8T49N1012-002NLGI

Overview

The 8T49N1012-002NLGI is a FemtoClock NG Universal Frequency Translator (UFT) manufactured by Renesas Electronics. It integrates a high-performance PLL with an on-chip EEPROM for configuration storage, eliminating the need for external configuration devices. The device supports flexible input and output clock formats, including LVDS, LVPECL, HCSL, and LVCMOS. It features low jitter performance suitable for demanding digital applications. The component operates within a supply voltage range of 2.375V to 3.465V and is available in a compact VFQFN package.

Feature Summary

• Integrated on-chip EEPROM for non-volatile configuration storage
• Supports multiple differential and single-ended output formats
• Low phase noise and jitter performance typical of FemtoClock NG series
• Flexible frequency synthesis capabilities with integer and fractional mode support

Applications

• High-speed data communication systems
• Server and storage infrastructure clocking
• Networking equipment timing solutions
• Industrial control system synchronization

Procurement Notes

Verify the specific suffix -002NLGI against official Renesas documentation to confirm pinout, packaging, and electrical characteristics. Ensure compatibility with existing board layouts and power supply requirements before procurement. Check for end-of-life notices or product change notifications that may affect long-term availability.

Selection Notes

Select this component when a universal frequency translator with integrated configuration memory is required. Compare jitter specifications and output drive strengths against target loads. Verify that the available input frequencies match the design requirements for the PLL loop filter configuration.

Part Context

This part belongs to the Renesas FemtoClock NG family, which provides programmable clock generators and translators. The 8T49N1012 variant specifically offers universal frequency translation capabilities, allowing it to replace multiple fixed-frequency clock generators in a design, thereby reducing bill of materials complexity.

Replacement Considerations

Consult the official Renesas selection guide for direct replacements within the 8T49N101x series. Verify pin-to-pin compatibility if substituting with other variants in the same package. Cross-reference with updated datasheets to ensure no functional changes due to manufacturing process updates.
