Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure the correct voltage and package variant. Confirm that the LVCMOS output type matches the receiving logic family requirements. Check for any recent revisions to the enable/disable pin configuration or electrical specifications before finalizing the bill of materials.

Oscillators Selection Notes

Select this component when a precise 3.0625 MHz clock source is required with low power consumption capabilities. The 1.8V operating voltage makes it suitable for modern portable and battery-operated devices. Ensure the PCB layout supports the 4-SMD footprint and that the load conditions match the oscillator's specified parameters for accurate frequency stability.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which offers various frequencies within the same form factor. The series typically includes options for different supply voltages and output types. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though verification with official documentation is necessary to confirm exact handling characteristics.

Oscillators Replacement Considerations

Direct replacements must match the 3.0625 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical. Cross-reference with other Mercury parts in the 18QHTF21 series or equivalent industry-standard oscillators.
