Crystals Procurement Notes

Verify the specific suffix designation against official Meritek documentation to confirm exact electrical tolerances and temperature ranges. Ensure the ordering code matches the required load capacitance and frequency stability specifications for the target application. Confirm RoHS compliance status as indicated in the final datasheet revision. Cross-reference the manufacturer part number with distributor listings to validate current availability and authenticity before procurement.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is required for surface mount designs. The 16 pF load capacitance must match the oscillator circuit requirements. Consider the ±30 ppm tolerance for precise timing needs. Evaluate the -40°C to +85°C range against environmental conditions. Compare ESR limits with driver strength capabilities to ensure stable oscillation without overdriving the crystal element.

Crystals Part Context

This part belongs to the MXJ series of ceramic SMD crystals from Meritek. The series offers various frequencies and package sizes for different mounting constraints. The MXJ line focuses on providing stable frequency references for digital logic and communication interfaces. It serves as a passive timing element essential for clock generation in modern electronics.

Crystals Replacement Considerations

MXJDHJI40M0 shares similar packaging but operates at 40 MHz. MX6EAJB20M0 is a 6.0x3.5mm variant with different electrical parameters. Verify pin compatibility and mechanical footprint before substitution.
