Connection Diagram
Pin Descriptions:
Pin 1 Receiver Signal Ground VEER:
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 VCCR:
Provide +5 V dc via the
recommended transmitter power
supply filter circuit. Locate the
power supply filter circuit as close
as possible to the VCC pin.
Pin 6 Transmitter Power Supply VCCT:
Provide +5 V dc via the
recommended transmitter power
supply filter circuit. Locate the
power supply filter circuit as close
as possible to the VCC pin.
Pin 7 Transmitter Data In Bar TD:
See recommended circuit
schematic, Figure 4.
Pin 8 Transmitter Data In TD:
See recommended circuit
schematic, Figure 4.
Pin 9 Transmitter Signal Ground VEET:
Directly connect this pin to the
transmitter ground plane.
Mounting Studs
The mounting studs are provided
for mechanical attachment 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.
