NT25L51-WP

Overview

The NT25L51-WP is a high-sensitivity transimpedance amplifier (TIA) manufactured by Semtech using CMOS technology. It features automatic gain control (AGC) to achieve a dynamic operating range exceeding 27dB, making it suitable for GPON applications with APD and OC-48 SONET systems. The device operates at a data rate of 2.5 Gbps with a 3dB bandwidth of 1.7 GHz. It requires a 3.3V supply voltage and has an input noise current of 230nA. The component is available as a bare die in SMD/SMT installation style.

Feature Summary

• Integrates automatic gain control (AGC) functionality within a CMOS process.
• Provides wideband, low-noise pre-amplification for optical receiver signals.
• Designed for high sensitivity in fiber optic communication environments.

Applications

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

Procurement Notes

Verify the specific ordering suffix and package configuration against the manufacturer's latest documentation before finalizing procurement. Confirm that the bare die format aligns with your assembly capabilities and board design requirements. Ensure compatibility with your system's power supply specifications and thermal management strategies. Cross-reference the part number with official distributor catalogs to validate current availability and lead times.

Selection Notes

Select this component when designing optical receivers for GPON or OC-48 applications requiring high sensitivity and broad dynamic range. The integrated AGC feature simplifies design by accommodating varying signal strengths without external adjustment circuits. Consider the CMOS manufacturing process for cost-effective integration into modern optical transceiver modules. Evaluate the 3.3V supply requirement against your system's power budget constraints.
