8T49N283C-999NLGI

Overview

The 8T49N283C-999NLGI is a FemtoClock Dual UFT clock generator manufactured by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and supports output frequencies up to 1GHz. The device features one circuit with a 1:8 input-to-output ratio, utilizing crystal inputs and providing LVCMOS and LVPECL outputs. It is housed in a 56-VFQFN package with an exposed pad, designed for surface mount installation across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual Universal Frequency Translator (UFT) architecture
• Supports differential LVPECL and single-ended LVCMOS outputs
• Maximum output frequency of 1GHz
• Integrated I2C programming interface

Applications

• High-speed data communication equipment
• Network infrastructure timing solutions
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'NLGI' against the official datasheet to confirm packaging details and factory configuration. Confirm moisture sensitivity level (MSL) requirements prior to storage and handling. Ensure the ordering quantity aligns with the manufacturer's standard reel or tray specifications.

Selection Notes

Select this component when dual independent frequency synthesis paths are required from a single reference source. Verify that the 56-VFQFN footprint matches the PCB layout constraints. Confirm that the 1:8 ratio and supported output voltage levels meet the downstream load requirements.

Part Context

This part belongs to the 8T49N283C series within the FemtoClock NG family. It shares architectural similarities with other universal frequency translators but is distinguished by its specific dual-output bank configuration and 56-pin form factor.

Replacement Considerations

Consult the official replacement guide for direct pin-compatible alternatives. Verify electrical parameter compatibility before substituting with other models in the 8T49N series.
