MAX3735AETG+

Laser Drivers Overview

The MAX3735AETG+ is a low-power laser driver designed for Small Form-factor Pluggable (SFP) transceivers. It supports data rates from 155 Mb/s to 2.7 Gb/s and operates on a single 3.3 V supply with a typical quiescent current of 27 mA. The device features programmable modulation currents ranging from 10 mA to 60 mA for DC-coupled outputs and 10 mA to 85 mA for AC-coupled configurations. Bias current is adjustable from 1 mA to 100 mA, with edge transition times under 51 ps. Packaged in a 24-pin TQFN (4 mm x 4 mm), it complies with SFP and SFF-8472 MSA standards.

Laser Drivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Check for lead time constraints due to potential limited availability. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering. Validate pinout compatibility with target PCB footprint.

Laser Drivers Selection Notes

Select this driver for designs requiring strict adherence to SFP MSA specifications. Consider the specific coupling method (DC vs AC) when determining required modulation current range. Evaluate thermal dissipation capabilities within the 24-TQFN package for the intended enclosure. Verify that the programmable current ranges align with the selected laser diode characteristics.
