Oscillators Procurement Notes

Verify the specific frequency tolerance and package dimensions against the official datasheet before integration. Confirm that the 1.8V supply requirement aligns with the target circuit design. Ensure the LVCMOS output compatibility matches the receiving logic levels. Check the operating temperature range suitability for the intended environment.

Oscillators Selection Notes

Select this component when a precise 14.318181 MHz clock source is required with low power consumption. The 1.8V operation makes it suitable for modern low-voltage digital systems. The standby feature allows for energy savings during idle periods. Consider the ±50ppm stability for applications requiring moderate frequency accuracy.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small footprint. The 'PD' suffix indicates the inclusion of a power-down or standby functionality, distinguishing it from continuous-operation variants.

Oscillators Replacement Considerations

Direct substitutes must match the 14.318181 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent frequency stability and temperature range specifications. Cross-reference pinout configurations to ensure compatibility without circuit modification.
