Functional Description

Mounting Studs

The mounting studs are provided for transceiver mechanical attachment to the circuit board.

They are embedded in the housing and are not connected to the transceiver internal circuit.

They should be soldered into plated-through holes on the printed circuit board.

Receiver Signal Ground

Directly connect this pin to receiver signal ground plane.

RD+

Receiver Data Out

Terminate this high-speed, differential, PECL output with standard PECL techniques at the follow-on

device input pin.

3

RD-

Receiver Data Out Bar

Terminate this high-speed, differential, PECL output with standard PECL techniques at the follow-on

device input pin.

SD

Signal Detect

Normal input optical levels to the receiver result in a logic “1” output.Low input optical levels to the

receiver result in a fault indication shown by a logic “0” output.

Signal Detect is a single-ended, PECL output. This output will operate with 270

 termination resistor

This Signal Detect output can be used to drive a PECL input on an upstream circuit, such as, Signal

Detect input and Loss of Signal-bar input.

Transmitter Data In Bar

Terminate this high-speed, differential Transmitter Data input with standard PECL techniques at the

transmitter input pin.

8

TD+

Transmitter Data In

Terminate this high-speed, differential Transmitter Data input with standard PECL techniques at the

transmitter input pin.

Transmitter Signal Ground

Directly connect this pin to the transmitter signal ground plane.
