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 2.0x1.6mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a fixed 24.309438 MHz reference is required for LVCMOS-compatible digital logic. Consider the 1.8V operating voltage constraint and the need for active enable/disable control. Evaluate the small form factor suitability for space-constrained printed circuit board layouts compared to larger through-hole or standard SMD oscillator packages.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard crystal oscillators. The series offers various frequencies within a consistent 4-SMD no lead package format. These components are designed for applications requiring reliable frequency generation in consumer electronics and industrial equipment where size and low voltage operation are critical constraints.

Oscillators Replacement Considerations

Direct substitutes include other 24.309438 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson or SiTime. Verify pinout compatibility and electrical specifications including supply voltage and current consumption. Ensure the replacement maintains the same enable/disable logic polarity if present in the original design.
