8T49N008A-050NLGI8

Overview

The Renesas Electronics Corporation 8T49N008A-050NLGI8 is a clock generator IC designed for high-performance timing applications. It operates within a frequency range up to 156.25MHz and supports LVDS and LVPECL output formats. The device is housed in a 40-VFQFN package with an exposed pad, suitable for surface mount assembly. It functions as a PLL-based frequency synthesizer, providing precise clock distribution for digital systems requiring low jitter and stable frequency generation.

Feature Summary

• Supports LVDS and LVPECL output interface standards
• Integrated PLL frequency synthesis capability
• Surface mount 40-VFQFN package design

Applications

• Digital signal processing systems
• Communication equipment timing
• Industrial control circuits

Procurement Notes

Verify the specific suffix NLGI8 against official Renesas documentation to confirm exact temperature range and packaging specifications. Ensure compatibility with LVDS/LVPECL load requirements. Cross-reference the 40-VFQFN footprint with PCB design guidelines. Confirm RoHS compliance status through current datasheets before integration into production designs.

Selection Notes

Select this component when LVDS or LVPECL outputs are required alongside a 156.25MHz maximum frequency. The 40-VFQFN package suits space-constrained surface mount designs. Evaluate thermal performance due to the exposed pad requirement. Ensure system power supply voltages align with the device specifications for reliable PLL operation and output drive strength.

Part Context

This part belongs to the Renesas FemtoClock family of clock generators. These devices are engineered for low-jitter performance in data communication and computing applications. The 8T49N series typically integrates programmable features for flexible frequency generation, serving as critical timing sources for high-speed serial links and memory interfaces.

Replacement Considerations

Consult official substitution lists for direct pin-compatible alternatives. Verify electrical parameters such as output voltage levels and jitter specifications match the original design requirements. Check package dimensions and thermal characteristics to ensure mechanical fit.
