The PE3513 is a high-performance static

UltraCMOSTM

prescaler with a fixed divide ratio of 8. Its operating frequency
range is DC to 1500 MHz. The PE3513 operates on a nominal
3 V supply and draws only 8 mA. The input and output
interfaces support both AC-coupled, low-Z RF as well as direct
connection to low voltage positive logic devices. It is packaged
in a small 6-lead SC-70 and is ideal for frequency scaling
solutions

The PE3513 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 UltraCMOSTM 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 6.

Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOSTM
devices are immune to latch-up.

Figure 3. Pin Configuration (Top View)

Device Functional Considerations

The PE3513 divides an input signal, up to a
frequency of 1500 MHz, by a factor of eight
thereby producing an output frequency at one-
eighth the input frequency. To work properly with
low impedance, ground referenced interfaces, the
input and output signals (pins 3 & 6) must be AC
coupled via an external capacitor, as shown in the
test circuit in Figure 4.

The ground pattern on the board should be made
as wide as possible to minimize ground
impedance. See Figure 9 for a layout example.

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.

Evaluation Kit Operation

The SC-70 Prescaler Evaluation Board was
designed to help customers evaluate the PE3513
divide-by-8 prescaler. On this board, the device
input (pin 3) is connected to connector J1 through a
50

transmission line. A series capacitor (C1)

provides the necessary DC block for the device
input. A value of 100 pF was used for this board
layout; other applications may require a different
value.

The device output (pin 6) is connected to J3 through
a 50

transmission line. A series capacitor (C5)

provides the necessary DC block for the device
output. This capacitor value must be chosen to have
a low impedance at the desired output frequency of
the device. A value of 100 pF was chosen for the
evaluation board. At both input and output, select a
capacitor value that offers low series reactance while
ensuring that any parasitic resonances are well
above the operating bandwidth.

The board is constructed of a two-layer FR4 material
with a total thickness of 0.031". The bottom layer
provides ground for the RF transmission lines. The
transmission lines were designed using a coplanar
waveguide above ground plane model with trace
width of 0.030", trace gaps of 0.007", dielectric
thickness of 0.028", metal thickness of 0.0014", and

of 4.4. Note that the predominate mode of these

transmission lines is coplanar waveguide. Liberal
numbers of plated through holes unite

the top and

bottom ground areas for best performance.

J6 provides DC power to the device via pin 4. Two
decoupling capacitors (100 pF, 1000 pF) are
included on this trace. It is the customer's
responsibility to determine proper supply decoupling
for their design application.
