Included in the Evaluation Kit are: 1 PE3341 Evaluation Board 1 PE3341 2.7 GHz Integer-N EEPROM PLL 1 Peregrine CD-ROM 4 Jumpers 1 26-Wire PSC Universal LPT1 Interface Cable 2 2-Wire Power Supply Cables 1 4-Wire Power Supply Cable 1 Set of Evaluation Kit Data Plots In order to program the part using EEPROM programming mode the evaluation kit software will need to be installed on a computer with the following minimum requirements: PC Compatible with WindowsTM '95/98/2000 Mouse Parallel Port HTML Browser to access CD contents CAUTION: The PE3341-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 7 Doc. 79/0072~00B Evaluation Kit Configuration The PE3341 Evaluation Board is configured with an on-board VCO, TCXO reference and a second order passive loop filter. For the standard evaluation kit, the VCO tuning range is 2500 MHz to 2670 MHz for a tuning voltage 0.5 to 4.5 volts. However, the maximum charge pump operable voltage range of the PE3341 is 0.5 to 2.5 volts. Its optimum range is 1 to 2 volts which corresponding an optimum operating frequency range 2520 to 2570 MHz. The reference oscillator is 20 MHz. The passive loop filter is designed for a 1 MHz comparison frequency and a 2540 MHz output frequency with unity gain crossover at 45 kHz, phase margin of 65 degrees and 1.2 dB of peaking. Unless noted, the data provided was measured in this configuration with the default jumper settings shown in Figure 1. Two jumpers (J5 & J6) configure the Evaluation Board to operate with either the onboard reference oscillator (TCXO) or an external reference applied to J7. Figure 1 shows the proper configuration for utilizing the on-board TCXO reference. J6 in the middle-to-right connection as shown connects the output of the TCXO to the PLL fr input, while J5 installed provides power to the TCXO. Do not connect any external reference to J7 if the on-board reference is selected. To use an external reference, place J6 in the middle-to-left connection which connects the PLL fr input to the J7 SMA connector and remove the jumper on J5 to power-down the TCXO. Figure 2 shows the configuration of using an external reference. The default jumper and switch settings are shown in Figure 1, which place the part into EEPROM 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 Default Jumper & Switch Settings Using on-board Reference. Evaluation Kit Setup 1. Verify a jumper is placed on the connector J5 and REF Selector (J6) is positioned in the middle-to-right connection to select the on-board reference as shown in Figure 1. 2. Verify that no jumper is placed on the connector J2; Switch 1 of SW1 is at "ON" position and the rest of the switches are at "OFF" position. 3. Verify that the jumper is at center-to-right connection on the connector J8. This is to prevent VPP from being accidentally activated. 4. Connect power supply cable to the Evaluation Kit board as shown in Figure 1. Note that the red connector of the power cable is always the positive and the black connector is ground in a 2-wire cable or the negative in a 4-wire cable. Verify all supplies are turned off prior to connecting to evaluation board. Peregrine Semiconductor Corportation 9 Doc. 79/0072~00B ! Connect the +3 V supply to J3-1 (+) and J3-3 (GND) ! Connect the +5 V supply to J3-17 (+) and J3-19 (GND) The PE3341 EEPROM on the evaluation board has been programmed and tested before stocking. No connection to J1 or J9 is necessary for normal operation. To prevent the EEPROM from being accidentally erased or re-programmed, always place a jumper at center-to-right connection on the connector J8 to prevent VPP from being accidentally activated. 5. Turn on the powers to the board. 6. The output of the on-board VCO can be measured by connecting a spectrum analyzer to port J4. Before making modifications to the board, verify and duplicate the performance found in the included plots. Additional GND posts and test points are available on the Evaluation Board for measurement flexibility. 7. Using the application software provided and described in detail in the next section, EEPROM programming can be evaluated.

Jumper Setting for EEPROM Programming. Reprogramming the EEPROM With the EE Programming kit set up completed as described in the previous section, the follow steps are for programming of the EEPROM register. Step 1: Start the "Peregrine EE PLL Control Software" program. Figure 4 shows one example of the screen. Step 2: .Verify the "EEPROM Register" is displayed in the drop down menu in the middle section. Step 3: Enter reference frequency (crystal frequency) value in MHz into the Ref Freq box (marked by red dot at left) Peregrine Semiconductor Corportation 14 Doc. 79/0072~00B ! Light blue number boxes identify user defined program states and can be modified by utilizing the arrows next to the boxes or clicking into the box and typing the appropriate value. Either clicking on the light blue switches or typing the counter variable into the text box can program the registers. ! Programming of the secondary or EEPROM register is selected by the light blue pull down box. Note: EEPROM register is the default selection. Do not change it. ! The prescaler enabled or disabled can be selected by the light blue Prescaler switch. "Enable" is the default selection. ! The enhancement mode enable function is currently unavailable. ! Data is sent to the evaluation board by clicking the dark blue "SEND DATA" button. Figure 4. Example of EEPROM Programming Software Screen. Peregrine Semiconductor Corportation 15 Doc. 79/0072~00B Step 4: Set reference counter (R counter) to the desired value by entering it into the R Register box in the middle left side (marked by yellow dot at left). Note that the numbers in the orange boxes are computed values and cannot be directly typed in. Step 5: Verify "frequency step" (which is also called phase detector frequency) is at the desired value. Step 6: Verify that the Prescaler switch is in the default position "Enable" for a normal operation. Switch it to "Disable" position if the prescaler is to be bypassed (disabled). Step 7: Set the VCO frequency to the appropriate value by typing it into the "Out Freq (MHz)" box. Once the frequency value is entered into the box, the corresponded M and A register values are displayed in the "M Register" and "A Register" Boxes, respectively. Instead of entering the frequency value into the "Out Freq (MHz)" box, the frequency can also be changed by entering M register and A register values into the "M Register" and "A Register" boxes directly. Step 8: Click the "SEND DATA" button to send data to the PLL. Step 9: The program will automatically read back the R, M and A Register values and display them in the bottom section. If the EEPROM is programmed successfully, a message "Device Programmed Successfully!" with a green dot will display in the bottom section as shown in Fig. 4. Otherwise, if any of the read back values is different from the programmed value, a message "Device Programming Failed!" with a red dot will display as shown in Fig. 5. This feature can be used to read back the R, M and A Register values of a previous programmed part. To do this, just complete the previous section "Evaluation Kit Configuration for EEPROM Programming" and Steps 1 and 2 of this section and then click the "READ DATA" button in the right bottom corner. The "READ DATA" function will read back and display the R, M and A Register values of a previous programmed part without showing other message. Step 10: Once the EEPROM has been programmed, return jumper J8 to the center-toright position. This is to ensure that the EEPROM register data is not corrupted by an inadvertent load. Step 11: Remove jumper J2 to select EEPROM register. Step 12: Move Switch 1 of SW1 to the "On" position. Step 13: Verify on the spectrum analyzer that the part locks to the desired frequency (J1 and J9 can be disconnected from the cables or remained connected for this operation). Step 14: To exit the program, click the "QUIT" button. Peregrine Semiconductor Corportation 16 Doc. 79/0072~00B Figure 5. failed.
