NT25L51-PR

Overview

The NT25L51-PR is a high-sensitivity transimpedance amplifier (TIA) manufactured by Semtech Corporation. It utilizes CMOS technology and incorporates automatic gain control (AGC) to achieve a dynamic operating range exceeding 27dB. Designed for optical communication systems, this component supports data rates up to 2.5 Gb/s with a 3dB bandwidth of 1.7 GHz. It operates on a single 3.3V supply and features an input noise current of 230nA. The device is supplied as a bare die intended for surface mount integration.

Feature Summary

• Integrates automatic gain control to maintain signal integrity across varying optical power levels
• Utilizes CMOS fabrication for optimized performance in fiber optic receiver designs
• Provides wideband amplification suitable for high-speed serial data transmission

Applications

• GPON networks utilizing Avalanche Photodiodes (APD)
• OC-48 SONET transmission systems
• High-performance optical transceiver modules

Procurement Notes

Verify the specific ordering suffix against official Semtech documentation to confirm package configuration and testing parameters. Ensure compatibility with existing photodiode interfaces and power supply requirements before finalizing procurement. Confirm availability through authorized distribution channels.

Selection Notes

Select this component for applications requiring high sensitivity and wide dynamic range in 2.5Gbps optical receivers. The integrated AGC simplifies design complexity compared to fixed-gain alternatives. Evaluate thermal management requirements for the bare die format during system integration.
