Disable Digital LOS Detector - Channel_n:
This READ/WRITE bit-field is used to either enable or dis-
able the Digital LOS (Loss of Signal) Detector within
Channel_n, as described below.
0 - Enables the Digital LOS Detector within Channel_n.
NOTE: This is the default condition.
1 - Disables the Digital LOS Detector within Channel_n.
NOTE: This bit-field is only active if Channel_n has been
configured to operate in the DS3 or STS-1 Modes.
0
Disable Analog LOS Detector - Channel_n:
This READ/WRITE bit-field is used to either enable or dis-
able the Analog LOS (Loss of Signal) Detector within
Channel_n, as described below.
0 - Enables the Analog LOS Detector within Channel_n.
NOTE: This is the default condition.
1 - Disables the Analog LOS Detector within Channel_n.
NOTE: This bit-field is only active if Channel_n has been
configured to operate in the DS3 or STS-1 Modes.

Receive Clock Invert Select - Channel_n:
This READ/WRITE bit-field is used to select the edge of
the RCLK_n output that the Receive Section of Channel_n
will use to output the recovered data via the RPOS_n and
RNEG_n output pins, as described below.
0 - Configures the Receive Section (within the correspond-
ing channel) to output the recovered data via the RPOS_n
and RNEG_n output pins upon the rising edge of RCLK_n.
1 - Configures the Receive Section (within the correspond-
ing channel) to output the recovered data via the RPOS_n
and RNEG_n output pins upon the falling edge of RCLK_n.
