Absolute Maximum Ratings are those values
listed in the above table. Exceeding these values
may cause permanent device damage.
Functional operation should be restricted to the
limits in the DC Electrical Specifications table.
Exposure to absolute maximum ratings for
extended periods may affect device reliability.

Product Specification
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 PE9301 takes an input signal frequency from
between 1.5 GHz to 3.5 GHz and produces an
output signal frequency half that of the supplied
input. In order for the prescaler to work properly,
several conditions need to be adhered to. It is
crucial that pin 3 be supplied with a bypass
capacitor to ground. In addition, the input and
output signals (pins 2 & 7, respectively) need to
be AC coupled via an external capacitor as shown
in Figure 5.
The ground pattern on the board should be made
as wide as possible to minimize ground
impedance.
