ADN2871ACPZ-RL7

Overview

The ADN2871ACPZ-RL7 is a single-loop laser diode driver designed for SFP and SFF modules supporting data rates from 50 Mbps to 4.25 Gbps. It operates on a 3.3 V supply within an LFCSP-24 package. The device supports bias currents of 2 mA to 100 mA and modulation currents of 5 mA to 90 mA, with typical rise/fall times of 60 ps. It includes automatic laser shutdown, current monitoring, and interfaces with digital diagnostics.

Feature Summary

• Supports VCSEL, DFB, and FP lasers with average power and extinction ratio control via voltage or resistor setpoints.
• Integrates laser fail alarm and automatic laser shutdown (ALS) for enhanced safety.
• Provides bias and modulation current monitoring capabilities.
• Pin-compatible with the ADN2870 dual-loop driver for design flexibility.

Applications

• Advanced SFP transceiver modules
• SFF optical module designs
• Digital diagnostic interface systems

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm RoHS compliance and moisture sensitivity levels prior to assembly. Ensure storage conditions meet humidity requirements to prevent package degradation during handling and reflow processes.

Selection Notes

Select this driver for single-loop applications requiring high-speed operation up to 4.25 Gbps. It is suitable when pin compatibility with ADN2870 is required for existing designs. Consider its integration with MicroConverter devices for complete transceiver solutions.

Part Context

Part of the ADN287x family of laser diode drivers from Analog Devices. Designed specifically for optical communication modules utilizing SFF-8472 standards. Complements limiting amplifiers like the ADN2890 series for full transceiver functionality.

Replacement Considerations

The ADN2870 is a pin-compatible alternative offering dual-loop control. Verify if dual-loop requirements necessitate switching to the ADN2870 or if single-loop suffices for the specific application.
