Pin Descriptions:
Pin 1 Photo Detector Bias, VpdR:
This pin enables monitoring of photo detector bias cur-
rent. The pin should either be connected directly to V
C
detector bias current.
Pins 2, 3, 6 Receiver Signal Ground V
Directly connect these pins to the receiver ground plane.
Pins 4, 5 DO NOT CONNECT
Pin 7 Receiver Power Supply V
Provide +3.3 V dc via the recommended receiver power
supply filter circuit. Locate the power supply filter cir-
cuit as close as possible to the V
circuit should not cause V
specification.
Pin 8 Signal Detect SD:
Normal optical input levels to the receiver result in a
logic “1” output.
Low optical input levels to the receiver result in a logic
“0” output.
This Signal Detect output can be used to drive a TTL in-
put on an upstream circuit, such as Signal Detect input or
Loss of Signal-bar.
Pin 9 Receiver Data Out Bar RD-:
PECL logic family. Output internally biased and ac cou-
pled.
Pin 10 Receiver Data Out RD+:
PECL logic family. Output internally biased and ac cou-
pled.
Pin 11 Transmitter Power Supply V
Provide +3.3 V dc via the recommended transmitter
power supply filter circuit. Locate the power supply filter
circuit as close as possible to the V

Pins 12, 16 Transmitter Signal Ground V
Directly connect these pins to the transmitter signal
ground plane.
Pin 13 Transmitter Disable T
Optional feature, connect this pin to +3.3 V TTL logic high
“1” to disable module. To enable module connect to TTL
logic low “0”.
Pin 14 Transmitter Data In TD+:
PECL logic family. Internal terminations are provided (Ter-
minations, ac coupling).
Pin 15 Transmitter Data In Bar TD-:
Internal terminations are provided (Terminations, ac cou-
pling).
Pin 17 Laser Diode Bias Current Monitor - Negative End B
The laser diode bias current is accessible by measuring
the differential voltage developed across pins 17 and 18.
Pin 18 Laser Diode Bias Current Monitor - Positive End B
See pin 17 description.
Pin 19 Laser Diode Optical Power Monitor - Negative End P
The back facet diode monitor current is accessible by mea-
suring the differential voltage developed across pins 19
and 20.
Pin 20 Laser Diode Optical Power Monitor - Positive End P
See pin 19 description.
Mounting Studs/Solder Posts
The two mounting studs are provided for transceiver
mechanical attachment to the circuit board. It is recom-
mended that the holes in the circuit board be connected
to chassis ground.
