Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to prevent assembly issues.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for space-constrained applications. The enable/disable feature allows for dynamic power management in battery-operated devices. Verify that the 27.002 MHz frequency aligns with system timing requirements and that the package size fits within the available board area constraints.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers standard frequencies with LVCMOS outputs. The '18' prefix indicates the 1.8V operating voltage range, while '21' denotes the package type. The '-OE' suffix may indicate specific ordering or packaging variations defined by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes must match the 27.002 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pin compatibility and electrical characteristics such as phase noise and jitter if critical to the application. Consult manufacturer cross-reference lists for verified equivalents.
