ADN2525ACPZ-R2

Overview

The ADN2525ACPZ-R2 is a differential laser diode driver from Analog Devices, designed for high-speed optical communication applications. It supports data rates up to 10.7 Gbps and features on-chip active back-termination to ensure signal integrity. The device operates with a single 3.3 V supply and draws a typical operating current of 46 mA. Packaged in a compact LFCSP-16 format, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates an output stage with differential configuration and on-chip active back-termination to maintain high-quality eye diagrams at lower power consumption compared to traditional approaches.

Applications

• High-speed optical transceivers
• Fiber optic communication systems
• Data center interconnects

Procurement Notes

Verify the specific suffix R2 indicates reel packaging when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure compatibility with existing PCB footprints and thermal management requirements for the LFCSP-16 package before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a single-supply, low-power solution for driving laser diodes at 10.7 Gbps. The integrated active back-termination simplifies board layout by reducing external component count. Consider the LFCSP-16 package size for space-constrained applications where thermal dissipation must be managed effectively within the specified operating temperature range.

Part Context

This part belongs to the ADN252x series of laser drivers from Analog Devices, which are optimized for short-reach optical links. The series includes variants like the ADN2526 for slightly higher speeds. These drivers are commonly used in enterprise networking and storage area networks where power efficiency and signal quality are critical performance metrics.

Replacement Considerations

The ADN2526ACPZ-R2 serves as a functional substitute offering support for 11.3 Gbps data rates. Designers should verify pin-to-pin compatibility and adjust biasing settings if upgrading to the higher-speed variant.
