Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity and RoHS compliance status prior to integration. Check for relevant Product Change Notifications (PCN) regarding assembly site changes or marking updates. Ensure compatibility with existing system voltage levels and I2C bus configurations before final procurement decisions.

Selection Notes

Select this component when four independent differential outputs are required with low jitter specifications. Consider the FemtoClock NG architecture for superior phase noise compared to standard PLLs. Verify that the input reference frequency matches the device's supported range. Evaluate thermal requirements for the operating environment to ensure reliable performance within the specified temperature limits.

Part Context

This part belongs to the 8T49N008 family, which includes variants like the 8T49N008I. These devices are designed as crystal-to-clock generators with fanout buffer capabilities. The family shares common architectural features such as the FemtoClock NG core and I2C configurability, differing primarily in pre-programmed frequency sets and specific ordering suffixes.

Replacement Considerations

Direct substitutes include other members of the 8T49N008 family, such as the 8T49N008I. Cross-reference pinouts and electrical characteristics carefully. Verify that alternative parts support the same output types and voltage ranges. Consult official datasheets for any functional differences between specific order codes.
