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 4-SMD footprint matches the PCB layout constraints. Cross-reference the datasheet for operating temperature range specifications to guarantee reliability under intended environmental conditions.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable pin offers power management flexibility for systems requiring dynamic clock control. Consider the small form factor of the 4-SMD package for space-constrained designs. Validate that the 28.228 MHz frequency meets the specific data rate or clock division needs of the application.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of standard crystal oscillators. The series typically offers various frequencies within a consistent 1.8V LVCMOS format. Similar parts in the lineup include variants like 18QHTF21-37.888-OE and 18QHTF21-13.584-OE, differing primarily in output frequency while maintaining identical electrical and mechanical characteristics.

Oscillators Replacement Considerations

Direct substitutes must match the 28.228 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and enable/disable logic polarity. Check if alternative manufacturers offer equivalent timing performance and temperature stability ratings.
