Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V to 3.3V supply voltage range aligns with your system's power rails. Ensure the LVCMOS output compatibility matches the input specifications of the receiving component. Check for any specific ordering suffixes that may indicate different packaging or testing standards.

Oscillators Selection Notes

Select this oscillator when a small form factor and low voltage operation are critical. Consider the enable/disable feature if power efficiency during idle states is a priority. Evaluate the thermal performance within the specified operating temperature range for your application environment. Compare alternative frequencies from the same series if the exact 14.85 MHz is not strictly required.

Oscillators Part Context

This component belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series is characterized by its small footprint and support for various supply voltages. Similar models in the series include variants with different frequencies such as 19.200 MHz and 37.888 MHz, sharing the same package and electrical interface characteristics.

Oscillators Replacement Considerations

Direct replacements must match the 14.85 MHz frequency, LVCMOS output, and 4-SMD package. Verify that substitute components support the same enable/disable control mechanism and voltage range. Cross-reference pinouts to ensure compatibility with existing PCB layouts.
