Spurious Performance
The typical spurious performance of the PE42551
is -116 dBm when V_SS = 0V. If further improvement
is desired, the internal negative voltage generator
can be disabled by externally applying a negative
voltage to the V_SS pin such that V_SS = -V_DD.

Logic Select (LS)
The Logic Select feature is used to determine the
definition for the CTRL pin.
Switching Frequency
The PE42551 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used. In the event a customer applies V_SS
external (-V_DD) to Pin 18, the Switching Rate is
limited to the reciprocal of the Switching Time in
Table 1.
