Receive Loss of Signal Output Indicator
This output pin indicates Loss of Signal (LOS) Defect condition for the corre-
sponding channel.
"Low" - Indicates that the corresponding Channel is NOT currently declaring the
LOS defect condition.
"High" - Indicates that the corresponding Channel is currently declaring the LOS
defect condition.

OTE
:
The Receive Section of a given channel will declare the LOL condition
anytime the frequency of the Recovered Clock (RCLK) signal differs
from that of the reference clock programmed for that channel by 0.5%
or more.

Receive Positive Data Output
The function of these output pins depends upon whether the channel has been
configured to operate in the Single-Rail or Dual-Rail Mode.
Dual-Rail Mode - Receive Positive Polarity Data Output
If the channel has been configured to operate in the Dual-Rail Mode, then all
positive-polarity data will be output via this pin. The negative-polarity data will
be output via the corresponding RxNEG_n pin. In other words, the Receive
Section of the corresponding Channel will pulse this output pin "High" for one
period of RCLK_n anytime it receives a positive-polarity pulse via the RTIP/
RRING input pins.
The data output via this pin is updated upon the active edge of RxCLK_n output
clock signal.
Single-Rail Mode - Receive Data Output
In the Single-Rail Mode, all Receive (or Recovered) data will be output via this
pin.
The data output via this pin is updated upon the active edge of the RCLK_n
output clock signal.
