8T49N2183NLGI

Overview

The 8T49N2183NLGI is a clock generator and frequency synthesizer manufactured by Renesas Electronics Corporation. It belongs to the 8T49N21xx series of timing ICs designed for high-speed serial communication applications. The device integrates a Phase-Locked Loop (PLL) to synthesize precise output clocks from input references. It is classified as an obsolete product in current manufacturer catalogs, indicating it has been superseded by newer generations of timing solutions within the Renesas portfolio.

Feature Summary

• Provides precise clock synthesis for high-speed serial communication systems
• Integrates PLL-based frequency generation capabilities
• Designed for timing stability in data-intensive applications

Applications

• High-speed serial communication interfaces
• Data center infrastructure timing
• Telecommunications equipment synchronization

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin compatibility with existing designs. Check for RoHS compliance documentation if required for specific regulatory environments. Validate that no newer Renesas replacement part offers superior performance for the target application before finalizing procurement decisions.

Selection Notes

Consider this component only for legacy system maintenance or where specific historical design constraints apply. Evaluate newer Renesas timing ICs for improved jitter performance and power efficiency. Ensure input/output frequency requirements match the device's synthesis capabilities. Verify availability through secondary markets if original stock is depleted.

Part Context

This timing IC is part of Renesas' broader portfolio of clock generators and PLLs. It serves as a specialized solution for applications requiring stable clock distribution. The 8T49N21xx series represents a specific generation of timing devices focused on serial link synchronization. Its obsolete status reflects the continuous evolution of Renesas' timing product lines toward lower power and higher precision technologies.

Replacement Considerations

Consult Renesas official cross-reference guides for direct substitutes. Newer 8T49Nxx series variants may offer enhanced specifications. Verify pin-to-pin compatibility before substitution. Review updated datasheets for changes in electrical characteristics and packaging options.
