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.

Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOS™

devices are immune to latch-up.

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.

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.

Pin No.

Name

Description

VDD

Power supply pin. Bypassing is required.

Input signal pin. Should be coupled with a

capacitor (eg 15 pF).

DEC

Power supply decoupling pin. Place a

capacitor as close as possible and connect

directly to the ground plane.

GND

Ground pin. Ground pattern on the board

should be as wide as possible to reduce

ground impedance.

GND

Ground pin.

No connection. This pin should be left

open.

OUT

Divided frequency output pin. This pin

should be coupled with a capacitor

(eg 47 pF).

GND

Ground Pin.
