• Embedded controller clock inputs

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure 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 stable 25.2235 MHz reference is required with low power consumption capabilities. The LVCMOS output is appropriate for standard digital logic families. Consider the operating temperature range and stability specifications if the application involves harsh environmental conditions or high precision timing needs.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, designed for general electronic applications. The model number indicates the specific frequency and package type within the manufacturer's lineup. It serves as a standalone clock source for integrated circuits requiring external oscillation.

Oscillators Replacement Considerations

Direct substitutes must match the 25.2235 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before cross-referencing with other manufacturers' offerings.
