, the clock must be AC coupled.
(8) Parameter is specified by design, not tested in production.
(9) Specified by characterization.
(10) The ESR requirements stated are what is necessary in order to ensure that the Oscillator circuitry has no start up issues. However,
lower ESR values for the crystal might be necessary in order to stay below the maximum power dissipation requirements for that crystal.
