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 15pF)
Power supply decoupling pin. Place a
capacitor as close as possible and connect
directly to the ground plane (eg 10 nF and
10 pF).
Ground pin. Ground pattern on the board
should be as wide as possible to reduce
ground impedance.
Ground pin.
Ground pin.
Divided frequency output pin. This pin
should be coupled with a capacitor (eg 100
pF).
Ground pin.
Device Functional Considerations
The
PE83503
takes an input signal frequency from
1.5 GHz to 3.5 GHz and produces an output signal
frequency one-eighth 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 the test
circuit in Figure 7.
The ground pattern on the board should be made
as wide as possible to minimize ground
impedance.
