Electrostatic Discharge (ESD) Precautions

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.

Latch-Up Avoidance

devices are immune to latch-up.

Moisture Sensitivity Level

The Moisture Sensitivity Level rating for the 32-

lead 5x5 mm QFN package is MSL3.

Table 4. Absolute Maximum Ratings

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.

Switching Frequency

The PE42821 has a maximum 25 kHz switching

rate in normal mode (pin 16 = GND). A faster

switching rate is available in bypass mode (pin 16

switched is then limited to the switching time as

specified in Table 1.

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

target value.

Spurious Performance

The typical low-frequency spurious performance

of the PE42821 in normal mode is -137 dBm (pin

16 = GND). If spur-free performance is desired,

the internal negative voltage generator can be

(pin 16).

For applications that require a faster switching rate

or spur-free performance, this part can be

operated in bypass mode. Bypass mode requires

an external negative voltage in addition to an

As specified in Table 3, the external negative

disable and bypass the internal negative voltage

generator.

Hot Switching Capability

The typical hot switching capability of the

PE42821 is +30 dBm. Hot switching occurs when

RF power is applied while switching between RF

ports.
