Receiver On
Hardware Mode Only
This pin is used to enable the receivers for all channels. By default, the receivers
are turned ON in hardware mode. To turn the receivers OFF, pull this pin "Low".

Receive Loss of Signal
When a receive loss of signal occurs according to ITU-T G.775, the RLOS pin will go
"High" for a minimum of one RCLK cycle. RLOS will remain "High" until the loss of
signal condition clears. See the Receive Loss of Signal section of this datasheet for
more details.
N
OTE
:
This pin can be used for redundancy applications to initiate an automatic
switch to a backup card.

Receive Clock Output
RCLK is the recovered clock from the incoming data stream. If the incoming signal
is absent or RTIP/RRING are in "High-Z", RCLK maintains its timing by using an
internal master clock as its reference. RPOS/RNEG data can be updated on either
edge of RCLK selected by RCLKE.
N
OTE
:
RCLKE is a global setting that applies to all 8 channels.

RNEG/LCV_OF Output
In dual rail mode, this pin is the receive negative data output. In single rail mode,
this pin is a Line Code Violation / Overflow indicator Indicator. If LCV is selected by
software and if a line code violation, a bi-polar violation, or excessive zeros occur,
the LCV_OF pin will pull "High" for a minimum of one RCLK cycle. LCV_OF will
remain "High" until there are no more violations. However, if OF (Overflow) is
selected, then the LCV_OF pin will pull "High" if the internal LCV counter is satu-
rated. The LCV_OF pin will remain "High" until the LCV counter is reset.

RPOS/RDATA Output
Receive digital output pin. In dual rail mode, this pin is the receive positive data out-
put. In single rail mode, this pin is the receive non-return to zero (NRZ) data output.
