Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required tolerance and temperature specifications. Confirm that the 2-SMD package dimensions align with the designated footprint on the printed circuit board. Check for any recent lifecycle status updates or recommended replacement part numbers from CTS-Frequency Controls prior to finalizing procurement orders.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with tight ±20 ppm tolerance. Ensure the application environment remains within the -20°C to +70°C operational range. Verify that the target circuit impedance matches the 10 pF load capacitance specification. Consider the 40 Ohm ESR value for oscillator circuit stability calculations during the design phase.
