Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm the exact enable/disable pin configuration and voltage tolerance. Ensure the 4-SMD no-lead footprint matches the target PCB land pattern. Confirm that the 1.8V supply requirement aligns with the system's power rail before procurement.

Oscillators Selection Notes

Select this component when a precise 33.8688 MHz clock source is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage constraint during power budgeting. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs where clock gating is necessary to extend operational life.

Oscillators Part Context

This part belongs to the 18QHTF series of quartz crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a small form factor. The '18' prefix likely indicates the 1.8V supply variant, while 'QHTF' denotes the specific package and performance class within the manufacturer's oscillator lineup.

Oscillators Replacement Considerations

Direct substitutes include other 33.8688 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and enable/disable logic polarity. Alternative parts must match the electrical specifications and physical dimensions to ensure board-level interchangeability without redesign.
