MAX3669EHJ+

Laser Drivers Overview

The MAX3669EHJ+ is a complete +3.3V laser driver with automatic power control (APC) circuitry designed for SDH/SONET applications up to 622Mbps. It accepts differential PECL inputs and provides bias and modulation currents. The device operates on a single +3.3V or +5.0V supply, drawing 40mA at +3.3V. Key electrical parameters include programmable bias current from 1mA to 80mA and modulation current from 5mA to 75mA. It features 200ps rise/fall time and includes monitors for both bias and modulation currents.

Laser Drivers Procurement Notes

Verify the specific suffix EHJ+ against the manufacturer's official datasheet to confirm package type and RoHS compliance status. Confirm availability as this component may be subject to limited supply or obsolescence notices. Ensure the ordering information matches the exact voltage and temperature grade requirements for your design.

Laser Drivers Selection Notes

Select this component for designs requiring integrated APC and current monitoring in a single supply architecture. Verify that the input interface supports differential PECL signals. Check that the required modulation and bias current ranges fall within the 5mA-75mA and 1mA-80mA limits respectively. Ensure the operating temperature range of -40°C to +85°C meets environmental specifications.
