NT23L50-GRP8

Overview

The NT23L50-GRP8 is a high-sensitivity Transimpedance Amplifier (TIA) designed for optical fiber transceiver applications. It operates at a data rate of 622 Mbps and features Automatic Gain Control (AGC). The device provides a gain of 50 kΩ with a bandwidth of 0.32 GHz. It requires a single 3.3V supply voltage and exhibits a noise performance of 60nA. This component is specifically engineered for FTTH and Telecom Fiber environments, supporting standards such as OC-12 and BPON.

Feature Summary

• Integrates Automatic Gain Control to maintain signal integrity across varying input levels
• Optimized for high sensitivity in fiber optic receiver circuits
• Designed for low power consumption within standard telecom voltage rails

Applications

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

Procurement Notes

Verify the specific ordering suffix GRP8 against official Semtech documentation to confirm package type and environmental compliance status. Ensure compatibility with existing photodiode interfaces and system voltage requirements before integration. Consult authorized distributors for current availability and lead times.

Selection Notes

Select this TIA for designs requiring 622 Mbps operation with AGC functionality. Compare gain and noise specifications against alternative TIAs like the NT24L50 if higher data rates are needed. Consider the 50 kΩ gain and 0.32 GHz bandwidth limits when designing the front-end circuit for OC-12 or BPON applications.

Part Context

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

Replacement Considerations

The NT24L50 is a similar AGC TIA operating at 1.25 Gbps with different gain and noise characteristics. Verify pinout and electrical parameter compatibility before substitution.
