Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet. Ensure the PCB layout accommodates the 2.0x1.6 mm package dimensions and soldering specifications for lead-free components to guarantee reliable performance.

Oscillators Selection Notes

Select this component when a precise 16.393 MHz reference is required in space-constrained applications. The LVCMOS interface ensures compatibility with standard digital logic families operating at 1.8V. Consider the standby feature if power efficiency during idle periods is a critical design parameter. Validate thermal performance within the intended operating temperature range.

Oscillators Part Context

This part belongs to the 18QHTF21 series of ultra-small crystal oscillators from Mercury Electronics. The series is characterized by its miniature 2.0x1.6 mm package and low voltage operation, targeting modern portable electronics. The 'PD' suffix indicates the inclusion of a power-down control function, distinguishing it from standard continuous-output variants within the same form factor family.

Oscillators Replacement Considerations

Direct replacements must match the 16.393 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6 mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter against the original specification. Cross-reference with other manufacturers offering similar small-footprint XO solutions ensuring identical mechanical and electrical parameters.
