Notes:
1) Normal mode: connect VSS_EXT (pin 29) to GND (VSS_EXT = 0V) to enable internal negative voltage generator.
2) Bypass mode: use VSS_EXT (pin 29) to bypass and disable internal negative voltage generator.
3) The input 0.1dB compression point is a linearity figure of merit. Refer to Table 2 for the RF input power (50Ω).

Switching Frequency
The PE42553 has a maximum 25 kHz switching rate
in normal mode (pin 13 tied to ground). A faster
switching rate is available in bypass mode (pin 13 tied
to VSS_EXT). The rate at which the PE42553 can be
switched is then limited to the switching time as
specified in Table 3.
Switching frequency describes the time duration
between switching events. Switching time is the time
duration between the point the control signal reached
50% of the final value and the point the output signal
reaches within 10% or 90% of its target value.
Spur-Free Performance
The typical spurious performance of the PE42553 in
normal mode is –152 dBm (pin 13 tied to ground). If
spur-free performance is desired, the internal
negative voltage generator can be disabled by
applying a negative voltage to VSS_EXT (pin 13).
Logic Select
The Logic Select feature is used to determine the
definition for the CTRL pin.
Control Logic
Table 4 provides the control logic truth table for the
PE42553.
