Pin Description

NAME

FUNCTION

1, 4, 9,

+3.3V Supply Voltage. All pins must be connected to V

CC.

IN+

IN-

Noninverted Data Input

Inverted Data Input

A current DAC, a voltage DAC, or a resistor, connected from this pin to ground, sets the desired bias

current for the laser (see the Programming the Laser Bias Current section).

BIASSET

MODSET

BC_MON

A current DAC, a voltage DAC, or a resistor, connected from this pin to ground, sets the desired bias

current for the laser (see the Programming the Laser Modulation Current section).

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.

BIAS

OUT+

OUT-

GND

Laser Bias Current Output

Noninverted Modulation Current Output. I

flows into this pin when input data is high.

MOD

Inverted Modulation Current Output. I

Ground

flows into this pin when input data is low.

MOD

13, 14

Transmitter Disable, TTL. Laser output is disabled when DIS is asserted high or left

unconnected. The laser output is enabled when this pin is asserted low.

DIS

Exposed Pad. Must be soldered to the circuit board ground for proper thermal and electrical

performance (see the Exposed-Pad Package section).
