Receive Negative Data Output/Line Code Violation
The function of these pins depends on whether the XRT75R12D is configured in
Single Rail or Dual Rail mode.
Dual-Rail Mode - Receive Negative Polarity Data Output
In the Dual-Rail Mode, all negative-polarity data will be output via this pin. The
positive-polarity data will be output via the corresponding RxPOS_n output pin.
In other words, the Receive Section of the corresponding Channel will pulse this
output pin "High" for one period of RxCLK_n anytime it receives a negative-
polarity pulse via the RTIP/RRING input pins.
The data output via this pin is updated upon the active edge of the RCLK_n
output clock signal.
Single-Rail Mode - Line Code Violation Indicator Output
In the Single-Rail Mode, this output pin will function as the Line Code Violation
indicator output.
In this configuration, the Receive Section of the Channel will pulse this output
pin "High" for at least one RCLK period whenever it detects either an LCV (Line
Code Violation) or an EXZ (Excessive Zero Event).
The data that is output via this pin is updated upon the active edge of the
RCLK_n output clock signal.

Receive Clock Output
This output pin functions as the Receive or recovered clock signal. All Receive
(or recovered) data will output via the RxPOS_n and RxNEG_n outputs upon
the active edge of this clock signal.
Additionally, if the device/channel has been configured to operate in the Single-
Rail Mode, then the RNEG_n/LCV_n output pins will also be updated upon the
active edge of this clock signal.
