Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 2.5V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 3.2x2.5 mm 4-SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 19.98 MHz clock signal is required with low-voltage compatibility. The LVCMOS output ensures direct interfacing with standard digital logic families without additional level shifting. The enable pin allows for power management optimization in battery-operated or sleep-mode capable applications.

Oscillators Part Context

This part belongs to the 25QHTF32 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized small form factor. The 'OE' suffix typically denotes the presence of an output enable feature, distinguishing it from basic continuous-output variants.

Oscillators Replacement Considerations

Direct substitutes must match the 19.98 MHz frequency, 2.5V operating voltage, LVCMOS output type, and 3.2x2.5mm 4-SMD package. Verify equivalent electrical parameters such as phase noise and jitter specifications to ensure functional compatibility in timing-sensitive applications.
