Press “Done”, the Hittite PLL Evaluation Software GUI shown in Figure 3 will appear. Figure 3. PLL Main Control GUI 3. Load the register file. a. Press the “Load Reg File” button flashing in the lower right corner of the display. Navigate to register setting files corresponding to the device under test. b. Select the file according to the desired mode of operation, Fractional or Integer. For PLL with Integrated RF VCO devices select the register file for fo/2 (Divider), fo (Fundamental) or 2fo (Doubler) Mode as needed. fo/2, fo, 2fo Mode switching is performed by running the specific register file. c. The Check Lock section should now display the green ‘LOCKED’ display indicator. 4. Consult the Product Operation Guide available on www.hittite.com or provided on the CD-ROM for detailed instructions on PLL programming and debugging. 6 Order On-Line: www.hittite.com.

PLL Programming 5.1 Frequency Selection To program the PLL to a desired frequency, enter the frequency in the “OUT Freq Desired” box and press the “Update Frequency” button (Reference divider and VCO divider registers are only updated when the “Update Frequency” button is pressed). The “OUT Freq (Actual)” box displays the frequency that the PLL is actually generating. The “Error” box displays the frequency error between the desired and actual frequencies. 5.2 External or Internal Fixed Dividers Often, there will be dividers and/or doublers used between the VCO and the PLL’s prescaler, and/or between the VCO and the measurement equipment. For the GUI to calculate the correct N for the PLL, it needs to know the ratio between the “OUT Freq Desired” and the prescaler input. For standard Hittite parts, in “Auto” mode, the SW determines the value based on the selected part number, and the programmed register settings. If the user is using external dividers or multipliers, however, the “Manual Override” should be selected, and the frequency relationship between the VCO and output, and VCO and Prescaler need to be specified by the user. A block diagram ( ) of the PLL system is available by clicking on the “HMC PLL Block Diagram” button on the PLL Main Control GUI. The diagram may not be exactly as shown depending on the device and configuration. Some PLLs may have a fixed divider internal to the PLL in the loop. Figure 4.

It is recommended to run the provided register file for the desired mode (Fractional or Integer) for best spectral performance as there are other registers that need configuring when changing between these two modes. 5.5 Frequency Scan A convenient Scan feature is included to find the locking range of the PLL/VCO combination. Press the “Scan VCO Frequency” button and select “Start Scan” to use the default start scan parameters. The software will start programming different frequencies looking for lock, sweeping out the operating frequency range. The upper, lower and center frequencies are reported on the form. 5.6 Check Lock The “LOCKED”/”UNLOCKED” indicator is updated every time the “Update Frequency” button is pressed. You can confirm the locked state at any time by pressing the “Check Lock” button. 5.7 Frequency Hopping When performing settling time measurements, the PLL can also be configured to hop between two specified frequencies entered in the “Frequency Hop” window. The “Dwell Time” is not well calibrated and only offers a crude time estimation. It should not be relied upon for accurate hop timing. 5.8 Register Read/Write “SPI Read/Write” buttons provide direct register read/write capability in Hex. These are debug tools. To observe all the detailed register states, click the “Open Detailed GUI” button and the window in Figure 5 will open. Each register is controlled by its own “Read” and “Write” button in its sub-panel. Changes made by clicking on any check box are only implemented upon clicking that register’s “Write” button. Similarly a panel is only updated after the “Read” button is clicked. 8 Order On-Line: www.hittite.com.

Typical PLL GUI (varies by PLL model) 5.9 PLL Configuration Save/Load To save a PLL configuration to a file, use the “Save Reg File” button in the bottom right corner of the “PLL Main Control GUI”. This allows you to instantly recall the desired PLL state by using the “Load Reg File”. Saving a “Register” file for PLL with Integrated RF VCO devices does not capture the “Mode” state (fo/2, fo, 2fo). Further instructions on the operation of the PLL with Integrated Microwave VCO products can be found in the Evaluation Board Operating Guide available on www.hittite.com or on the CD-ROM.

Hittite PLL Design Tool Hittite PLL Design Software is a powerful tool that can be used to model and analyze performance of Hittite’s PLLs. The tool can be used to: • Model Integer and Fractional-N PLL performance • Design loop filter component values • Model and analyze individual and composite noise contributions • Model frequency and phase settling time The PLL Design & Analysis Tool uses MathWorks’ MCR (Matlab Compiler Runtime) Library which is included in the installation package. Hittite Microwave Corporation’s limited rights to the deployment of MCR are governed by a license agreement between Hittite Microwave Corporation and MathWorks. 6.1 Using the Hittite PLL Design & Analysis Tool 1.

Press the ‘Compute’ button in the lower right corner to graphically display simulated performance data. 3. Design an optimal loop filter by clicking on the Filter Design button to open the Loop Filter Design dialog. The Loop Filter Design tool provides various loop filter topology options and configurations. 4. Edit individual noise contributors ranging from crystal oscillator, reference path, phase detector, VCO, RF divider, operational amplifier, delta-sigma modulator, etc. by clicking on Noise Contributors button. a. Model and simulate the effect of VCO gain variation across VCO tuning range. b. Model and analyze the effect of power supply noise on the loop performance from various PLL components. 5. View graphical displays of various modelled performance metrics by choosing the desired category from the Select Plot Type drop down menu. 6. Observe modelled loop parameters summary from Loop Parameters display. 7. Generate detailed HTML reports outlining simulation setup and resulting performance by selecting Generate Reports from the Tools menu. 7.
