APCSET
APC Set Resistor. A resistor connected from this pad to ground sets the desired average opti-
cal 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.

BIASMAX
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.

N.C.
No Connection. Leave unconnected.

FAIL
TTL Output. Indicates APC failure when low. Internally pulled high through a 6k
resistor.
9
ENABLE
TTL/CMOS Enable Input. High for normal operation, low to disable laser bias and modulation
currents. Internally pulled high.
BIAS
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.

OUT-
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 capaci-
tor to ground is required to filter high-speed AC monitor photocurrent.

CAPC
APC Compensation Capacitor. A 0.1μF capacitor connected from this pad to ground controls
the dominant pole of the APC feedback loop.
