Transmit Fault alarm out-
put. Indicates that the laser
has been automatically
shut off due to a fault in the
TX laser circuit. High = TX
Fault. Fault may be cleared
by cycling DC power, or by
strobing the RESET_L in-
put.
Transmit Bias Monitor
alarm output. Indicates that
the bias current of the TX
laser is currently outside
normal operating limits.
High = TX Bias outside lim-
its.

Master Reset input. A Low
level resets the TX Mux
and Laser Driver. RESET_L
must be held low for at
least 6 millisec. Pulled high
through a 1 k

Parallel Output Data at
622.08 Mb/s from the Re-
ceiver, aligned to the Parallel
Output Clock (RXCLKP/N).
RXDATAP/N[3] is the Most
Significant Bit, and is the first
bit received in the incoming
OC-48 serial data stream.
RXDATAP/N[3:0] is updated
on the falling edge of RX-
CLKP. All data outputs are
forced to zero level under
Loss Of Signal or Loss Of
Synchronization conditions.
DC coupled outputs. Internal-
ly terminated.

Parallel Output Clock from
the Receiver at 622.08 MHz.
This clock is aligned to the
RXDATAP/N[3:0] parallel out-
put data. RXDATAP/N[3:0] is
updated on the falling edge
of RXCLKP. Clock output is
continuous under Loss Of
Signal or Loss Of Synchroni-
zation conditions. DC cou-
pled output. Internally
terminated.
Receive Loss Of Signal alarm
output. A High output level
indicates RX input power is
below the sensitivity level of
the receiver (high BER condi-
tion).

57
Receive Loss Of Synchroni-
zation alarm output. A High
output level indicates that
the receive Clock Recovery
unit has lost synchronization,
due to either very low RX in-
put power level, or input data
rate outside of frequency tol-
erance.
Receive power monitor
output. A voltage output
which is directly proportional
to the optical RX input
power.

Line Loopback Enable input. A
Low level enables Line Loopback
mode. When active, the RX inputs
to the Transceiver IC will be routed
directly to the TX outputs. Pulled
high through a 1 k
resistor.
Diagnostic Loopback Enable input.
A Low level enables Diagnostic
Loopback mode. When active, the
TX outputs of the Transceiver IC
are routed directly to the RX in-
puts. Pulled high through a 1 k

Reference Loop Time Enable in-

ence Loop Time. When active, a
divide-by-4 version of the PO-
CLKP/N output of the RX is used as
the reference clock input to the TX.
Pulled low through a 1 k
resistor.
Serial Loop Time Enable input. A
High level enables Serial Loop
Time. When active, the recovered
high-speed clock (RSCLKP/N) from
the RX section is used in place of
the synthesized transmit clock.
Pulled low through a 1 k

Ground connection for both
signal and chassis ground
on the transponder. The
blade contact of the 60 pin
interface connector is tied to
ground in the transponder.
Therefore, the blade of the
user‘s mating connector
should be connected to
ground, as well.
