M02069 Data Sheet

CAPC

Automatic power control loop dominant pole capacitor. (Connect a capacitor

between this pin and VCC3.)

A nominal capacitance of 2.2nF will give a bias current enable time of less than 1

ms.

VCC3

3.3V applications - Power supply input. Connect to VCC.

5V applications - Do not connect to 5V. Internally generated 3.3V power supply

output. Do not attach to non-M02069 circuitry.

PEAKADJ

Peaking adjustment input. A resistor (2k

Ω 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 (5 * (1.3V / 2 k

Ω + resistance to

ground)).

Connect to VCC3 to disable peaking control.
