PE3501  
Product Specification  
It is the responsibility of the customer to determine  
proper supply decoupling for their design application.  
Evaluation Kit  
Evaluation Kit Operation  
The DEC pin (3) must be connected to a low  
impedance AC ground for proper device operation. On  
the board, two decoupling capacitors (C6 = 10 nF,  
C4 = 10 pF), located on the back of the board, perform  
this function.  
The TSSOP Prescaler Evaluation Board was designed  
to help customers evaluate the PE3501 Divide-by-2  
Prescaler. On this board, the device input (pin 2) is  
connected to connector J1 through a 50 transmission  
line. A series capacitor (C1) 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 15 pF was found  
to be optimal for this board layout; other applications  
may require a different value.  
Applications Support  
If you have a problem with your evaluation kit or if  
you have applications questions, please contact  
applications support:  
The device output (pin 7) is connected to connector J3  
through a 50 transmission line. A series capacitor  
(C2) provides the necessary DC block for the device  
output. Note that this capacitor must be chosen to  
have a low impedance at the desired output frequency  
the device. The value of 47 pF was chosen to provide  
a wide operating range for the evaluation board.

Figure 10. Evaluation Board Layouts  
Peregrine Specification 101/0035  
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 εr 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.
