NT24L55-DTF8S

Overview

The NT24L55-DTF8S is a high-performance CMOS transimpedance amplifier (TIA) designed for optical fiber communication systems. It operates at data rates up to 1.25Gbps and provides an ultra-high sensitivity of 74nA input noise current with a gain of 46kΩ. The device features automatic gain control (AGC) and supports a dynamic operating range of 35dB, making it suitable for FTTH applications such as GEPON transceivers and long-haul telecom or datacom links.

Feature Summary

• Ultra-high sensitivity design optimized for low-light reception in fiber optic networks
• Integrated automatic gain control mechanism to maintain signal integrity across varying input levels
• High dynamic operating range capability for robust performance in diverse transmission environments

Applications

• FTTH GEPON transceiver modules
• Long haul telecom optical receivers
• Datacom fiber optic interconnects

Procurement Notes

Verify the specific suffix DTF8S against official Semtech documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts by checking pin assignments and thermal requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement plans.

Selection Notes

Select this component when designing optical receivers requiring high sensitivity at 1.25Gbps speeds. The integrated AGC simplifies circuit design by handling wide dynamic ranges without external adjustment components. Consider its suitability for cost-sensitive FTTH deployments where power consumption and board space are critical constraints.

Part Context

This TIA belongs to Semtech's portfolio of optical receiver solutions targeting broadband access networks. It complements other devices like the NT24L50 and NT23L50 within the same series, offering enhanced sensitivity metrics specifically tailored for GPON and EPON standards prevalent in modern fiber-to-the-home infrastructure.

Replacement Considerations

Consult official Semtech substitution guides for verified alternatives. Generic replacements may not match the specific noise figure or dynamic range characteristics required for compliant PON module designs.
