Modulation-Current Output. See the Typical

Application Circuits.

Modulation-Current Set. The resistor at

MODSET programs the temperature-stable

component of the laser modulation current.

Temperature-Compensation Set. The resistor

at TC programs the temperature-increasing

component of the laser modulation current.

Ground. This must be soldered to the circuit

board ground for proper thermal

performance. See Layout Considerations.
