Procurement Notes

Mouser currently reports this part number as not supplied in their region. The product may be subject to limited sales or factory special orders. Verification of current availability and lead times should be conducted directly with authorized distributors or the manufacturer before design finalization.

Selection Notes

This component is suitable for designs requiring low-jitter clock generation from high-frequency references. Ensure the PCB layout accommodates the VFQFN-40 package dimensions. Verify that the system power supply remains within the 2.375 V to 3.465 V range to maintain specified performance parameters.

Part Context

The 8T49N240 series belongs to Renesas' FemtoClock NG line, designed for universal frequency translation and jitter attenuation. This specific variant provides four outputs and is optimized for networking and communication infrastructure where precise timing and low phase noise are critical requirements.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Renesas technical support for direct replacements or cross-reference options based on specific electrical and pinout compatibility requirements.
