Procurement Notes

Verify current availability status as supply may be limited or subject to factory special orders. Confirm RoHS3 compliance and lead times directly with authorized distributors. Ensure ordering suffixes match specific voltage and package requirements. Check for product change notifications regarding assembly sites or marking updates before finalizing procurement plans.

Selection Notes

Select this model when low phase jitter performance is critical for system stability. Verify that the required output frequencies and drive strengths align with the device's specifications. Consider the I2C programming flexibility for multi-frequency designs. Evaluate thermal management needs based on the operating temperature range and power consumption characteristics.

Part Context

This component belongs to the 8T49N240 series of clock synthesizers. It shares architectural similarities with other FemtoClock NG devices but offers specific configuration options defined by the -035 order code. The NLGI8 suffix indicates the tape and reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the FemtoClock portfolio. Verify pin-to-pin compatibility and electrical parameter equivalence before replacing. Note that newer generations may offer enhanced features but require design review.
