• Manufacturer: HP [Agilent(Hewlett-Packard)]

Connection Diagram
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 receiver power
supply filter circuit. Locate the
power supply filter circuit as
close as possible to the V
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.

Mounting Studs/Solder Posts
The two 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.
Package Grounding Tabs
Connect four package grounding
tabs to signal ground.
