3 Gbps Laser Diode Driver ADN2872
GENERAL DESCRIPTION
Like the ADN2870, the ADN28721 laser diode driver is designed for advanced SFP and SFF modules, using SFF-8472 digital diagnostics.
The device features dual-loop control of the average power and extinction ratio, which automatically compensates for variations in laser characteristics over temperature and aging.
The laser needs only be calibrated at 25°C, eliminating the need for expensive and time consuming temperature calibration.
The ADN2872 supports single-rate operation from 50 Mbps to 3.
3 Gbps, or multirate operation from 155 Mbps to 3.
3 Gbps.
