FUNCTION
Ground
Transmitter Disable, TTL. Laser output is disabled when TX_DISABLE is asserted high or left
unconnected. The laser output is enabled when this pin is asserted low.
3.3V Supply Voltage
Noninverted Data Input
Inverted Data Input
Photodiode-Current Monitor Output. Current out of this pin develops a ground-referenced voltage
across an external resistor that is proportional to the monitor-diode current.
Bias-Current Monitor Output. Current out of this pin develops a ground-referenced voltage across
an external resistor that is proportional to the bias current.
Modulation-Current Monitor Output. Current out of this pin develops a ground-referenced voltage
across an external resistor that is proportional to the modulation current amplitude.
Open-Collector Transmit Fault Indicator (Table 1)
Shutdown Driver Output. Voltage output to control an external transistor for optional shutdown
circuitry.
Bias Voltage Sense. Isolated tap (3k ±15%) on the bias output reduces component count when
a precision bias sense resistor is used.
Laser Bias-Current Output
Inverted Modulation-Current Output (Connect Pins 19 and 20 Together). I MOD flows into this pin
when input data is low.
Noninverted Modulation-Current Output (Connect Pins 21 and 22 Together). I MOD flows into this
pin when input data is high.
Monitor Photodiode Input. Connect this pin to the anode of a monitor photodiode. A capacitor to
ground is required to filter the high-speed AC monitor photocurrent.
Monitor Photodiode Voltage Sense. Isolated tap (3k ±15%) on the MD input reduces
component count when a precision photodiode current-sense resistor is used.
Connect a capacitor (C APC ) between pin 26 (APCFILT1) and pin 27 (APCFILT2) to set the
dominant pole of the APC feedback loop.
(See Pin 26.) The maximum capacitance allowed on this pin is 10pF.
A resistor connected from this pin to ground sets the desired average optical power. The
maximum capacitance allowed on this pin is 10pF.
A resistor connected from this pin to ground sets the desired constant portion of the modulation
current.
Modulation-Current Compensation from Bias. Couples the bias current to the modulation current.
Mirrors I BIAS through an external resistor. Leave open for zero coupling.
Threshold for Temperature Compensation. A resistor at this pin programs the temperature, above
which compensation is added to the modulation current.
Modulation-Current Compensation from Temperature. A resistor at this pin sets the temperature
32
MODTCOMP coefficient of the modulation current when above the threshold temperature. Leave open for zero
temperature compensation.

EP
Exposed Pad. Solder the exposed pad to the circuit board ground for specified thermal and
electrical performance.
