WebApr 3, 2008 · circuit. Just putting a capacitor in parallel with the crystal will. bring the resonant frequency to the correct value, but won't allow the. oscillator to work. The other question is about the ESR indicated in the crystal datasheet. If this ESR indicated in the datasheet of the crystal is slightly higher. WebSince in the equation for g mcrit the C L term is squared, doubling the load capacitance has the effect of increasing oscillator current by four times. Increasing the crystal ESR by two times causes the required oscillator current to double. Note that this is the minimum estimated oscillator current, which does not include current consumed by additional …
