ADN2848 Datasheet (Analog Devices) - 3V Dual-Loop 50 Mbps to 1.25 Gbps Laser Diode Driver

ADN2848, 3V Dual-Loop 50 Mbps to 1.25 Gbps Laser Diode Driver

The ADN2848 uses a unique control algorithm to control both the average power and the extinction ratio of the laser diode (LD) after initial factory setup.

External component count and PCB area are low because both power and extinction ratio control are fully integrated.

Programmable alarms are prov
