8T49N1012-993NLGI

Overview

The 8T49N1012-993NLGI is a clock generator and timing integrated circuit manufactured by Renesas Electronics Corporation. It belongs to the 8T49N series of clock synthesizers designed for high-performance applications requiring precise frequency generation and jitter attenuation. The device features a fractional-feedback phase-locked loop (PLL) architecture, which enables flexible frequency synthesis capabilities. It integrates multiple output drivers to support complex system timing requirements. This component is classified as obsolete and is no longer in active production by the manufacturer.

Feature Summary

• Integrates a fractional-feedback PLL for versatile frequency synthesis
• Provides multiple output channels for complex system timing distribution
• Designed for high-performance clock generation and jitter reduction

Applications

• High-speed data communication systems
• Network infrastructure equipment
• Server and storage subsystems

Procurement Notes

This specific part number is officially classified as obsolete by Renesas Electronics. Availability is limited to existing stock from third-party distributors or surplus markets. Buyers must verify the authenticity, date code, and physical condition of components carefully. Sourcing from authorized channels is critical to avoid counterfeit products. Long-term supply stability cannot be guaranteed, and lifecycle management strategies should account for potential discontinuation impacts on production schedules.

Selection Notes

Engineers designing new hardware should not select this obsolete component. Instead, they should evaluate current Renesas clock generator families that offer equivalent performance specifications. Modern alternatives typically provide improved power efficiency, broader frequency ranges, and better integration features. Consulting the latest Renesas product selection guide ensures compatibility with current manufacturing standards and long-term supply chain security.

Part Context

The 8T49N1012 series represents Renesas' legacy clock synthesizer solutions. These devices were widely used in telecommunications and computing applications prior to newer generations. The -993 suffix typically denotes specific packaging or environmental compliance variations within the standard 8T49N family. Understanding the original design intent helps in identifying suitable modern replacements that match the electrical and functional requirements of the original system.

Replacement Considerations

Official substitutes include the 8T49N1012-994NLGI and 8T49N1012-101NLGI. These variants share the same core functionality but may differ in packaging or minor electrical characteristics. Engineers must verify pinout compatibility and parameter alignment before substitution. Cross-referencing datasheets is essential to ensure seamless integration into existing designs without hardware modifications.
