Crystals Procurement Notes

Verify the specific suffix 'CLR' against the manufacturer's current production status, as availability may vary. Confirm that the 12pF load capacitance matches the target oscillator circuit requirements. Ensure the ±30ppm stability meets the system timing accuracy specifications before integration into the final design.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental crystal with ±30ppm stability is required. The 100 Ohm ESR must be compatible with the driving circuit's oscillation conditions. Consider the 2.0mm x 1.6mm footprint constraints during PCB layout. Verify that the -20°C to +70°C operating range covers the intended application environment.

Crystals Part Context

This part belongs to the CTS Model 402 series, which offers standard surface mount crystals. The series provides various frequency options within a 16MHz to higher range using a consistent 2.0mm x 1.6mm package. The 402 series is designed for general-purpose timing applications requiring reliable fundamental mode performance.

Crystals Replacement Considerations
