The MAX3643ETG+ from Analog Devices / Maxim Integrated is a high-speed burst-mode laser driver specifically designed for PON burst-mode ONT applications. It provides both bias and modulation current drive for lasers, allowing for precise control.
Key electrical specifications include a modulation current range of 10mA to 85mA and a bias current range of 1mA to 70mA, both settable via external inputs. The device features a fast 2ns turn-on/off time and a 45ps output transition time, enabling rapid switching from a dark to an on-condition. It supports data rates up to 2.5Gbps and operates from a 3V to 3.6V supply voltage.
The MAX3643ETG+ is housed in a compact 4mm x 4mm, 24-pin thin QFN package. It is designed for surface mount applications and operates reliably within an ambient temperature range of -40°C to +85°C, making it suitable for demanding environments.
This laser driver is ideal for use in A/B/G/XGPON ONT modules up to 2.5Gbps and 1.25Gbps IEEE EPON ONT modules. It includes features like a monitor diode sample-and-hold circuit and LVPECL high-speed inputs.
