Received Recovered Clock Out
See pins 1 and 2 for optional, local generated clock output.
Functional Description
The falling edge occurs coincident with the edges of the Received Data output. The
rising edge occurs in the middle of the Received Data baud period.
Terminate this high-speed, differential clock output with standard PECL techniques
at the clock input point of the follow-on device.
If this clock output is not used, leave it open-circuited with no printed circuit board
trace attached to this output pin.
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.
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.

Transmitter Signal Ground
Directly connect this pin to the transmitter signal ground plane.
Transmitter Data In
Terminate this high-speed, differential Transmitter Data input with with standard
PECL techniques at the transmitter input pin.
Transmitter Data In Bar
Terminate this high-speed, differential Transmitter Data input with standard PECL
techniques at the transmitter input pin.
Transmitter 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 Vcct pin.
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.
