Ground
Sink Current Source. Proportional to the laser bias current.
Sink Current Source. Proportional to the laser modulation current.
TTL/CMOS Enable Input. High for normal operation, low to disable laser bias and
modulation currents. Internally pulled high.
TTL Output. Indicates APC failure when low. Internally pulled high through a 6k
No Connection. Leave unconnected.
Laser Bias Current Output. Isolate from laser with a ferrite bead.
Positive Modulation Current Output. I MOD flows into this pad when the input signal is
high. Connect this pad to AC-coupling network.
Negative Modulation Current Output. I MOD flows into this pad when the input signal is
low. Connect this pad to V CC through a 6.3 resistor.
Monitor Photodiode Connection. Connect this pad to the monitor photodiode anode.
A capacitor to ground is required to filter high-speed AC monitor photocurrent.
APC Compensation Capacitor. A 0.1 μF capacitor connected from this pad to ground
controls the dominant pole of the APC feedback loop.
APC Set Resistor. A resistor connected from this pad to ground sets the desired average

optical power. The resulting current is equal to the desired DC monitor diode current.
Connect a 100k
resistor from this pad to ground if APC is not used.
Modulation Set Resistor. A resistor from this pad to ground sets the laser modulation
current.
Maximum Bias Set Resistor. A resistor from this pad to ground sets the maximum laser

bias current. The APC function can subtract from this maximum value but cannot add to
it. This resistor controls the bias-current level when the APC loop is not used.
