NT24L50-WP

Overview

The NT24L50 is a 1.25Gbps high sensitivity Transimpedance Amplifier (TIA) featuring automatic gain control, designed for FTTH and Datacom Fiber transceiver applications. It operates at a data rate of 1.25 Gbps with a gain of 25 kΩ and a bandwidth of 0.75 GHz. The device requires a single 3.3V supply voltage and exhibits an input noise current density of 92nA.

Feature Summary

• Integrates automatic gain control to maintain signal integrity across varying optical input levels
• Delivers high sensitivity performance suitable for long-reach fiber optic links
• Optimized for compact form factor integration in FTTH and datacom modules

Applications

• FTTH transceivers
• Datacom fiber transceivers
• GbE optical modules
• EPON systems

Procurement Notes

Verify the specific package type and tape-and-reel specifications against the official datasheet before ordering. Confirm that the 3.3V supply requirement aligns with your system design constraints. Ensure compatibility with standard PIN photodiodes used in your target application.

Selection Notes

Select this component when designing receivers requiring 1.25Gbps operation with moderate gain requirements. Compare its 25kΩ gain against higher-gain alternatives like the NT24L55 if extended reach or lower optical power inputs are critical. Evaluate the 92nA noise specification against system sensitivity budgets.

Part Context

Semtech provides a comprehensive portfolio of optical ICs including TIAs, laser drivers, and CDRs for Ethernet, PON, and Fibre Channel standards. The NT24L50 belongs to the TIA family, supporting Gigabit Ethernet and EPON applications alongside other models like the NT23L50 and NT24L55.

Replacement Considerations

The NT24L55 offers higher sensitivity with 46kΩ gain but may require different biasing considerations. The NT23L50 supports 622Mbps rates with 50kΩ gain. Verify pinout and electrical characteristics before substituting.
