Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required tolerance and temperature range specifications. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Cross-reference the part number with official CTS documentation to validate availability status and confirm that no obsolete designations apply before finalizing procurement orders.

Crystals Selection Notes

Select this component when a fixed 27 MHz output is required with moderate stability needs. Ensure the application circuit supports the specified 18 pF load capacitance to maintain accuracy within the ±30 ppm limit. Consider the 60 Ohm series resistance impact on drive level and power consumption. Evaluate thermal performance if operating in high-temperature environments beyond standard commercial ranges.
