3.0 Functional Description

3.1

Overview

The M02094 is a highly integrated laser driver intended for applications to 2.0 Gbps.

Many features are user-adjustable, including common anode or common cathode laser mode, the APC (automatic

power control) loop bias control (via a monitor photodiode), modulation current, temperature compensation control

of modulation current, and peaking adjustment. The part may be operated from a 3.3V or 5V supply.

For E-PON and other burst-mode applications, the part supports fast and accurate turn-on and turn-off of the laser

bias and modulation currents.

Safety circuitry is also included to provide a latched shut-down of laser bias and modulation current if a fault condi-

tion occurs. An internal VCC switch provides redundant shutdown when operating the device in common anode

configuration. An internal ground switch provides redundant shutdown when operating the device in common cath-

ode configuration.

Modulation, bias, and transmit power monitor current mirrors are provided for DDMI applications and allow moni-

toring without disturbing the analog signal path.
