Functional Description

Mounting Pins The mounting pins are provided for transceiver mechanical attachment to the circuit board.

They are embedded in the nonconductive plastic housing and are not connected to the

transceiver internal circuit, nor is there a guaranteed connection to the metallized housing

in the EM and FM versions. They should be soldered into plated-through hole on the

printed circuit board.

1 VEER Receiver Signal Ground

Directly connect this pin to receiver signal ground plane. (For HFBR-53D3, VEER = VEET)

2 RD+ Receiver Data Out

RD+ is an open-emitter output circuit. Terminate this high-speed differential PECL output

with standard PECL techniques at the follow-on device input pin.

3 RD– Receiver Data Out Bar

RD– is an open-emitter output circuit. Terminate this high-speed differential PECL output

with standard PECL techniques at the follow-on device input pin.

SD Signal Detect

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

Low input optical levels to the receiver result in a fault condition indicated by a logic “0”

output VOL, deasserted.

Signal Detect is a single-ended PECL output. SD can be terminated with standard PECL

W W techniques via 50 to VCCR - 2 V. Alternatively, SD can be loaded with a 270 resistor to

VEER to conserve electrical power with small compromise to signal quality. 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.

VCCR Receiver Power Supply

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

Locate the power supply filter circuit as close as possible to the VCCR pin.

6

VCCT Transmitter Power Supply

Provide +5 Vdc via the recommended transmitter power supply filter circuit.

Locate the power supply filter circuit as close as possible to the VCCT pin.

7 TD– Transmitter Data In-Bar

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

transmitter input pin.

8 TD+ Transmitter Data In

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

transmitter input pin.
