Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct output logic levels and tolerance specifications. Confirm that the requested quantity aligns with standard packaging units to avoid partial reel issues. Ensure compatibility with your board's thermal profile during reflow soldering processes. Cross-reference the part number with the latest revision history to confirm component availability and lifecycle status before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12.288 MHz reference is required with ±20ppm stability. The 2.5V supply voltage must match your system's core logic levels. Consider the 5.0mm x 3.2mm package size for space-constrained layouts. Verify that the HCMOS/TTL output swing is compatible with downstream input thresholds. Evaluate the enable pin requirement if dynamic power saving is necessary for the application design.

Crystals Part Context

This oscillator belongs to the 435 series from CTS-Frequency Controls, designed for general-purpose timing applications. It serves as a critical timing element in digital circuits, replacing discrete crystal resonators by integrating the oscillator circuit into a single package. The series offers various frequencies and packages to support diverse embedded system requirements across industrial and consumer markets.

Crystals Replacement Considerations

Direct substitutes include other 12.288 MHz oscillators with identical 2.5V HCMOS outputs and similar ±20ppm stability. Check pinout compatibility for the 2-pad SMD configuration. Ensure replacement parts meet the same -40°C to +85°C operating temperature range. Verify that alternative manufacturers offer equivalent RoHS compliance and lead-free soldering characteristics.
