Crystals Procurement Notes

Verify the specific suffix 'XX' in the model number against official CTS documentation to confirm exact pinout and electrical characteristics, as generic placeholders may indicate variable configurations. Ensure compatibility with reflow soldering profiles specified in the manufacturer datasheet. Confirm that the 8pF load capacitance matches the target circuit design requirements before integration.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference is required for surface mount PCB layouts. The 5.0mm x 3.2mm footprint offers a compact solution compared to larger HC-49 packages. Consider the ±15ppm tolerance relative to system timing accuracy needs. Verify that the 50 Ohm ESR aligns with the oscillator circuit's drive level specifications to prevent over-driving the crystal.

Crystals Part Context

This component belongs to the CTS Frequency Controls portfolio of precision timing devices. It serves as a passive resonator element within active oscillator circuits or direct clock inputs. The product line emphasizes reliability and stability for consumer and industrial electronics. The specific model represents a standard frequency point widely used in digital systems requiring precise timekeeping or data synchronization.

Crystals Replacement Considerations

Direct substitutes must match the 14.31818 MHz frequency, 8pF load capacitance, and 2-SMD no-lead package dimensions. Verify equivalent ESR values and stability ratings. Cross-reference with other manufacturers offering similar surface mount crystals to ensure mechanical and electrical compatibility.
