Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required frequency tolerance and temperature range specifications. Confirm that the 1.8V supply voltage aligns with the target system's power architecture. Check package marking codes against official datasheets to authenticate genuine Mercury Electronics components before integration into production lines.

Oscillators Selection Notes

Choose this model when a 2.8224 MHz frequency is strictly required for data rate compatibility. Ensure the design supports 1.8V logic levels and can accommodate the 4-SMD footprint. Consider thermal performance requirements if operating within extended industrial temperature ranges beyond standard commercial limits.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6mm form factor. The series targets high-volume consumer and industrial electronics where size constraints and power efficiency are critical design parameters for timing solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 2.8224 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics before cross-referencing with other manufacturers' equivalent timing devices.
