Evaluation Kit Contents & Requirements

The Evaluation Kit includes all of the specific software and hardware required to evaluate

the PE3336. Included in the Evaluation Kit are:

1 PE3336 Evaluation Board

1 PE3336 3 GHz Integer-N PLL

1 Peregrine CD-ROM with application software included

2 Jumpers

1 4-Wire Interface Cable with GND

3 Power Supply Cables

1 Set of Evaluation Kit Data Plots

In order to program the part using serial programming mode the Evaluation Kit software

will need to be installed on a computer with the following minimum requirements:

PC Compatible with Windows™ ’95/98/2000

Mouse

Parallel Port

HTML Browser to access CD contents

CAUTION: The PE3336-EK circuit contains components that might be damaged by

exposure to voltages in excess of the specified voltage, including voltages produced by

electrostatic discharges. Handle the board in accordance with procedures for handling

static-sensitive components. Avoid applying excessive voltages to the power supply

terminals or signal inputs or outputs.

Peregrine Semiconductor Corportation 8 Doc. 79/0056~00A

Evaluation Kit Configuration

The PE3336 Evaluation Board is configured with an on-board VCO, TCXO reference and

a second order active loop filter. The loop filter is followed by a low pass filter after the

Op Amp. The VCO tuning range is 3000 MHz to 3500 MHz and the reference oscillator

runs at 10 MHz. The active loop filter is designed for a 1 MHz comparison frequency and

a 3000 MHz output frequency with unity gain crossover at 75 kHz, phase margin of 65

degrees and 1.2 dB of peaking. The data provided was measured in this configuration

with the default jumper settings shown in Figure 2.

Two jumpers (JP1 & J3) configure the Evaluation Board to operate with either the on-

board reference oscillator (TCXO) or an external reference applied to J10. Figure 2

shows the proper configuration for utilizing the TCXO reference. JP1 in the middle-to-

right connection as shown connects the output of the TCXO to the PLL FR input, while J3

installed provides power to the TCXO. Do not connect any external reference to J10 if

the on-board reference is selected. Figure 3 displays the proper configuration for

utilizing an external reference source. JP1 is in the middle-to-left connection, which

connects the PLL FR input to the J10 SMA connector and the jumper on J3 is removed to

power-down the TCXO.

The PE3336 Evaluation Kit also allows for manual programming using the fifteen on-

board switches. Setting the BMODE Control switch ON (BMODE switch S3-1) enables

direct mode programming. Setting the BMODE Control switch to the OFF position (S3-1)

and the A3-S_mode switch to the ON position (S3-8) the serial programming mode is

enabled allowing for software control.

The default jumper and switch settings are shown in Figure 2, which will place the part

into serial programming mode utilizing the on-board reference. Peregrine Semiconductor

recommends that the default settings be used initially to bring up the evaluation board

and duplicate the enclosed measured data.

Evaluation Kit Setup

1. Verify a jumper is placed on the connector J3 and REF Selector (JP1) is positioned

to select the on-board reference as shown in Figure 2.

2. Connect power supply cables to the Evaluation Kit board as shown in Figure 1.

Verify all supplies are turned off prior to connecting to evaluation board.

! Connect the +3 V supply to VccPLL (J7 Pins 1 & 3)

! Connect the +5 V supply to VccVCO (J7 Pins 31 & 33)

! Connect the ±6 V supply to VccOpAmp

J7-13: +6 V Red Connector

J7-15 & J7-17: GND Green Connector

J7-19: -6 V Black Connector

3. Using the application software provided and described in detail in the next section,

serial and direct programming can be evaluated. To enable software control of the

evaluation board, ensure all DIP switches are turned OFF except for ENH (S1-1) and

A3-S_Mode (S3-8) as shown in Figure 2. The 4-wire interface cable (3-wire serial

interface and GND) should be connected from your computer’s printer port to J1 on

the evaluation board to enable software control.

4. Direct mode programming can be evaluated manually without the Application

Software enabled. To enable direct mode programming, both the ENH (S1-1) and

the Bmode (S3-1) DIP switches should be turned on. The on-board DIPswitches

can then be used to manually program the PLL. Note that M7 register is not

available in the direct mode programming. Instructions for programming PLL

registers are available in the datasheet.

5. The output of the on-board VCO can be measured by connecting a spectrum

analyzer to port J5. Additional GND posts and test points are available on the

Evaluation Board for measurement flexibility.

6. Refer to the next section for further information on configuring and running the

application software.

Peregrine Semiconductor Corportation 14 Doc. 79/0056~00A

Software Installation Instructions

In order to setup the Evaluation Software on your computer:

1. Start Microsoft Windows™ ’95/98/2000.

2. Insert the Peregrine CD into CDROM drive. If your computer has AutoPlay enabled

and the splash screen automatically appears, select the Products link at the bottom of

the splash screen. If the Peregrine splash screen does not automatically appear,

utilize Windows Explorer to browse the CD directory and open the file \cd\startup.htm.

3. Select the PE3336 link on the Products page to obtain product information and

evaluation kit documentation.

4. Select the Evaluation Board Software link and choose the option of “Run this program

from its current location.” Identify the desired directory for installation and select the

Unzip option when the WinZip Self-Extractor window appears.

5. Utilize Explorer to run Setup.exe from your hard disk directory and follow the

instructions on the screen. This will install the Evaluation Kit Application Software in

the selected directory and add a shortcut to the Windows Start menu.

Printer Port Programming

When programming the PE3336 in serial mode using the computer printer port option,

the following software programming features are not available:

! Enhancement modes

! Parallel and Direct interface modes

! Ping-pong mode

Ping-pong mode may be implemented on the evaluation setup by attaching a square-

wave generator to J1-5 pin of the Serial Control connector and programming both

primary and secondary registers.

Software Operation Instructions

To run the PE3336 using your computer’s parallel port follow steps 1 through 7 below

and reference Figure 4.

Step 1: Start the Peregrine Integer-N PLL EK Control program. This is a generic

program for all Interger-N PLL’s at Peregrine Semiconductor.

Peregrine Semiconductor Corportation 15 Doc. 79/0056~00A

Step 2: Select the PE3336 from the pull-down menu button in the upper left corner of

the program screen. This selection will enable certain product specific modes

of operation.

Step 3: If the on-board reference is being used, set the reference frequency to 10 MHz

by typing 10 into the reference frequency box. If an external reference is

applied, type in the appropriate reference value in MHz.

Step 4: Set reference counter (R counter) to 9 by entering it into the R counter box in

the "R M A Select" box in the bottom left corner. Note that the numbers in the

orange boxes are computed values and cannot be directly typed in.

Step 5: Verify frequency step = 1.000 MHz.

Step 6: Set Frequency to 3000 MHz by typing it into the secondary register frequency

box. Once the frequency values are entered by "Enter" key in the keyboard,

the software will automatically send out data to program PLL. You can also

click the "Send Data" button to program PLL.

Step 7: Verify on the spectrum analyzer that the part locks at 3000 MHz.

Programming Tip

When the PLL is first powered on and before programming, the Op Amp output could be

resting at a negative voltage preventing proper VCO operation. The PLL will not lock in

this condition. If this mode occurs, the power supply for Op Amp (± 6V) should be

cycled. To prevent this from happening, the following power on sequence is

recommended:

1. Turn on power supplies for PLL VDD and VCO VCC.

2. Program PLL.

3. Turn on the power supply for the Op Amp.
