DC - 1500MHz Low Power
CMOS Divide-by-2 Prescaler
Features
DC to 1500 MHz operation
Fixed divide ratio of 2
Low-power operation: 14mA
typical @ 3.0 V
Ultra small package: 8-lead
plastic MSOP
The PE83511 is a high-performance static CMOS
prescaler with a fixed divide ratio of 2. Its operating
frequency range is DC to 1500 MHz. The PE83511
operates on a nominal 3V supply and draws only 14mA.
It is packaged in a small 8-lead plastic MSOP and is
ideal for frequency scaling and clock generation
solutions.
The PE83511 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.
Device Functional Considerations
The PE83511 divides an input signal, up to a
frequency of 1500 MHz, by a factor of two thereby
producing an output frequency at half the input
frequency. To work properly at higher frequency,
the input and output signals (pins 2 , 7 & optional
5) must be AC coupled via an external capacitor.
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.
OUTB Control
Pin 6 controls weather OUTB is enabled or
disabled. Pin 6 has an internal pull-up resistor.
With no connection (floating), OUTB is disabled.
By grounding pin 6, OUTB is enabled. By
enabling OUTB, this part will consume roughly 5
mA more current.

Figure 7. Evaluation Board Schematic Diagram
Figure 8. Evaluation Board Layout
Evaluation Kit Operation
The PE83511 EK board was designed to ease
customer evaluation of Peregrine's high
performance divide-by-2 Military Grade Prescaler.
On this board, the device input (pin 2) is connected
via connector J1 and a 50 transmission line. A
series capacitor (C3) provides the necessary DC
block for the device input. It is important to note
that the value of this capacitance will impact the
performance of the device. A value of 1000 pF was
found to be optimal for this board layout; other
applications may require a different value.
The device output (pin 7) is connected to connector
J3 through a 50 transmission line. A series
capacitor (C1) provides the necessary DC block for
the device output. Note that this capacitor must be
chosen to have low impedance at the desired
output frequency the device. The value of 1000 pF
was chosen to provide a wide operating range 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 0.007", dielectric thickness of 0.028", metal
thickness of 0.0014" and
r
of 4.4. Note that the
predominate mode for these transmission lines is
coplanar waveguide.
J2 provides DC power to the device. Starting from
the lower left pin, the second pin to the right (J2-3)
is connected to the device VDD pin (1). Two
decoupling capacitors (10 pF, 1000 pF) are
included on this trace. It is the responsibility of the
customer to determine proper supply decoupling for
their design application.
