NAME
FUNCTION
1
TC
Temperature Compensation Set. The resistor at TC programs the temperature-increasing component
of the laser-modulation current.
Fault Indicator. See Table 1.
Ground
Transmit Disable. Laser output is disabled when TX_DISABLE is high or left unconnected. The laser
output is enabled when this pin is asserted low.

PORDLY
Power-On Reset Delay. A capacitor connected between PORDLY and GND can be used to extend the
delay for the power-on reset circuit. See the
Design Procedure
section.
Supply Voltage
Noninverting Data Input
Inverting Data Input
Attaches to the emitter of the bias driving transistor through a 10
resistor. See the
Design Procedure
section.
This pin attaches to the emitter of the bias driving transistor. See the
Design Procedure
section.
A capacitor connected from this pin to ground sets the dominant pole of the APC loop. See the
Design
Procedure
section.
Monitor Diode Connection. MD is used for automatic power control.
Shutdown Driver Output. Provides a redundant laser shutdown.
Laser Bias Current Output
Positive Modulation-Current Output. Current flows from this pin when input data is high.
Negative Modulation-Current Output. Current flows to this pin when input data is high.
A resistor connected from this pin to ground sets the desired modulation current.
Ground. This must be soldered to the circuit board ground for proper thermal and electrical
performance. See the
Layout Considerations
section.
