Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits defined in the official datasheet to ensure reliable oscillator performance.

Oscillators Selection Notes

Select this component when a precise 4.6 MHz reference is required for low-power applications. Ensure the host circuit supports LVCMOS logic levels and can accommodate the 2.0x1.6mm surface-mount footprint. Consider the power-down feature if dynamic power management is necessary for the target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltages, typically utilizing standard XO configurations. The 'PD' suffix indicates the inclusion of a power-down pin or function, distinguishing it from basic continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 4.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pin compatibility and thermal characteristics. Cross-reference with other Mercury Electronics models in the same series for potential functional equivalents.
