Transmitter Data In
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 holes
on the printed circuit board.
Receiver Signal Ground
Directly connect this pin to receiver signal ground plane. (For HFBR-53D5, V
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.
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.
Signal Detect
Normal optical input levels to the receiver result in a logic “1” output, V
Low input optical levels to the receiver result in a fault condition indicated by
a logic “0” output V
Signal Detect is a single-ended PECL output. SD can be terminated with standard PECL
techniques via 50

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 Vdc via the recommended receiver power supply filter circuit.
Locate the power supply filter circuit as close as possible to the V
Transmitter Power Supply
