Crystals Procurement Notes

Verify the specific ordering suffix and tape/reel packaging configuration directly with the manufacturer or authorized distributors before procurement. Ensure that the requested component matches the exact frequency tolerance and load capacitance requirements of your circuit design. Confirm availability of the 3215 package variant and check for any recent manufacturing updates or lead time variations associated with this specific part number.

Crystals Selection Notes

Select this component when a low-profile, cost-effective crystal oscillator is required for 27MHz timing applications. Consider the 3215 footprint constraints and ensure compatibility with automated pick-and-place assembly processes. Evaluate the ±50ppm tolerance against system jitter requirements and verify that the 18pF load capacitance aligns with the oscillator circuit's external capacitor values to achieve accurate frequency output.

Crystals Part Context

This model belongs to TXC Corporation's line of surface-mount crystal oscillators designed for general-purpose timing needs. The AZ series typically features standardized pinouts and electrical characteristics compatible with common oscillator ICs. The 27.000MHz frequency is commonly used in RF modulation schemes and legacy communication standards, making this component relevant for mixed-signal designs requiring stable clock sources.

Crystals Replacement Considerations

Direct substitutes must match the 27.000MHz frequency, 3215 package dimensions, and CMOS output type. Verify equivalent load capacitance and temperature range specifications from alternative manufacturers. Cross-reference pin assignments and drive level settings to ensure functional compatibility without circuit modification.
