• Integrated non-volatile EEPROM for persistent configuration storage
• Programmable FemtoClock NG technology for precise frequency synthesis
• Designed for low-jitter performance in high-speed data transmission

Applications

• Telecommunications base stations and backhaul equipment
• High-speed data communication interfaces
• Network infrastructure requiring precise clock distribution
• Test and measurement instrumentation

Procurement Notes

This component is officially listed as End-of-Life (EOL) by Renesas Electronics. Product discontinuation notifications have been issued, indicating that standard production has ceased. Procurement should focus on verifying remaining stock availability through authorized distributors or exploring qualified replacement parts from the same manufacturer family. Direct new manufacturing orders are not available.

Selection Notes

Designers must account for the EOL status when selecting this part for new products. Verify that the specific output voltage levels (LVPECL/LVDS) match the target system requirements. Since the device is discontinued, alternative solutions within the FemtoClock series should be evaluated for long-term supply chain stability and pin-to-pin compatibility with existing designs.

Part Context

The 8T49N008A-062NLGI is part of Renesas's FemtoClock portfolio, which succeeded earlier IDT timing products following the company's acquisition. This specific model represents a multi-output synthesizer variant optimized for applications needing multiple synchronized clock signals with minimal added jitter. It serves as a critical timing element in systems where signal integrity is paramount.

Replacement Considerations

Consult Renesas official documentation for direct replacements within the 8T49N008A series or newer FemtoClock generations. Verify electrical specifications and pinout compatibility before substitution. No specific substitute part numbers are confirmed in the provided source material.
