8T49N006A-056NLGI

Overview

The 8T49N006A-056NLGI is a programmable clock generator from the FemtoClock NG series by Renesas Electronics Corporation. It features six selectable LVPECL or LVDS outputs and accepts differential input levels including LVPECL, LVDS, and HCSL. The device utilizes fourth-generation PLL technology with a VCO range of 1.9GHz to 2.55GHz. It operates on a full 2.5V or 3.3V power supply and supports I2C programming. The component is housed in a 32-VFQFN exposed pad package and functions within an ambient operating temperature range of -40°C to 85°C.

Feature Summary

• Generates up to six output frequencies from a single crystal or reference clock input using fourth-generation FemtoClock NG PLL technology.
• Supports flexible output configurations with selectable LVPECL or LVDS signal levels for diverse system requirements.
• Enables precise frequency selection via an I2C interface or hardware pins for predefined factory-programmed configurations.

Applications

• High-speed networking equipment requiring low jitter clock distribution
• Telecommunications infrastructure utilizing SONET/SDH standards
• Data center interconnects and server motherboards

Procurement Notes

Verify the specific ordering suffix against the official Renesas datasheet to ensure correct voltage, package, and temperature ratings. Confirm current availability status as components may be subject to discontinuation notices. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a design requires multiple differential clock outputs with low phase jitter characteristics. Ensure the application supports the required 2.5V or 3.3V supply rails. Verify that the I2C interface compatibility matches the system controller. Consider the 32-VFQFN package dimensions for PCB layout constraints.

Part Context

This part belongs to the FemtoClock NG family, designed for high-performance clock generation. It integrates advanced PLL technology to minimize phase noise. The device serves as a critical timing source for synchronous digital systems, replacing discrete oscillator solutions with a programmable integrated circuit.

Replacement Considerations

Consult the official Renesas replacement guide for direct substitutes. Verify pin-to-pin compatibility and electrical parameter equivalence. Check for updated manufacturing sites or packaging changes documented in Product Change Notices.
