Crystals Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration when placing orders. Confirm that the required frequency tolerance and load capacitance match the target circuit design specifications. Ensure compatibility with the designated supply voltage range during integration. Cross-reference the pinout diagram with the PCB layout to prevent installation errors. Validate that the operating temperature range meets the environmental requirements of the final application.

Crystals Selection Notes

Select this component when a 14.7456 MHz clock source is required for systems utilizing 1.8V or 3.3V logic levels. Consider the 3225 package size for space-constrained designs where surface mount technology is preferred. Evaluate the ±50 ppm stability requirement against system timing constraints. Assess power consumption needs relative to other oscillator types available in the same footprint. Verify that the CMOS output drive capability matches the input requirements of the downstream components.

Crystals Part Context
