RX Polarity Control
Overview
The GTP receiver can invert incoming data using the RX polarity control function. This
function is useful in designs where the RXP and RXN signals can be accidentally connected
in reverse. The RXPOLARITY port is driven High to invert the polarity of incoming data.
Ports and Attributes
Table 7-17 defines the RX polarity ports.
There are no attributes in this section.
Description
The RX Polarity port is used to invert the polarity of incoming data. Driving this port High
causes the RXN pin to be treated as RXP and the RXP pin to be treated as RXN.
