R2 optimum value depends on the frequency and required stability against changes in VCC or average minimum ICC (ICC is typically 5 mA at VCC = 5 V and f = 10 MHz). RS ≈ 2 × R. The average ICC (mA) is approximately 3.5 + 0.05 × f (MHz) × C (pF) at VCC = 5.0 V (for more information refer to “DESIGNERS GUIDE”). Fig.
