• Utilizes KX-9B quartz precision technology for signal conditioning
• Supports integration with ASIC, MCU, MPU, or FPGA architectures

Crystals Applications

• Clocking tree signal conditioning for microcontrollers
• Frequency reference for field-programmable gate arrays
• Signal processing circuits in application-specific integrated systems

Crystals Procurement Notes

Verify the specific manufacturing lot and date code upon receipt to ensure compliance with Class III life supporting device standards. Confirm that the received components match the 4-SMD No Lead package specification. Check for any distributor-specific handling requirements due to potential supply chain delays associated with high order volumes. Ensure storage conditions maintain component integrity prior to soldering.

Crystals Selection Notes

Select this component when a 27.12 MHz reference is required for digital logic interfaces. The 12pF load capacitance must align with the oscillator circuit design specifications. Consider the 50 Ohm ESR for impedance matching within the host system. The SMD form factor is appropriate for high-density PCB layouts where through-hole alternatives are unsuitable.
