In most cases, the RD is 0 ⦠and RF is inï¬nite. It is determined and speci-
ï¬ed by the crystal/ceramic resonator manufacturer. The RD can be
increased to decrease the amount of drive from the oscillator output to the
crystal. It can also be used as an adjustment to avoid clipping of the oscil-
lator signal to reduce noise. The RF can be used to improve the start-up of
the crystal/ceramic resonator. The Z8® oscillator already has an internal
shunt resistor in parallel to the crystal/ceramic resonator.
