Note 1: Absolute maximum ratings are those values beyond which the life
of a device may be impaired.
Note 2: DC offset is measured with respect to Pin 3.
Note 3: There are several operating modes which reduce the supply
current. For V
reduced by 50% relative to V
clock source and the divide-by-4 or divide-by-16 mode is enabled, the
supply current is typically reduced by 60%,relative to divide-by-1 mode,
independent of the value of V

LOAD
Note 4: The maximum clock frequency is arbitrarily defined as the
frequency at which the filter AC response exhibits >1dB of gain peaking.
Note 5: The minimum clock frequency is arbitrarily defined as the frequecy
at which the filter DC offset changes by more than 5mV.
Note 6: Thermal resistance varies depending upon the amount of PC board
metal attached to the device.
