8T49N008A-059NLGI

Overview

The 8T49N008A-059NLGI is a programmable clock generator from the FemtoClock NG series by Renesas Electronics Corporation. It features an LVPECL input and eight LVDS outputs, supporting frequencies up to 300 MHz. The device operates on a single 2.5V or 3.3V supply within a 32-VFQFN exposed pad package. Designed for low jitter performance, it integrates a PLL with bypass capability and supports HCSL, LVDS, and LVPECL inputs. The component is currently marked as obsolete by the manufacturer.

Feature Summary

• Eight LVDS output channels
• Maximum frequency of 300 MHz
• Single 2.5V or 3.3V power supply
• 32-VFQFN (5x5) package

Applications

• High-speed data communication systems
• Networking equipment clock distribution
• Server and storage subsystem timing

Procurement Notes

This part number is officially listed as obsolete by Renesas Electronics. Verification of current availability requires checking authorized distributors for last-time-buy status or surplus stock. Confirm RoHS3 compliance and MSL rating before procurement planning.

Selection Notes

Select this component when eight differential LVDS outputs are required at frequencies up to 300 MHz. Ensure the design accommodates the 32-VFQFN package thermal requirements. Verify that the input signal matches the supported HCSL, LVDS, or LVPECL standards.

Part Context

The 8T49N008A-059NLGI belongs to the FemtoClock NG family, which focuses on low-jitter clock generation. Similar models in the series include the 8T49N004A and 8T49N008A variants, differing primarily in output count and specific configuration suffixes.

Replacement Considerations

Consult the official Renesas FemtoClock NG replacement guide for direct pin-compatible or functionally equivalent alternatives. Cross-reference with the 8T49N008A series for potential upgrades.
