8T49N006A-000NLGI

Overview

The 8T49N006A-000NLGI is a programmable clock generator from the FemtoClock NG family. It features six selectable LVPECL or LVDS outputs and utilizes fourth-generation PLL technology. The device accepts differential inputs including LVPECL, LVDS, and HCSL. It operates with a VCO range of 1.92GHz to 2.5GHz and supports I2C programming. The component functions as a low RMS phase jitter clock synthesizer suitable for high-speed digital applications.

Feature Summary

• Generates up to six output frequencies using fourth-generation FemtoClock NG PLL technology
• Supports flexible input levels including LVPECL, LVDS, and HCSL via CLK/nCLK pair
• Provides selectable LVPECL or LVDS output signaling configurations
• Enables register programming through an I2C interface

Applications

• PCI Express (Gen2/Gen3) systems requiring compliant clock generation
• High-speed networking equipment utilizing differential signaling
• Servers and storage subsystems needing low jitter clock synthesis
• Test and measurement instruments requiring precise frequency translation

Procurement Notes

Verify the specific suffix '000NLGI' against official Renesas documentation to confirm exact factory pre-programmed frequency sets and package details. Confirm current lifecycle status as this series may be subject to discontinuation notices. Ensure compatibility with required supply voltages and I2C addressing before integration into new designs.

Selection Notes

Select this component when six differential outputs are required with ultra-low jitter performance. Compare against the 8T49N004I for four-output needs or the 8T49N008I for eight-output requirements. Verify that the internal crystal oscillator or external reference input matches the target application's frequency specifications and jitter budget constraints.

Part Context

This part belongs to the FemtoClock NG family of ultra-low jitter clock generators. It shares architectural similarities with the 8T49N004I and 8T49N008I models, differing primarily in output count. The series is designed for applications demanding strict phase noise compliance in high-speed serial data transmission environments.

Replacement Considerations

Consult official substitution lists for equivalent timing solutions. Verify pinout compatibility if replacing legacy IDT variants. Ensure software configuration tools support the specific device variant during migration.
