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 rail can maintain stable voltage under all operating conditions to ensure oscillator stability. Ensure the PCB layout accommodates the 4-SMD no-lead package dimensions accurately to prevent soldering defects.

Oscillators Selection Notes

Select this component when a 25.088 MHz clock source is required with low power consumption capabilities. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the thermal performance and environmental operating range if the application involves extreme temperatures or high-density board layouts.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options, designed for portable and space-constrained electronic applications. The 'PD' suffix indicates the inclusion of a power-down control feature, enhancing energy efficiency in battery-operated devices.

Oscillators Replacement Considerations

Direct substitutes must match the 25.088 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications with alternative manufacturers to ensure functional equivalence without circuit redesign.
