8T49N008A-038NLGI8

Overview

The 8T49N008A-038NLGI8 is a programmable clock generator from the FemtoClock NG family, manufactured by Renesas Electronics. It features an integrated Phase-Locked Loop (PLL) for frequency synthesis and jitter attenuation. The device supports multiple output configurations with selectable LVPECL or LVDS signal standards across eight output channels. Designed for high-performance timing applications, it operates within a standard industrial temperature range of -40°C to +85°C. The component utilizes an I2C interface for configuration and register programming, allowing customization of output frequencies and phases relative to input references.

Feature Summary

• FemtoClock NG PLL technology for low phase jitter performance
• Eight configurable outputs supporting LVPECL or LVDS standards
• I2C programming interface for flexible frequency and phase configuration
• Industrial operating temperature range (-40°C to +85°C)

Applications

• High-speed serial communication interfaces requiring precise clocking
• Data center infrastructure and server systems
• Telecommunications equipment needing jitter-cleaned reference clocks

Procurement Notes

Verify current availability status as this part number may be subject to discontinuation or limited supply. Confirm that the specific order code suffix matches the required factory pre-programmed configuration. Check for alternative packages or updated revisions if original stock is unavailable. Ensure compliance with RoHS directives for environmental regulations.

Selection Notes

Select this component when low RMS phase jitter and flexible output drive strengths are required. Compare against other FemtoClock NG variants based on specific output count and voltage level requirements. Verify that the internal VCO range and divider settings support the desired input-to-output frequency ratios. Consider power consumption differences between LVPECL and LVDS output configurations.

Part Context

This part belongs to the Renesas 8T49N008A series of programmable clock generators. It is part of the broader FemtoClock portfolio designed for high-speed data transmission applications. The '038' suffix indicates a specific factory-programmed configuration for output frequencies and input reference compatibility.

Replacement Considerations

Consult Renesas documentation for direct pin-compatible replacements within the 8T49N008A family. Evaluate similar FemtoClock NG devices such as the 8T49N028 or 8T49N105A if configuration flexibility differs. Verify electrical compatibility before substituting with generic clock synthesizers.
