ADN2871 Datasheet (Analog Devices) - Single-Loop Laser Diode Driver

ADN2871, Single-Loop Laser Diode Driver

The ADN2871 laser diode driver is designed for advanced SFP and SFF modules, using SFF-8472 digital diagnostics.

The ADN2871 supports operation from 50 Mbps to 4.25 Gbps.

Average power and extinction ratio can be set with a voltage provided by a microcontroller DAC or by a trimmable resistor or digi
