8T49N004A-068NLGI

Overview

The Renesas 8T49N004A-068NLGI is a FemtoClock NG programmable clock generator designed for high-performance timing applications. It operates within a supply voltage range of 2.375V to 3.465V and supports a maximum frequency of 245.76MHz. The device features one circuit with a 1:4 input-to-output ratio, utilizing crystal input and LVDS/LVPECL differential outputs. Packaged in a 32-VFQFN exposed pad (5x5) surface-mount format, it functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Generates precise clock signals using the FemtoClock NG architecture for low-jitter performance
• Supports flexible configuration with programmable frequency synthesis capabilities
• Provides differential output interfaces compatible with LVDS and LVPECL standards

Applications

• High-speed data communication systems requiring stable clock distribution
• Networking equipment and telecommunications infrastructure timing
• Industrial control systems needing precise synchronization

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm RoHS3 compliance and check for specific package labeling changes documented in recent PCNs. Ensure storage conditions respect MSL Level 3 limits to prevent moisture damage prior to soldering. Review end-of-life notices as availability may be restricted.

Selection Notes

Select this component when low jitter and programmability are critical for system timing integrity. Ensure the design accommodates the 32-VFQFN thermal requirements and 2.375V–3.465V power rails. Validate that the 1:4 output ratio meets the target load distribution needs without additional buffering.

Part Context

Part of the FemtoClock NG family, offering advanced jitter attenuation and flexibility. It serves as a specialized timing solution within Renesas' broader portfolio of clock generators and frequency synthesizers, targeting applications demanding superior signal integrity.

Replacement Considerations

Check for direct pin-compatible alternatives within the 8T49N004 series. Verify if updated revisions or successor models from Renesas offer improved availability while maintaining electrical compatibility.
