The PE42520 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 13 = GND). The rate at which the
PE42520 can be switched is only limited to the
switching time (Table 1) if an external negative
supply is provided (pin 13 = VSS_EXT).
Switching frequency describes the time duration
between switching events. 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
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 3. When the VSS_EXT control pin is grounded,
FETs in the switch are biased with an internal
negative voltage generator. For applications that
require the lowest possible spur performance,
VSS_EXT can be applied externally to bypass the
Spurious Performance
Notes: 1. 100% duty cycle, all bands, 50Ω.
2. Pulsed, 5% duty cycle of 4620 µs period, 50Ω.
3. Human Body Model (MIL-STD 883 Method 3015).
4. Machine Model (JEDEC JESD22-A115).
5. Charged Device Model (JEDEC JESD22-C101).
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 rating specified.
The typical spurious performance of the PE42520
is –152 dBm when VSS_EXT = 0V (pin 13 = GND). If
further improvement is desired, the internal
negative voltage generator can be disabled by
setting VSS_EXT = –3.4V.

Unlike conventional CMOS devices, UltraCMOS
devices are immune to latch-up.
The Logic Select feature is used to determine the
definition for the CTRL pin.

Thermal Data
Psi-JT (JT), junction top-of-package, is a
thermal metric to estimate junction temperature
of a device on the customer application PCB
(JEDEC JESD51-2).
JT = (TJ – TT)/P
where
JT = junction-to-top of package characterization
parameter, °C/W
TJ = die junction temperature, °C
TT = package temperature (top surface, in the
center), °C
P = power dissipated by device, Watts

Evaluation Kit
Figure 30. Evaluation Kit Layout
The SPDT switch evaluation board was designed
to ease customer evaluation of pSemi’s
PE42520. The RF common port is connected
through a 50Ω transmission line via the SMA
connector, J1. RF1 and RF2 ports are connected
through 50Ω transmission lines via SMA
connectors J2 and J3, respectively. A 50Ω
through transmission line is available via SMA
connectors J5 and J6, which can be used to
de-embed the loss of the PCB. J4 provides DC
and digital inputs to the device.
For the true performance of the PE42520 to be
realized, the PCB should be designed in such a
way that RF transmission lines and sensitive DC
I/O traces are heavily isolated from one another.
