The MAX3656ETG+ is a versatile burst-mode laser driver from Analog Devices / Maxim Integrated, capable of operating at data rates from 155Mbps up to 2.5Gbps. This device is designed to provide bias and modulation current for laser diodes, enabling rapid switching between off and on states in less than 2ns. It features DC-coupled operation and accepts PECL or CML data inputs.
Key electrical specifications include a programmable bias current range of 1mA to 70mA and a programmable modulation current range of 10mA to 85mA. The device operates with a single supply voltage as low as +3.0V and typically consumes 40mA of supply current, excluding bias and modulation currents. An integrated digital automatic power-control (APC) loop maintains average optical power over temperature and lifetime, with a fail monitor to indicate when power levels cannot be maintained.
The MAX3656ETG+ is suitable for applications such as Fiber-to-the-Home (FTTH) and Fiber-to-the-Business (FTTB) broadband access systems, and Passive Optical Network (PON) transmitters, including APON, EPON, and GPON upstream transmitters.
Packaged in a compact 24-pin, 4mm x 4mm thin QFN, the MAX3656ETG+ is designed for surface mounting. Its small footprint and efficient operation make it ideal for space-constrained designs in optical networking equipment.
