Section 3 lists the evaluation Kit contents. Sections 4 and 5 describe how to operate the evaluation board.3.0 Evaluation Kitthe evaluation kit contains the following contents:a.

For this we recommend a signal analyzer such as the agilent e5052B or equivalent. a high performance spectrum analyzer can be used as an alternative to the signal analyzer.Figure 2 highlights the major components and connectors on the Synthesizer evaluation Board.Figure 1.

General Schematic of Loop FilteraPLLs WITH INTEGRATED VCO - MICROWAVE APPLICATIONSEVALUATION BOARD OPERATING GUIDEv00.0112 cP120143140-00073-00 revA4.3.2 Passive Loop FilterBased on the general schematic above, some type of loop filters can be configured as follows.it should be noted that the op-amp is powered by a separate power supply, marked +15V.a. Passive Loop Filterthe Passive loop filter consists of c33, r13, c37, r21 and c61. it can be configured by removing r4, r23, r25, c65, shorting r12=0, and leaving +15V open.it should be noted that the maximum Vco tuning voltage of the passive loop filter is limited by the chargepump power supply, for example, +5V.Figure 5.

ActiveC Loop FilteraEVALUATION BOARD OPERATING GUIDE5.0Operating ProcedureStep 1. Setup the evaluation board as shown in Figure 1Step 2. turn +5.5V and +15V supplies on.Step 3. Launch the control program (located initial on the cd).Step 4. From the drop down list, select the part you are operating (for example, HMc778LP6ce).Figure 7.

Synthesizer Block DiagramaEVALUATION BOARD OPERATING GUIDEStep 8. Set rF frequency in “rF Frequency control” block.check “Manual override” and change “Vco to Prescaler” from “1” to “4” in Prescaler control block. For integer mode, type in the frequency desired, click “update Frequency” button as Figure 11 shown. user can click “open detailed gui ” button to see the detailed register window in integer mode as shown in figure 12.For fractional mode, check “Frac Mode” box first. then type in the frequency desired, click “update Frequency” button as Figure 13 shown. i n order to optimize the phase noise and spur performances in fractional mode, user should click “open detailed gui” button. the new detailed register control window pops out as shown in Figure 14. i n the “register 09: charge Pump register” block, check “Source cP offset” box or “Sink cP offset” box and select the calculated cP offset current from the pull down list of “cP offset” box. then click “write” button. the correct cP offset current is calculated by the following equation (see equation 4 on page 19 of HMc703LP4e datasheet).required cP offset current = (2.5*10e-9 + 4*tps)*Fcomp*icpusually this value will give the optimum performances on phase noise and spurs.Figure 11.

Scan the Vco frequency to find the synthesizer locked range (“Frac Mode” box must be checked).click “Scan Vco Frequency” button in the main control window (Figure 9). a new small window pops out as shown in Figure 15. Set “Start Freq”, “coarse Step” and “ Freq Max Limit”, click “Start Scan” button (refer to the specified Min/Max frequencies of the particular part in the datasheet, set “Start Freq” to Min frequency and set “Freq Max Limit” to 1 gHz above Max frequency). When the scan is finished, the synthesizer locked range will be shown in the window. as an example, Figure 16 shows the scan setting and scan result on HMc778LP6ce. remember that the frequency lock range is greater than the specified frequency range and the phase noise or spurs will degrade outside of this specified window.Step 10. run frequency hopping (optional).click “Frequency Hop” button in the main control panel (Figure 9). a new small window pops out as shown in Figure 17. Set “Frequency #1”, “Frequency #2” and “dwell time” in this window. then click “Start” button. the rF signal will switch between “Frequency #1” and “Frequency #2” in the defined “dwell time”. Figure 18 shows a typical example of the “Frequency Hop” setting on the HMc778LP6ce. this function usually is used to find the frequency settling time of the synthesizer.Figure 15.
