Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct pinout and electrical specifications. Confirm that the requested part matches the exact frequency and package dimensions required for the target PCB layout. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-profile surface mount oscillator is required for 1.8V logic systems. The choice depends on the need for a standard XO with integrated enable/disable control via the standby pin. Ensure the thermal environment stays within the specified -40°C to 85°C operational range for reliable performance.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronic, a supplier specializing in quartz crystals and oscillators. The series offers various frequencies and packages, providing standardized timing solutions for modern electronic designs requiring small form factors and low power consumption.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinouts but different frequencies, such as 18QHTF21-6.760-PD or 18QHTF21-96.768-PD. Verify that any replacement maintains the same 1.8V supply requirement and LVCMOS output characteristics.
