Oscillators Procurement Notes

Verify the specific frequency tolerance and stability specifications against the official datasheet before integration, as these parameters are critical for system timing integrity. Confirm that the 1.8V supply requirement aligns with your target circuit design. Ensure the 4-SMD package dimensions fit within your board layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate the power-down functionality behavior with your specific load conditions.

Oscillators Selection Notes

Select this component when a 124.992 MHz frequency is specifically required alongside LVCMOS output compatibility. Consider the 1.8V operating voltage to ensure it matches your system's power rails. The compact 2.0x1.6mm package makes it suitable for applications where board space is limited. Evaluate the need for the standby feature if power management during idle states is a priority for your design.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which focuses on standard crystal oscillators. The '18' prefix typically indicates the 1.8V supply voltage, while 'QHTF' denotes the series type. The '-PD' suffix confirms the inclusion of a power-down function. Mercury Electronics specializes in frequency control products, offering various packaging and voltage options within this family.

Oscillators Replacement Considerations

Direct substitutes include other 124.992 MHz LVCMOS oscillators from Mercury Electronics such as the 18QHTF22-124.992-PD, which may offer different stability ratings. Verify pinout compatibility and package dimensions when considering alternatives from other manufacturers to ensure seamless integration without PCB redesign.
