Connection Diagram
Pin Descriptions:
Pin 1 Receiver Signal Ground V
Directly connect this pin to the receiver ground plane.
Pin 2 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
ter circuit should not cause V
specification.
Pin 3 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 input on an upstream circuit,
such as Signal Detect input or Loss of Signal-bar.
Pin 4 Receiver Data Out Bar RD-:
PECL logic family. Output internally biased and ac
coupled.
Pin 5 Receiver Data Out RD+:
PECL logic family. Output internally biased and ac
coupled.
Pin 6 Transmitter Power Supply V
Provide +3.3 V dc via the recommended transmitter
power supply filter circuit. Locate the power supply fil-
ter circuit as close as possible to the V

Pin 7 Transmitter Signal Ground V
Directly connect this pin to the transmitter signal
ground plane.
Pin 8 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 9 Transmitter Data In TD+:
PECL logic family. Internal terminations are provided
(Terminations, ac coupling).
Pin 10 Transmitter Data In Bar TD-:
Internal terminations are provided (Terminations, ac
coupling).
Mounting Studs/Solder Posts
The two mounting studs are provided for transceiver
mechanical attachment to the circuit board. It is rec-
ommended that the holes in the circuit board be con-
nected to chassis ground.
