Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator specifications. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a precise 46.49596 MHz reference is required in space-constrained designs. The choice is driven by the need for low-power consumption via the standby mode and compatibility with 1.8V logic families. Consider the small form factor for high-density board layouts where larger packages are unsuitable.
