• Embedded electronics requiring low profile oscillators

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions provided in the official datasheet to prevent mounting issues.

Oscillators Selection Notes

Select this component when a 47.2 MHz clock source is required with LVCMOS outputs. Consider the 1.8V operating voltage and the need for power-down capabilities. The small form factor makes it suitable for space-constrained designs. Verify temperature stability requirements against the standard commercial range specifications.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies including 51.2 MHz, 63.2 MHz, and 68.665 MHz. All variants share similar packaging and electrical characteristics, differing primarily in their nominal output frequency and specific ordering suffixes.

Oscillators Replacement Considerations

Compatible substitutes within the same series include 18QHTF21-51.200-PD, 18QHTF21-63.200-PD, and 18QHTF21-68.665-PD. These parts share identical package types and voltage levels but operate at different frequencies. Ensure the new frequency meets the system timing requirements before substitution.
