Laser Drivers Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or discontinuation. Confirm the exact suffix ETG+ matches the required package and lead-free specifications. Check official Analog Devices documentation for current lifecycle status and recommended replacement parts if necessary.

Laser Drivers Selection Notes

Select this component when designing SFP+ compliant optical engines requiring drivers up to 11.3 Gbps. Ensure the system power supply remains within the 2.85 V to 3.63 V range. Verify that the TQFN-EP-24 footprint aligns with the PCB layout constraints and thermal management requirements of the target application.

Laser Drivers Part Context

This device belongs to the MAX3946 family of laser drivers manufactured by Analog Devices / Maxim Integrated. It is specifically engineered for short-reach optical interconnects. The ETG+ designation indicates the specific tape-and-reel or tube packaging variant with RoHS compliance, distinguishing it from other pinout or speed variants in the broader product line.

Laser Drivers Replacement Considerations

Public records indicate the MAX3946ETG+ has been discontinued or stopped providing by distributors. Designers should consult official manufacturer resources for qualified alternative components or updated product lines that maintain compatibility with existing SFP+ designs.
