8T49N008A-044NLGI

Overview

The 8T49N008A-044NLGI is a programmable clock generator from the FemtoClock NG series by Renesas Electronics. It features one circuit with a maximum frequency of 625MHz and an input-to-output ratio of 1:8. The device accepts differential inputs in LVPECL, LVDS, or HCSL formats and provides eight LVPECL outputs. It operates on a supply voltage between 2.375V and 3.465V within a temperature range of -40°C to 85°C. The component is housed in a 32-VFQFN exposed pad package.

Feature Summary

• Generates up to eight independent LVPECL output clocks from a single input source
• Utilizes FemtoClock NG PLL technology for low jitter performance
• Includes bypass capability for direct signal routing when required

Applications

• High-speed serial link clock distribution
• Network infrastructure equipment timing
• Test and measurement instrumentation
• Data center server backplanes

Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct output configuration and packaging. Confirm current availability status as this product line may have discontinuation notices. Cross-reference the part number with the manufacturer's latest documentation to validate RoHS compliance and environmental specifications before procurement.

Selection Notes

Select this component when eight LVPECL outputs are required from a single differential reference. Ensure the system design supports the 2.375V to 3.465V supply range. Verify that the input signal levels match the supported LVPECL, LVDS, or HCSL options. Consider the 32-VFQFN package constraints for PCB layout and thermal management requirements.

Part Context

This device belongs to the FemtoClock NG family, designed for high-performance clock generation and translation. It serves as a key component in systems requiring precise timing and low phase noise. The 8T49N008 variant specifically addresses applications needing multiple synchronized outputs derived from a single reference clock source.

Replacement Considerations

Consult the official replacement guide for compatible alternatives. Verify pinout compatibility and electrical parameter equivalence before substitution.
