Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer part number with official distributor catalogs to confirm current availability and authenticity.

Selection Notes

Select this oscillator when a precise 86.955 MHz reference is required for LVCMOS-compatible logic families. Consider the 1.8V supply constraint and the need for power-down capabilities. Evaluate the 2.0x1.6mm package size against available board space. Compare performance metrics such as phase noise and stability if available in official documentation to ensure suitability for the target application environment.

Part Context

This component belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics Ind. Co. Ltd. The series typically offers various frequencies and voltage options within a small form factor. The 'PD' suffix likely indicates the power-down feature. Mercury Electronics specializes in quartz crystal and oscillator manufacturing, providing frequency control solutions for electronic devices.

Replacement Considerations

Direct replacements must match the 86.955 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical characteristics. Consult official substitution lists from Mercury Electronics or authorized distributors for confirmed equivalent part numbers.
