Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the presence of the power-down feature as documented. Ensure the 1.8V supply requirement aligns with target circuit design. Confirm package orientation markings match assembly specifications. Cross-reference the ±50ppm stability against application tolerance requirements before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-profile 2.0x1.6mm oscillator is required for 1.8V logic systems. The 14.3325 MHz frequency suits specific baud rate or division applications. Consider the ±50ppm stability limit for environmental variations. The standby capability is critical for battery-operated devices requiring extended sleep modes.

Oscillators Part Context

This part belongs to the Mercury 18QHTF series of surface-mount crystal oscillators. The series offers various frequencies and voltage options.
