Crystals Procurement Notes

Verify the specific suffix J against official CTS documentation to confirm pinout and electrical characteristics match design requirements. Ensure the selected variant aligns with the required load capacitance and ESR specifications for the target oscillator circuit. Cross-reference the RoHS compliance status with current regulatory standards for the destination market. Confirm that the operating temperature range meets the environmental conditions of the final application.

Crystals Selection Notes

Select this component when a 14.4 MHz fundamental frequency with tight ±10ppm stability is required. Consider the 10pF load capacitance requirement to ensure proper oscillation amplitude and frequency accuracy. Evaluate the 60 Ohm ESR against the oscillator driver strength to prevent overdriving or startup failures. Verify that the 4-SMD footprint fits within the available PCB area and that the height constraints are satisfied.
