Functional Description
Laser Bias Monitor (-)
This analog current is monitored by measuring the voltage drop across a 10 ohm
resistor placed between high impedance resistors connected to pins 5 and 6 internal to
the transceiver.

Signal Ground
Directly connect this pin to the signal ground plane.
Transmitter Data In
Requires an ac coupled input. The input stage is internally biased and 50 ohm
terminated.
Transmitter Data In Bar
Requires an ac coupled input. The input stage is internally biased and 50 ohm
terminated.
Transmitter Power Supply
Provide +5 V dc via a transmitter power supply filter circuit. Locate the power supply
filter circuit as close as possible to the V
CCT
pin.
Receiver Power Supply
Provide +5 V dc via a receiver power supply filter circuit. Locate the power supply
filter circuit as close as possible to the V
CCR
pin.
Signal Detect
Normal input optical data levels above the receiver sensitivity result in a logic
1
output. Loss of optical power to the receiver results in a fault indication shown by a
logic
0
output.

Signal Detect is a single-ended, internally terminated TTL output.
This Signal Detect output can be used to drive a TTL input on an upstream circuit,
such as, Signal Detect input or Loss of Signal-bar input.
