** These parameters are design targets and are not tested. No characterization data available at this time.
Note 1: Data in the Typical (“Typ ”) column is at V
REG = 5V, VDD = 9V, 25°C unless otherwise stated. These parame-
ters are for design guidance only and are not tested.
2: Measurements are taken in RC Mode where CLKOUT output is 8 x TOSC.
3: See Figure 10-1 for loading conditions.
