Crystals Procurement Notes

Verify the specific suffix 'IDR' corresponds to the required tape and reel packaging configuration, as other suffixes may indicate different handling or quantity standards. Confirm that the ±20 ppm stability meets the system timing requirements, noting that this tolerance is standard but less precise than tighter variants like ±10 ppm. Ensure the 18 pF load capacitance matches the oscillator circuit design specifications to maintain accurate frequency operation.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is required for surface-mount designs with moderate stability needs. The 18 pF load capacitance is suitable for many standard microcontroller and FPGA clock inputs. Consider the 100 Ohm ESR value to ensure it falls within the drive level limits of the host oscillator circuit. This model is appropriate for general-purpose timing where extreme precision is not critical.

Crystals Part Context

This part belongs to the CTS Model 402 series, which offers sub-miniature surface-mount crystals. The series covers a frequency range of 16 MHz to 96 MHz and typically provides ±30 ppm standard stability, though this specific variant offers ±20 ppm. The 402 series is characterized by its small physical dimensions and robust construction, making it a common choice for space-constrained electronic devices.

Crystals Replacement Considerations

Direct substitutes include the 402F20022ILR and 402F20022IDT, which share identical electrical parameters and package dimensions. Verify that any replacement maintains the same 18 pF load capacitance and 100 Ohm ESR to ensure circuit compatibility without redesign.
