Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail is stable and within the specified limits to ensure reliable oscillator performance. Check the package footprint compatibility with your PCB layout to avoid assembly issues.

Oscillators Selection Notes

Choose this component when a precise 27.52 MHz reference is required in space-constrained designs. The 1.8V operation makes it suitable for modern low-power digital circuits. Ensure the application environment stays within the specified temperature range for consistent timing accuracy.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies with standardized LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down control feature, allowing for active standby modes to reduce power consumption during idle periods.

Oscillators Replacement Considerations

Direct substitutes must match the 27.52 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical specifications before swapping manufacturers.
