ADVANCE INFORMATION
PE9301
Product Description
The PE9301 is a high performance monolithic CMOS
prescaler with a fixed divide ratio of 2. Its operating
frequency range is 1.5 GHz to 3.5 GHz. The PE9301
operates on a nominal 3 V supply and draws only 13 mA.
It is packaged in a small 8-lead SOIC and is ideal for
Space microwave PLL synthesis solutions.
The PE9301 is manufactured in Peregrine’s patented
Ultra Thin Silicon (UTSi®) CMOS process, offering the
performance of GaAs with the economy and integration
of conventional CMOS.

Electrostatic Discharge (ESD) Precautions
When handling this UTSi 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, UTSi CMOS
devices are immune to latch-up.

Description
Power supply pin. Bypassing is required.
Input signal pin. Should be coupled with
a capacitor (eg 15 pF).
Power supply decoupling pin. Place a
capacitor as close as possible and
connect directly to the ground plane.
Ground pin. Ground pattern on the board
should be as wide as possible to reduce
ground impedance.
Ground pin.
No connection. This pin should be left
open.
Divided frequency output pin. This pin
should be coupled with a capacitor
(eg 47 pF).
Ground Pin.
Device Functional Considerations
The PE9301 takes an input signal frequency from
between 1.5 GHz to3.5 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.
