The PE43704 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 20 = GND). The rate at which the
PE43704 can be switched is only limited to the
switching time (Tables
1-3)
if an external negative
supply is provided (pin 20 = Vss
EXT
).
Switching frequency is defined to be the speed at
which the DSA can be toggled across attenuation
states. Switching time is the time duration
between the point the control signal reaches 50%
of the final value and the point the output signal
reaches within 10% or 90% of its target value.
Optional External Vss Control (Vss
EXT
)
For proper operation, the Vss
EXT
control pin must
be grounded or tied to the Vss voltage specified in
Table 5.
When the Vss
EXT
control pin is grounded,
FETs in the switch are biased with an internal
voltage generator. For applications that require
the lowest possible spur performance, Vss
EXT
can
be applied externally to bypass the internal
negative voltage generator.

Exceeding absolute maximum ratings may cause
permanent damage. Operation should be
restricted to the limits in the Operating Ranges
table. Operation between operating range
maximum and absolute maximum for extended
periods may reduce reliability.
Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS
®
device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the specified rating.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS
®
devices are immune to latch-up.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the
PE43704 in the 5x5 QFN package is MSL1.
Safe Attenuation State Transitions
The PE43704 features a novel architecture to
provide safe transition behavior when changing
attenuation states. When RF input power is
applied, positive output power spikes are
prevented during attenuation state changes by
optimized internal timing control.
