Functional Description

The mounting studs are provided for transceiver mechanical attachment to the circuit boards, they are

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

should be soldered into plated-through holes on the printed circuit board and not connected to signal

ground.

Receiver Signal GroundDirectly connect this pin to receiver signal ground plane. Receiver VEER and trans-

mitter VEET can connect to a common circuit board ground plane.

Receiver Data Out

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

device input pin.

Receiver Data Out Bar

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

device input pin.

Signal Detect

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

levels to the receiver result in a fault condition indication shown by a logic “0” output (VOL).If Signal Detect

output is not used, leave it open-circuited.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.

Receiver Power Supply

Provide +5 V dc via the recommended receiver VCCR power supply filter circuit.Locate the power supply

filter circuit as close as possible to the VCCR pin.

Transmitter Power Supply

Provide +5 V dc via the recommended transmitter VCCT power supply filter circuit.Locate the power supply

filter circuit as close as possible to the VCCT pin.

Transmitter Data In Bar

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

transmitter input pin.

Transmitter Data InTerminate this high-speed, differential, Transmitter Data input with standard PECL

techniques at the transmitter input pin.

Transmitter Signal GroundDirectly connect this pin to the transmitter signal ground plane. Transmitter

VEET and receiver VEER can connect to a common circuit board ground plane.
