8T49N004A-058NLGI

Overview

The 8T49N004A-058NLGI is a clock generator from the FemtoClock NG series manufactured by Renesas Electronics Corporation. It features one circuit with a maximum frequency of 300MHz and operates on a 2.375V to 3.465V supply voltage. The device accepts HCSL, LVDS, or LVPECL differential inputs and provides four LVPECL differential outputs in a 1:4 ratio. Packaged in a 32-VFQFN with an exposed pad, it supports I2C programming and includes a PLL with bypass functionality for flexible clock distribution applications.

Feature Summary

• Supports input levels including HCSL, LVDS, and LVPECL
• Generates four LVPECL differential output channels
• Operates within a 2.375V to 3.465V power supply range
• Integrated PLL with bypass capability

Applications

• High-speed data communication systems requiring low jitter
• Networking equipment utilizing LVPECL interfaces
• Industrial control systems operating between -40°C and 85°C

Procurement Notes

This component is listed as obsolete with a final shipment date of July 11, 2026. Verification of remaining stock availability through authorized distributors is required before procurement planning. Ensure compliance with RoHS3 standards and check for any pending product change notifications regarding assembly sites or labeling updates.

Selection Notes

Select this part when a single-input, four-output LVPECL clock generator is needed with support for multiple input logic levels. Verify that the 300MHz maximum frequency meets system requirements. Confirm compatibility with the 32-VFQFN package footprint and ensure the design accommodates the exposed pad thermal requirements.

Part Context

The 8T49N004A-058NLGI belongs to the FemtoClock NG family, designed for precision timing applications. It shares the base 8T49N004 architecture but is distinguished by its specific output configuration and input level support. This model serves as a specialized solution for converting various input signals into synchronized LVPECL clocks.

Replacement Considerations

As the part is obsolete, verify if the 8T49N004A-058NLGI8 variant offers identical electrical specifications and pinout compatibility. Consult official substitution guides for potential cross-model alternatives within the FemtoClock NG series.
