M02042G-4D01-T

Overview

The M02042G-4D01-T is a CMOS IC designed for high-speed LED drive in low-cost optical fiber transmission systems. It supports data rates exceeding 300 Mbps and operates on a single +5 V to +3.3 V supply. The device features programmable output current ranging from 5 mA to 120 mA, set via an external resistor. It includes RC-programmable pre-emphasis for rise/fall times under 500 ps and resistor-programmable temperature compensation over a 500–10,000 ppm/°C range. The component accepts differential PECL inputs with optional pulse width adjustment and provides a VREF output for single-ended compatibility.
