Connection Diagram
TRANSMITTER SIGNAL GROUND
Pin Descriptions:
Pin 1 Receiver Signal Ground V
Directly connect this pin to the receiver ground plane.
Pin 2 Receiver Data Out RD:
See recommended circuit schematic, Figure 4.
Pin 3 Receiver Data Out Bar RD:
See recommended circuit schematic, Figure 4.
Pin 4 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 5 Receiver Power Supply V
Provide +5 V dc via the recommended transmitter power
supply filter circuit. Locate the power supply filter circuit
as close as possible to the V

Mounting Studs
The mounting studs are provided for mechanical attach-
ment to the circuit board. They are embedded in the
nonconductive plastic housing and are not tied to the
transceiver internal circuit and should be soldered into
plated-through holes on the printed circuit board.
