Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application environment before procurement. Ensure that the 1.8V supply voltage aligns with the system power rails. Confirm that the LVCMOS output swing is compatible with the receiving logic inputs to guarantee signal integrity and reliable operation within the designed circuit parameters.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is required alongside a specific 27.115 MHz frequency. Consider the small 2.0x1.6 mm footprint for space-constrained designs. Evaluate the need for enable/disable control features to optimize system power consumption during idle states compared to continuously running oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD no-lead form factor. The series typically supports 1.8V operation and LVCMOS outputs, providing a consistent platform for designers needing reliable timing solutions in compact electronic assemblies across consumer and industrial sectors.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-15.300-OE or 18QHTF21-37.300-OE, provided the system timing requirements allow for frequency adjustment.
