Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 19.28 MHz specification. Confirm the 1.8V operating voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout requirements before finalizing procurement.

Oscillators Selection Notes

Select this component when a 19.28 MHz reference is needed for 1.8V logic interfaces. Consider the small 2.0x1.6mm form factor for space-constrained designs. Evaluate the LVCMOS compatibility with downstream digital inputs to ensure signal integrity without additional level shifting.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. These components are designed for applications requiring reliable frequency control in compact electronic assemblies.

Oscillators Replacement Considerations

Direct substitutes must match the 19.28 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics before cross-referencing other manufacturers' offerings.
