Absolute Maximum Ratings are those values
listed in the above table. Exceeding these values
may cause permanent device damage. Exposure
to absolute maximum ratings for extended periods
may affect device reliability.

Advance Information
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 in Table 3.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Device Functional Considerations
The PE9308 takes an input signal frequency from
between 4.0 GHz to 13.5 GHz and produces an
output signal frequency one-fourth that of the
supplied input. In order for the prescaler to work
properly, several conditions need to be adhered
to. It is crucial that pins 1, 2 and 5 be supplied
with a bypass capacitor to ground. In addition, the
output signal (pins 6) needs to be ac coupled via
an external capacitor as shown in the test circuit
below.
The ground pattern on the board should be made
as wide as possible to minimize ground
impedance.
