8T49N004A-063NLGI

Overview

The 8T49N004A-063NLGI is a programmable clock generator from the FemtoClock NG series, manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.375V to 3.465V and supports an input frequency of up to 245.76MHz. The device features a single circuit with a 1:4 input-to-output ratio, providing differential LVDS or LVPECL outputs. It is housed in a 32-VFQFN package with an exposed pad, designed for surface-mount installation. The component functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Single-circuit programmable clock generator with 1:4 input-to-output ratio
• Supports differential LVDS and LVPECL output types
• Operates on a 2.375V to 3.465V power supply
• Available in a compact 32-VFQFN (5x5) package

Applications

• High-speed data communication systems requiring low-jitter clocking
• Networking equipment utilizing PLL-based frequency synthesis
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify the specific suffix '063' against official Renesas documentation to confirm the exact output frequency configuration, as suffixes define programming parameters. Confirm current lifecycle status, as similar models in this series may have discontinued statuses. Ensure compatibility with the required 32-VFQFN footprint and moisture sensitivity level during procurement planning.

Selection Notes

Select this component when a single PLL with four differential outputs is required for jitter attenuation or frequency multiplication. Compare the 245.76MHz maximum input frequency against system requirements. Evaluate the 32-VFQFN package size constraints against available PCB real estate. Verify that the 2.375V to 3.465V supply range aligns with the target board's power delivery network.

Part Context

This part belongs to the FemtoClock NG family, which specializes in low-jitter clock generation and distribution. The 8T49N004A variant typically offers flexible programming options for various clock frequencies. It serves as a critical timing element in high-performance digital systems where signal integrity and precise frequency synthesis are mandatory.

Replacement Considerations

Check for direct pin-compatible substitutes within the 8T49N004A series with different suffixes for varied frequencies. Verify if newer revisions of the FemtoClock NG family offer improved performance metrics while maintaining the same package outline.
