Figure 3. Pin Out 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
circuit as close as possible to the V
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 fault
condition indicated by a logic “0” output.
This Signal Detect output can be used to drive a PECL
input on an upstream circuit, such as Signal Detect
input or Loss of Signal-bar.
Pin 4 Receiver Data Out Bar RD-:
No internal terminations are provided. See
recommended circuit schematic.
Pin 5 Receiver Data Out RD+:
No internal terminations are provided. See
recommended circuit schematic.

Directly connect this pin to the transmitter ground
plane.
Pin 8 Transmitter Disable T
No internal connection. Optional feature for laser based
products only. For laser based products 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+:
No internal terminations are provided. See
recommended circuit schematic.

No internal terminations are provided. See
recommended circuit schematic.
Mounting Studs/Solder Posts
The mounting studs are provided for transceiver
mechanical attachment to the circuit board. It is
recommended that the holes in the circuit board be
connected to chassis ground.
