TRANSMITTER SIGNAL GROUND
TRANSMITTER POWER SUPPLY
Figure 3. Pin Out Diagram.
Pin Descriptions:
Pin 1 Receiver Signal Ground V
EE
RX:
Directly connect this pin to the
receiver ground plane.
Pin 2 Receiver Power Supply V
CC
RX:
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
CC
RX
pin.
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.
Pin 6 Transmitter Power Supply
V
CC
TX:
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
CC
TX
pin.
Pin 7 Transmitter Signal Ground
V
EE
TX:
Directly connect this pin to the
transmitter ground plane.
Pin 8 Transmitter Disable T
DIS
:
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.
Pin 10 Transmitter Data In Bar TD-:
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.
