Crystals Procurement Notes

Verify the specific package dimensions and pin configuration against your PCB footprint before ordering. Confirm that the 15pF load capacitance matches your circuit design requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your application's environmental constraints. Check for any specific handling or storage requirements mentioned in the official datasheet.

Crystals Selection Notes

Select this component when a stable 16.9344 MHz reference is required for fundamental mode applications. Consider the ±20ppm stability for systems sensitive to frequency drift. The 30 Ohm ESR should be compatible with your oscillator circuit's drive level limitations. Evaluate the -40°C to +85°C range against your operational environment needs.

Crystals Part Context

This part belongs to the family of surface mount crystals manufactured by HKC. It serves as a passive frequency control device, providing a precise resonant frequency for digital and analog circuits. Unlike active oscillators, it requires an external circuit to generate a clock signal, offering flexibility in system design while maintaining cost-effectiveness.

Crystals Replacement Considerations

Direct substitutes must match the 16.9344 MHz frequency, 15pF load capacitance, and fundamental mode operation. Verify compatibility with existing PCB layouts and mounting types. Ensure replacement parts meet the same ±20ppm stability and -40°C to +85°C temperature specifications.
