Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for your environment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 22.857142 MHz reference. The LVCMOS output is appropriate for standard digital logic families. Consider the standby feature if power efficiency during idle states is a priority. Verify that the small form factor fits within the available board space constraints.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent electrical characteristics. The 'PD' suffix typically indicates a specific packaging or tape-and-reel configuration, though exact details require datasheet confirmation. It is designed for high-volume consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 22.857142 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Cross-reference with other manufacturers offering identical pinouts and electrical specs. Ensure thermal and mechanical compatibility before swapping components.
