MAXIM MAX3273† +3.3V 2.5Gbps Low-Power Laser Driver Manual
Update: 29 September, 2023
The MAX3273 is a compact, low-power laser driver for applications up to 2.7Gbps. The device uses a single +3.3V supply and typically consumes 30mA. The bias and modulation current levels are programmed by external resistors. An automatic power-control (APC) loop is incorporated to maintain a constant average optical power over temperature and lifetime. The laser driver is fabricated using Maxim’s in-house, second-generation SiGe process. The MAX3273 accepts differential CML-compatible clock and data input signals. Inputs are self-biased to allow AC-coupling. An input data-retiming latch can be enabled to reject input jitter if a clock signal is available. The driver can provide bias current up to 100mA and modulation current up to 60mAP-P with typical (20% to 80%) edge speeds of 59ps. A failure-monitor output is provided to indicate when the APC loop is unable to maintain average optical power. The MAX3273 is available in a 4mm✕4mm, 24-pin QFN package, as well as in die form.
