3.19.5.4.2 DC serial RapidIO receiver specifications
LP-Serial receiver electrical and timing specifications are stated in the text and tables of
this section.
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) x (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-Ω resistive for
differential return loss and 25-Ω resistive for common mode.
This table defines the receiver DC specifications for serial RapidIO operating at 2.5 and
3.125 GBaud.
