Connection Diagram
RECEIVER SIGNAL GROUND
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 dc receiver
power supply filter circuit. Locate the power supply
filter circuit as close as possible to the V
the filter circuit should not cause V
minimum 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 LVTTL
input on an upstream circuit, such as Signal Detect in-
put or Loss of Signal-bar.
Pin 4 Receiver Data Out Bar RD-:
Output internally biased and ac coupled.
Pin 5 Receiver Data Out RD+:
Output internally biased and ac coupled.
Pin 6 Transmitter Power Supply V
Provide +3.3 V dc via the recommended dc 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+:
Input internally terminated and ac coupled.
Pin 10 Transmitter Data In Bar TD-:
Input internally terminated and ac coupled.
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.
Package Grounding Tabs
Connect four package grounding tabs to signal ground.
