The mounting pins are provided for transceiver mechanical attachment to the circuit board. They
Functional Description
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-53A5VM, V
Receiver Data Out
AC coupled – PECL compatible.
Receiver Data Out Bar
AC coupled – PECL compatible.
Signal Detect
Signal Detect is a single-ended TTL output. If Signal Detect output is not used, leave it
open-circuited.
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

Receiver Power Supply
Provide +3.3 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
Provide +3.3 Vdc via the recommended transmitter power supply filter circuit.
Locate the power supply filter circuit as close as possible to the V
