NT23L50-GRP6

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

• High sensitivity AGC TIA architecture
• Optimized for FTTH and Telecom Fiber transceivers
• Single 3.3V power supply operation

Applications

• FTTH transceivers
• Telecom Fiber transceivers
• BPON systems

Procurement Notes

Verify the specific package type and tape-and-reel configuration against the official datasheet before ordering. Confirm that the 3.3V supply requirement aligns with your system design. Ensure compatibility with standard optical receiver modules intended for BPON or similar legacy telecom standards.

Selection Notes

Select this component when designing receivers for 622Mbps optical links requiring high sensitivity and automatic gain control. It serves as a suitable alternative to higher-speed TIAs like the NT24L50 for cost-sensitive or lower-bandwidth applications such as BPON. Evaluate the 50kΩ gain against your photodiode current requirements.

Part Context

Semtech manufactures a broad portfolio of optical ICs, including TIAs, laser drivers, and CDRs. The NT23L50 belongs to the TIA family, which supports various transmission standards from OC-3 to 10Gbps. These components are critical for converting photocurrent into voltage in optical receivers used in datacom and telecom infrastructure.

Replacement Considerations

The NT24L50 is a related 1.25Gbps AGC TIA within the same product family. Verify if the higher bandwidth of the NT24L50 is necessary or if the 622Mbps speed of the NT23L50 is sufficient for the application.
