8T49N286A-999NLGI

Overview

The 8T49N286A-999NLGI is a Universal Frequency Translator from the FemtoClock NG series, manufactured by Renesas Electronics. It functions as a clock synthesizer and jitter cleaner with one circuit, supporting input formats including HCSL, LVCMOS, LVDSM, LVHSTL, LVPECL, and crystals. The device offers eight outputs in HCSL, LVCMOS, LVDS, or LVPECL configurations. It operates on a supply voltage of 2.375V to 3.465V and supports frequencies up to 1GHz. Packaged in a 72-VFQFN exposed pad (10x10mm), it complies with GR.1244 Stratum standards.

Feature Summary

• Supports 5:8 input-to-output ratio for flexible frequency translation
• Accepts differential inputs and provides differential outputs
• Integrated PLL with bypass capability for low-jitter performance
• Compliant with Telcordia GR.1244-CORE Stratum specifications

Applications

• Telecommunications infrastructure requiring precise timing
• Data center synchronization systems
• High-speed serial communication interfaces

Procurement Notes

Verify RoHS3 compliance and MSL level 3 (168 hours) before handling. Confirm package type matches design requirements, as variations exist between reel and tray packaging within the same part family. Check for active status and availability constraints due to potential supply limitations.

Selection Notes

Select this component when a single Universal Frequency Translator with 5:8 I/O ratio is required. Ensure input signal types match supported formats like LVPECL or crystal. Verify that the 72-VFQFN package fits the PCB layout constraints and thermal requirements for operation between -40°C and 85°C.

Part Context

This part belongs to the 8T49N286A series, which includes variants such as 8T49N286A-003NLGI8 and 8T49N286A-998NLGI8. These devices share the FemtoClock NG architecture but differ in output configurations, packaging, and specific ordering suffixes that define electrical or mechanical attributes.

Replacement Considerations

Direct substitutes are not explicitly listed for this specific suffix. Similar devices in the 8T49N241 or 8T49N287 families may offer comparable functionality but require verification of pin compatibility and electrical parameters.
