NT23L50-WP

Overview

The NT23L50 is a high sensitivity Transimpedance Amplifier (TIA) designed for optical fiber transceiver applications. It operates at a data rate of 622Mbps and features an Automatic Gain Control (AGC) circuit to maintain signal integrity across varying input levels. The device provides a gain of 50kΩ with a bandwidth of 0.32GHz, powered by a single 3.3V supply. With a noise specification of 60nA, it is optimized for FTTH and Telecom Fiber environments.

Feature Summary

• Integrates Automatic Gain Control (AGC) for stable operation in variable signal conditions
• Optimized for high sensitivity in FTTH and telecom fiber transceiver modules
• Designed for low power consumption within a compact package

Applications

• FTTH transceivers
• Telecom Fiber transceivers
• OC-12 systems
• BPON applications

Procurement Notes

Verify the specific ordering suffix against Semtech's current Optical & IC Selector Guide or datasheet to ensure compatibility with your design requirements. Confirm that the component meets all necessary environmental and electrical specifications for your target application before finalizing procurement.

Selection Notes

Select this TIA when designing optical receivers requiring 622Mbps performance with AGC functionality. It serves as a suitable alternative to higher-speed TIAs like the NT24L50 for legacy or lower-rate BPON and OC-12 implementations where cost and power efficiency are prioritized over extended bandwidth.

Part Context

Semtech offers a comprehensive portfolio of optical components including TIAs, laser drivers, and ROSAs. The NT23L50 belongs to the TIA category, which provides wideband, low-noise pre-amplification for PIN photodiodes or APDs. These components support various transmission standards from OC-3 to 100Gbps.

Replacement Considerations

The NT24L50 is a documented 1.25Gbps AGC TIA that may serve as a functional replacement if the application supports the higher data rate. Verify pinout compatibility and interface requirements before substituting.
