OCTAL T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR

MONITOR_3 Protected Monitoring: With protected monitoring enabled,
the receiver 7 inputs at RTIP_7 and RRING_7 are internally
connected to one of the other seven transmit and receive
channels.Receiver 7 recovers the input data and clock and
output them to RPOS_7/RNEG_7 and RCLK_7 respectively. In
addition, the data to be monitored can be routed to TTIP_7 and
TRING_7 by means of activating Remote Loop-Back for chan-
nel 7.
With MONITOR_[3:0] bits set to “0”, the Protected Monitoring
feature is disabled and the XRT83L38 is configured as an octal
line transceiver.
