Notes:
1 _{Contact the factory for operational capabilities beyond 250MHz.}
2 _{Simulation results (not measurements).}
3 _{Code=0 corresponds to “00000000000” as seen in the shift register (no additional capacitance).}
4 _{Code=1023 corresponds to “11111111110” as seen in the shift register (maximum additional capacitance). CHK = 0.}
5 _{The CHK bit is not used to determine the Code’s decimal value.}
6 _{Capacitance variations due to temperature are always smaller than 180fF between the nominal temperature (25°C) and maximum or minimum}
operating temperature.
