The PE9313 is a high-performance static UltraCMOSTM
prescaler with a fixed divide ratio of 8. Its operating frequency
range is DC to 1500 MHz. The PE9313 operates on a nominal
3 V supply and draws only 6.5 mA. It is packaged in a small 8-
lead ceramic SOIC and is ideal for frequency scaling and clock
generation solutions.
The PE9313 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.

Device Functional Considerations
The PE9313 divides an input signal, up to a
frequency of 1500 MHz, by a factor of eight
thereby producing an output frequency at an
eighth of the input frequency. To work properly at
higher frequency, the input and output signals
(pins 2 & 7) must be AC coupled via an external
capacitor, as shown in the test circuit in Figure 8.
The input may be DC coupled for low frequency
operation with care taken to remain within the
specified DC input range for the device.
The ground pattern on the board should be made
as wide as possible to minimize ground
impedance. See Figure 7 for a layout example.

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 3.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOSTM
devices are immune to latch-up.
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.

Evaluation Kit Operation
The Ceramic SOIC Prescaler Evaluation Board was
designed to help customers evaluate the PE9313
divide-by-8 prescaler. On this board, the device
input (pin 2) is connected to the SMA connector J1
through a 50
transmission line. A series capacitor
(C3) provides the necessary DC block for the device
input. A value of 1000 pF was used for the
evaluation board; other applications may require a
different value. It is also possible to place a 0
resistor in this location for very low frequency
applications.
The device output (pin 7) is connected to SMA
connector J3 through a 50
transmission line. A
series capacitor (C1) 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
1000 pF was chosen for the evaluation board.
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 0.0061", dielectric
thickness of 0.028", metal thickness of 0.0014", and
r
of 4.6. Note that the predominate mode of these
transmission lines is coplanar waveguide.
J2 provides DC power to the device via pin 1. Two
decoupling capacitors (C2=100 pF, C10=1000 pF)
are included on this trace. It is the responsibility of
the customer to determine proper supply decoupling
for their design application.
