Application Specific Clock/Timing Procurement Notes

Verify the specific datasheet revision and pinout configuration against your schematic before integration. Confirm that the 48-VQFN thermal pad connection requirements match your PCB layout guidelines. Ensure the power supply decoupling strategy meets the high-frequency switching demands of the LVPECL outputs. Check for any recent Product Change Notifications (PCNs) related to this part number to ensure long-term availability and consistency.

Application Specific Clock/Timing Selection Notes

Select this component when a crystal reference is required to generate multiple synchronized LVPECL clocks. It is suitable for designs needing low jitter performance in networking contexts. Consider the 48-pin QFN footprint for space-constrained boards. Evaluate the 2.375V to 3.465V supply range compatibility with existing system rails. Compare against other SM8060xx variants if different output counts or voltage levels are needed.
