Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official Crystal Part Numbering Guide to ensure correct electrical parameters and packaging configuration. Confirm that the requested variant matches the required load capacitance and frequency tolerance specifications for the target circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is required in a compact SMD footprint. Ensure the host circuit supports an 8 pF load capacitance to maintain the specified ±25 ppm frequency tolerance. Verify that the 60 Ohm ESR aligns with the oscillator circuit's drive level requirements to prevent over-driving or failure to start.

Crystals Part Context

This part belongs to the ECX-2236 series of crystals designed for high-frequency stability in small packages. It serves as a passive timing element within larger electronic systems, providing the necessary clock reference for microcontrollers and RF transceivers. The component is distinct from oscillators as it requires an external active circuit to generate a square wave output.

Crystals Replacement Considerations

No public substitute part numbers are documented in the provided source material. Cross-referencing with other manufacturers requires independent verification of pinout compatibility, electrical parameters, and mechanical dimensions.
