8T49N1012-008NLGI8

Overview

The 8T49N1012-008NLGI8 is a clock generator and support product from the Renesas FemtoClock NG family. It functions as an ultra-low jitter clock synthesizer designed for high-speed serial applications. The device integrates a Phase-Locked Loop (PLL) to generate precise clock signals from reference inputs, supporting multiple output configurations. It is engineered to meet stringent jitter requirements for standards such as PCI Express and SATA. The component operates within a standard industrial temperature range and utilizes an I2C interface for configuration.

Feature Summary

• Ultra-low RMS phase jitter performance suitable for high-speed data transmission
• Integrates FemtoClock NG PLL technology for low-noise clock synthesis
• Supports multiple output formats including LVDS and LVPECL
• Configurable via I2C programming interface

Applications

• PCI Express Gen1/Gen2/Gen3 compliant systems
• SATA/SAS storage interfaces
• High-speed networking equipment
• Server and workstation motherboard clocking

Procurement Notes

Verify the specific order code suffix against the official Renesas datasheet to confirm factory pre-programmed frequency settings. Ensure compatibility with existing PCB layout requirements for the package type. Confirm RoHS compliance status through current manufacturer documentation before procurement.

Selection Notes

Select this component when ultra-low jitter is critical for signal integrity in high-speed serial links. Compare internal VCO specifications and output drive strength against system requirements. Verify that the available factory presets or I2C configurability align with the target design frequencies.

Part Context

This part belongs to the 8T49N1012 series of clock generators. It is distinct from evaluation boards like EVK-8T49N1012 and other variants such as 8T49N241 or 8T49N286A which may have different pin counts or feature sets. The -008NLGI8 suffix denotes specific packaging and factory programming.

Replacement Considerations

Consult the Renesas cross-reference guide for direct replacements. Similar devices in the FemtoClock NG family may offer compatible functionality but require verification of pinout and electrical parameters.
