing specifications are stated in the text and tables of this section.

The receiver input impedance results in a differential return loss better than 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 Ohm resistive for common mode.
