Crystals Procurement Notes

Verify the specific suffix 'CDT' corresponds to the required tape and reel packaging configuration. Confirm that the 18pF load capacitance matches the oscillator circuit design requirements. Ensure the ±30ppm stability meets the system timing accuracy specifications. Check current availability status as components may be subject to discontinuation or supply constraints.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental frequency is required for digital systems. The 18pF load capacitance must align with the host oscillator's internal capacitance settings. Consider the 4-SMD package size for PCB space constraints. Evaluate the ±30ppm tolerance against the application's jitter and drift requirements.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequency codes and load capacitances.
