Oscillators Procurement Notes

Verify the specific suffix against official documentation to confirm electrical characteristics and pinout configuration. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the part number with the manufacturer's current datasheet to validate availability and any recent design changes before finalizing procurement plans.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for systems needing dynamic power control. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify that the 25.2235 MHz frequency aligns with the system's clocking architecture and jitter specifications.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on standard clock oscillators. The series typically offers various frequencies and voltage options. The 'OE' suffix likely denotes a specific packaging or testing variant within the manufacturer's lineup, distinct from other suffixes like 'PD' or '37.888'.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators with identical 4-SMD no-lead footprints and matching 25.2235 MHz frequency. Verify pin compatibility and tolerance levels when considering alternative manufacturers.
