8T49N004A-067NLGI8

Overview

The 8T49N004A-067NLGI8 is a programmable clock generator from the FemtoClock NG series by Renesas Electronics. It operates at a maximum frequency of 156.25MHz with one circuit and a 1:4 input-to-output ratio. The device features differential LVPECL outputs and accepts crystal inputs. It functions within a supply voltage range of 2.375V to 3.465V and supports an operating temperature range of -40°C to 85°C. The component is housed in a 32-VFQFN package with an exposed pad.

Feature Summary

• Integrates a PLL with bypass functionality for flexible clock generation.
• Provides low-jitter LVPECL output signals for high-speed data transmission.
• Supports crystal input configurations for precise frequency synthesis.

Applications

• High-speed serial communication interfaces
• Data center infrastructure equipment
• Telecommunications networking hardware

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the FemtoClock NG family. Confirm current availability status, as this part number may be subject to discontinuation notices or production lifecycle changes. Ensure compatibility with system voltage requirements before integration.

Selection Notes

Select this component when low jitter performance is critical for serial link integrity. The 156.25MHz frequency point suits specific interface standards requiring this exact rate. Consider the 32-VFQFN package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the FemtoClock NG series, designed for applications demanding superior jitter attenuation. It complements other Renesas timing solutions by offering a balance of programmability and performance in a compact surface-mount package suitable for dense electronic assemblies.

Replacement Considerations

Consult the official FemtoClock NG ordering guide for cross-reference information. Verify if alternative suffixes or updated series members provide equivalent specifications and pinouts for direct replacement scenarios.
