3.1

Overview

The M02066 laser driver consists of a high-speed modulation driver and a laser bias generator with mean power

control (MPC). It is optimized for high speed, low power operation at 3.3V supply. To minimize the pattern-

dependent jitter of the input signal, the device accepts an input clock signal for data retiming. This feature can be

enabled using the external CEN pin.
