Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance requirements against the official datasheet before purchase. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package dimensions fit the intended PCB footprint. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Oscillators Selection Notes

Select this component when a 39.0625 MHz clock source is required for LVCMOS-compatible digital circuits. The choice is driven by the need for low-voltage operation at 1.8V and the integration of a power-down feature. Consider the physical constraints of the 4-SMD package size relative to available board space. Evaluate thermal performance within the specified operating temperature range.
