The Analog Devices MAX3949ETE+ is a versatile laser diode driver designed for high-speed communication systems, including Ethernet, Fibre Channel, and SONET. Operating at 3.3V, this device supports data rates up to 11.3Gbps, making it suitable for demanding applications.
Key electrical specifications include a programmable modulation current of up to 85mA into a 5-ohm load and a programmable bias current of up to 105mA. The device features on-chip termination for differential AC-coupled signals and integrated back termination resistors. An input equalization block can be activated to compensate for host connector losses, and output deemphasis can be adjusted.
The MAX3949ETE+ is housed in a compact 16-pin TQFN (3x3mm) package, suitable for surface mounting. It is specified for an extended operating temperature range of -40°C to +95°C, ensuring reliability in various environmental conditions. The device also includes integrated eye safety features and a fault mask capability.
This laser driver is optimized for driving differential transmit optical subassemblies (TOSAs) and is compatible with SFF-8431 SFP+ MSA and SFF-8472 Digital Diagnostic standards. Its low power consumption and small package size contribute to board space savings.
