MAX3735AEGG

Laser Drivers Overview

The MAX3735AEGG is a laser driver designed for SFP/SFF applications, supporting data rates from 155 Mb/s to 2.7 Gb/s. It operates at a supply voltage of 3.3 V with a typical power-supply current of 27 mA and maximum power dissipation of 1.354 W. The device features programmable modulation currents ranging from 10 mA to 60 mA (DC-coupled) or up to 85 mA (AC-coupled), and bias currents from 1 mA to 100 mA. Edge transition times are less than 51 ps. It includes automatic average power control and complies with SFP MSA timing and SFF-8472 transmit diagnostic requirements.

Laser Drivers Procurement Notes

Verify the specific suffix 'EGG' against official Analog Devices documentation to confirm package type and temperature range. Confirm end-of-life status as sources indicate discontinuation. Ensure compatibility with existing PCB footprints and thermal management designs before procurement.

Laser Drivers Selection Notes

Select this component for low-power SFP designs requiring precise laser control. Verify that the required modulation and bias current ranges match the target laser diode characteristics. Ensure the design supports the necessary external components for APC loop stability and digital potentiometer interfacing for current settings.
