Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's official documentation to confirm the exact enable/disable configuration and tolerance specifications. Ensure the required operating temperature range aligns with the component datasheet before procurement. Cross-reference the part number with authorized distributors to validate authenticity and current availability status.

Oscillators Selection Notes

Select this component when a 47.99 MHz clock signal is required with low-voltage LVCMOS compatibility. The 1.8V supply requirement dictates system power rail compatibility. The enable/disable feature allows for power management integration. Verify that the 4-SMD no-lead footprint matches the PCB design constraints and thermal requirements.

Oscillators Part Context

This model belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies within the same physical package. The 'OE' suffix typically denotes specific operational characteristics or packaging variants defined by the manufacturer. This component serves as a primary clock source for electronic circuits requiring stable frequency generation.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series models from Mercury Electronics with identical pinout and voltage specifications but different frequencies, such as 18QHTF21-44.200-OE or 18QHTF21-21.200-OE, provided the frequency difference is acceptable for the application.
