Function
Peaking adjustment input. A resistor (2kΩ to 20kΩ) between this pin and ground
sets the amount of peaking current on OUT- to improve the fall time of the laser
output. The peaking current is approximately (4 * (1.3V / resistance to ground)).
Connect to V_CC3 to disable peaking control.

Modulation current temperature compensation slope adjustment. Connect a
resistor to ground to set the temperature coefficient. Leave open to minimize the
temperature compensation coefficient.
Ground. Must be connected to ground for proper operation. This is the only
package ground connection.
