Notes. The SM5009 series reduce crystal current by limiting driving current of oscillating-stage inverter and inhibiting oscillating amplitude. Depending on
the characteristics of using crystal or the mounting condition, they may not oscillate normally. Please evaluate the oscillation start-up characteris-
tics adequately with your actual device.
