SIGNAL DETECT
The mounting studs are provided for transceiver mechanical attachment to the circuit
board, they are embedded in the nonconductive plastic housing and are not tied 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.
Receiver Data Out
See recommended circuit schematic.
Receiver Data Out Bar
See recommended circuit schematic.
Signal Detect
Normal optical input levels to the receiver result in a logic “1” output.
Low optical input levels to the receiver result in a fault condition indication shown by
a logic “0” output.
Signal Detect is a single-ended, low-power, PECL output. Since SD is a low-power
PECL output, complete the interconnection of SD output with other PECL inputs using
a 10 k
this SD output with standard PECL, 50
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 transmitter power supply filter circuit.
Locate the power supply filter circuit as close as possible to the V
