Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V operating voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package dimensions fit within the designated PCB footprint constraints.

Oscillators Selection Notes

Select this component when a low-voltage LVCMOS oscillator is required for space-constrained designs. The enable/disable feature allows for power management optimization. Verify that the 3.319507 MHz frequency meets the specific system clocking needs without additional frequency multiplication.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and enable features. The 'OE' suffix typically denotes specific packaging or tape-and-reel configurations as defined by the manufacturer's ordering guide.

Oscillators Replacement Considerations

Direct substitutes must match the 3.319507 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Cross-reference part numbers such as 18QHTF21-3.319507-OE variants from other manufacturers only if pinout and electrical specifications are identical.
