Figure 5 - Pin Out Diagram (Top View)
Pin Descriptions:
Pin 1 Photo Detector Bias, VpdR:
Pin 1 must be connected to VCC for the receiver to work.
This pin enables monitoring of photo detector bias current. It
must be connected directly to V
a resistor (Max 200 R) for monitoring photo 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 sup-
ply filter circuit. Locate the power supply filter circuit as close
as possible to the V
not cause V
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
low voltage TTL input on an upstream circuit, such as Signal
Detect input or Loss of Signal-bar.
Pin 9 Receiver Data Out Bar RD-:
No internal terminations are provided. See recommended
circuit schematic.
Pin 10 Receiver Data Out RD+:
No internal terminations are provided. See recommended
circuit schematic.
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”

Pin 15 Transmitter Data In Bar TD-:
No internal terminations are provided. See recommended

Pin 17 Laser Diode Bias Current Monitor - Negative End B
The laser diode bias current is accessible by measuring the
voltage developed across pins 17 and 18. Dividing the volt-
age by 10 Ohms (internal) will yield the value of the laser bias
current.
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 measur-
ing the voltage developed across pins 19 and 20. The voltage
across a 200 Ohm internal resistor between pins 19 and 20
will be proportional to the photo current.
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 me-
chanical attachment to the circuit board. It is recommended
that the holes in the circuit board be connected to chassis
ground.
Package Grounding Tabs
Connect four package grounding tabs to signal ground.
