MS
Mounting Studs. The mounting studs are provided for transceiver
mechanical attachment to the circuit board. They may also provide an
optional connection of the transceiver to the equipment chassis
ground.
NA
1VPD
Photodetector Bias Input. This lead supplies bias for the PIN photo-
detector diode
NA
2VEER
Receiver Signal Ground.
NA
3VEER
Receiver Signal Ground.
NA
4CLK–
Received Recovered Clock Out. The rising edge occurs at the rising
edge of the Received Data output. The falling edge occurs in the mid-
dle of the Received Data baud period.
CML
5CLK+
Received Recover Clock Out. The falling edge occurs at the rising
edge of the Received Data output. The rising edge occurs in the mid-
dle of the Received Data baud period.
CML
6VEER
Receiver Signal Ground.
NA
7VCCR
Receiver Power Supply.
NA
8SD
Signal Detect.
Normal operation: logic 1 output.
Fault condition: logic 0 output

TD–
Transmitter DATA In. See TD+ pin for terminations.
LVPECL/CML
16
NIC
No Internal Connection.
NA
17
BMON
Laser Diode Bias Current Monitor, Negative End. The laser bias
current is accessible as a dc voltage by measuring the voltage devel-
oped across pins 17 and 18.
NA
18
BMON+
Laser Diode Bias Current Monitor, Positive End. Optional feature;
if not used, do not connect. See pin 17 description.
NA
19
PMON
Laser Diode Optical Power Monitor, Negative End. Optional fea-
ture; if not used, do not connect. The back-facet diode monitor cur-
rent is accessible as a voltage proportional to the photocurrent
through a 200
resistor between pins 19 and 20.
NA
20
PMON+
Laser Diode Optical Power Monitor, Positive End. Optional fea-
ture; if not used, do not connect. See pin 19 description.
