Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure the selected variant matches the required supply voltage and package dimensions. Confirm that the manufacturer's specifications align with your thermal and electrical constraints. Cross-reference the part number with official distributor catalogs to ensure authenticity and availability.

Oscillators Selection Notes

Select this oscillator when a small form factor and low power consumption are critical. The LVCMOS output is suitable for direct interfacing with standard digital logic. Consider the operating temperature range if the application involves harsh environmental conditions. Verify that the 1.8V to 3.3V supply range matches your system's power rails.

Oscillators Part Context

This component belongs to the 18QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and package sizes to accommodate different design needs. The 18QHTF21 variant specifically utilizes a 2.0 x 1.6 mm footprint, making it one of the smaller options in the lineup for high-density PCB designs.

Oscillators Replacement Considerations

Direct substitutes may include other 24.575 MHz LVCMOS oscillators in a 4-SMD no-lead package with similar dimensions. Ensure replacement parts match the supply voltage range and output logic type. Verify that alternative components meet the same temperature and performance specifications.
