Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator specifications. Confirm that the 4-SMD footprint matches your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Selection Notes

Select this component when a precise 101.75 MHz timing source is required with low power consumption capabilities. Consider the LVCMOS interface compatibility with downstream logic families. Evaluate the thermal performance within the operating temperature range. Assess the physical size constraints of the 4-SMD package against available board real estate.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount crystal oscillators. The series typically offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down feature. This family is designed for applications requiring reliable timing signals in compact electronic devices.

Replacement Considerations

Direct substitutes must match the 101.75 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics. Cross-reference with other manufacturers offering similar SMD oscillators if Mercury Electronics parts are unavailable.
