Procurement Notes

Verify the specific suffix '022' against official Renesas documentation to confirm pinout, electrical characteristics, and packaging details. Ensure compatibility with existing board layouts and power supply specifications before procurement. Check for any recent Product Change Notifications (PCNs) that may affect material composition or assembly sites.

Selection Notes

Select this component when low jitter performance is critical for system stability. Compare output drive strength and voltage levels against load requirements. Consider the available input frequency range and the need for frequency multiplication or division. Evaluate thermal management needs based on the operating environment and power dissipation characteristics of the VFQFPN package.
