Function
Receive Data Output/Positive
Received data at RL1/2 is sent on RDOP/
RDON in NRZ format to the framer
interface. Clocking of data is done with the
rising or falling edge of RCLK(1:4),
selected by bit LIM4.RPE. RDOP/RDON
are set low if a loss-of-signal alarm is
detected.
The source of the received data is selected
by bit LIM2.RD(1:0).
LIM2.RD(1:0) = 00: Data recovered by the
DPLL is AMI/HDB3/B8ZS decoded and
output on RDOP; RDON is not defined.
LIM2.RD(1:0) = 01: Dual-rail data
recovered by the DPLL, not AMI/HDB3/
B8ZS decoded, is output on RDOP/RDON.
LIM2.RD(1:0) = 10: Sliced data, not
recovered by the DPLL is output on RDOP/
RDON. A “1” on RDOP corresponds to a
positive pulse on RL1/RL2. A “1” on RDON
corresponds to a negative pulse on RL1/
RL2.
Receive Data Output/Negative
LIM1.RDON(1:0) = 00 (see above)
Bipolar Violation Indication
LIM1.RDON(1:0) = 01
System Clock Output
LIM1.RDON(1:0) = 10
System Clock Input
LIM1.RDON(1:0) = 11
Read clock for jitter attenuater buffer if
internal DCO is not used (see
