Crystals Procurement Notes

Verify the specific suffix 'I' against official CTS documentation to confirm industrial temperature rating and material composition. Ensure the target PCB footprint matches the 4-SMD no-lead outline dimensions precisely. Cross-reference the 13 pF load capacitance requirement with the host oscillator circuit design to maintain frequency accuracy. Confirm compliance with current environmental directives before final integration.

Crystals Selection Notes

Select this component when a standard 14.7456 MHz reference is required for data transmission protocols. Evaluate the 50 Ohm ESR against the oscillator amplifier's drive level constraints to prevent over-driving. Consider the 13 pF load capacitance compatibility with the system's stray capacitance. Assess the physical profile against available vertical clearance on the printed circuit board.

Crystals Part Context

This component belongs to the CTS 405 Series, which encompasses a range of surface-mount quartz crystals. The series is characterized by ceramic packaging and standardized footprints to facilitate consistent design-in across various electronic products.
