8T49N286-000NLGI8

Application Specific Clock/Timing Overview

The 8T49N286-000NLGI8 is a Universal Frequency Translator (UFT) from Renesas Electronics, part of the FemtoClock NG series. It functions as a clock synthesizer and jitter cleaner designed for high-performance timing applications. The device supports multiple input formats including LVPECL, LVDS, HCSL, and crystal inputs, with differential outputs available in LVPECL, LVDS, or LVCMOS configurations. It operates within a supply voltage range of 2.375V to 3.465V and is rated for an industrial temperature range of -40°C to +85°C. The component utilizes a 72-VFQFN exposed pad package.

Application Specific Clock/Timing Feature Summary

• Universal Frequency Translator architecture supporting integer and fractional-N PLL modes
• Supports up to 8 differential output clocks with configurable output types
• Integrated I2C interface for programmable configuration via external EEPROM
• Low phase noise performance suitable for telecommunications and datacom applications

Application Specific Clock/Timing Applications

• Synchronous Ethernet (SyncE) network equipment
• SONET/SDH transmission systems
• Base station infrastructure
• High-speed data communication interfaces

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix '000' against the official Renesas ordering guide, as this code typically denotes a factory-programmed frequency plan rather than a blank device. Confirm package availability and lead times directly with authorized distributors, as stock levels fluctuate. Ensure compatibility with existing I2C addressing and EEPROM programming tools used in the design.

Application Specific Clock/Timing Selection Notes

Select this component when a single clock source must generate multiple frequencies with low jitter for synchronous networks. Compare against the 8T49N286A variant if advanced features like Stratum 3E compliance or specific jitter filtering profiles are required. Verify that the required output drive strength and voltage levels match the load requirements of the downstream components.

Application Specific Clock/Timing Part Context

This part belongs to the 8T49N286 family of Universal Frequency Translators. It is distinct from the 8T49N286A which may offer enhanced specifications or additional features. The 'NLGI8' suffix indicates the RoHS-compliant, lead-free version in a tape-and-reel packaging format suitable for automated surface-mount assembly.

Application Specific Clock/Timing Replacement Considerations

Direct pin-to-pin replacements within the same family include other 8T49N286 variants with different frequency plans. For upgraded performance, consider the 8T49N286A series, but verify software compatibility and feature set differences. Cross-reference with IDT legacy part numbers if migrating from older Intersil/Renesas designs.
