Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and frequency tolerances. Confirm that the 1.8V supply requirement aligns with the target system design. Ensure the LVCMOS output logic matches the receiving component's input specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise frequency stability. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Consider the enable pin feature if dynamic power saving is necessary for the application environment.

Oscillators Part Context

This part belongs to the QHTF series of quartz crystal oscillators from Mercury Electronics. The series is characterized by small form factors and low power consumption, catering to modern portable electronic devices. Mercury Electronics has extensive experience in frequency control products since 1973.

Oscillators Replacement Considerations

Check for direct substitutes within the same series or family that match the 37.875 MHz frequency and 1.8V supply. Verify pinout compatibility and package dimensions to ensure mechanical fit without redesigning the PCB layout.
