The EV kit includes an evaluation board and a graphical user interface (GUI) that provides communication from the target device to the PC through a ZedBoard™ with a Xilinx Zynq® -7000 SOC. The EV kit is connected to a ZedBoard through a low-pin-count FMC connector and a ZedBoard connected to the PC through an Ethernet port.The EV kit includes Windows XP®, Windows® 7 and Windows 8 compatible software for exercising the features of the IC. The EV kit GUI allows different sample sizes, adjustable sampling rates, and graphing software that includes the FFT and histogram of the sampled signals.The EV kit can be powered by +12V supply from ZedBoard or by an external power supply. The EV kit has two DC-DC converters and 5V LDO which provide all necessary supplies for operation with ZedBoard.The MAX11198 EV kit comes installed with a MAX11198ATE+ in a 16-pin, 2mm x 3mm TQFN-EP package.The EV kit aims to be used with an external resolver or encoder to monitor and measuring degrees of rotation or absolute position of the rotor at any given moment.

General Description of SoftwareThe main window of the EV kit software contains five tabs: System, Scope, DMM, Histogram, and FFT. The System tab provides control for the ADC configuration including calibration and single data capture. The other four tabs are used for evaluating the data captured by the ADC.

System TabThe System tab allows to select Sample Rate, Number of Samples, Clock Source for coherent sampling and for SPI interface, as well as EV kit Device resolution from

corresponding pulldown menu. There is a block diagram of the EV kit and Calibration section for convenience.The Read Data information is displayed on the right, which shows the data in both voltage and LSB, see Figure 1.

Sample Rate (SPS)To select the desired data rate choose the Sample Rate (SPS) pulldown menu. The sampling rate is available from 1000sps to 2000000sps.

Number of SamplesThe Number of Samples pulldown menu allows choosing from 1 up to 1048576 samples to be captured.

Figure 1. EV Kit Software (Configuration Tab)



Reference Voltage The Reference Voltage selection should match with the jumper settings refer to Table 2. A user can select either internal or external reference voltage. The internal refer-ence is fixed to 2.5V. The external reference can be from 2.5V to 4.75V. Use “+” or “-″ buttons to adjust the actual voltage reference, or simply type in a new value.

ADC CalibrationThe ADC Calibration section allows to calibrate each channel independently.

Scope TabThe Scope tab sheet is used to capture data and display it in the time domain. The desired Sampling Rate, Number

of Samples, Display Unit, Average Samples, and Resolution Selection can be set in this tab if they were not appropriately adjusted in other tabs. The Display Unit pull-down list allows counts in LSB and voltages in V, mV, or µV. Once the desired configuration is set, click on the Capture button. The right side of the tab sheet displays details of the waveform, such as average, standard devia-tion, maximum, minimum, and fundamental frequency for each channel as shown in Figure 2.To save the captured data to a file, select Options > Save Graph > Scope. This saves the setting on the left and the data captured to a CSV file.

Figure 2. EV Kit Software (ScopeTab)



DMM TabThe DMM tab sheet provides the typical information as a digital multimeter. Once the desired configuration is set, click on the Capture button. Figure 3 displays the results shown by the DMM tab when no signal is applied to both channels.Histogram TabThe Histogram tab sheet is used to show the histogram of the data. Sampling rate and number of samples can also be set in this tab if they were not appropriately adjusted in other tabs. Once the desired configuration is set, click on the Capture button. The right side of the tab sheet displays details of the histogram such as average, standard deviation, maximum, minimum, peak-to-peak noise, effective resolution, and noise-free resolution as shown in Figure 4.The histogram tab is enabled at default. Using the his-togram will slow down the GUI response. To disable it, check the Disable Histogram box.

To save the histogram data to a file, go to Options > Save Graph > Histogram. This saves the setting on the left and the histogram data captured to a CSV file.

FFT TabThe FFT tab sheet is used to display the FFT of the data. The Sample Rate, Number of Samples, Resolution Selection, and type Window Function can be set as desired. To calculate the Adjusted Input Signal fre-quency for Coherent Sampling, type in the Input Signal frequency in Hertz and GUI automatically calculates the master clock needs to be applied for coherent sampling and vice versa. Once the preferred configuration is set, click on the Capture button. The right side of the tab displays the performance based on the FFT, such as fun-damental frequency, SNR, SINAD, THD, SFDR, ENOB, and Noise Floor as shown in Figure 5.To save the FFT data to a file, go to Options > Save Graph > FFT. This saves the setting on the left and the FFT data captured to a CSV file.

Figure 3. EV Kit Software (DMM Tab)



Figure 4. EV Kit Software (Histogram Tab)

Figure 5. EV Kit Software (FFT Tab)



When coherent sampling is needed, this tab allows the user to calculate the input signal applied to the board. Adjust the input frequency of the low-jitter clock to the value as shown in the Adjusted Input Signal (Hz) and apply it to the EV KIT SYNC_CLK_IN connector. See the Sync Input and Sync Output section before using this feature. Figure 6 shows the setup Maxim Integrated uses to cap-ture data for coherent sampling.Figure 7 shows the coherent FFT signal. Use the jumper settings from Table 2 for proper configurations. The low-jitter clock is synchronized with the signal gen-erator at 10MHz from the ZedBoard. To achieve coherent sampling, click on the Calculate button and enter the Adjusted Input Signal (Hz) into low-jitter clock. Timing for all SPI timing and sampling rate are based off the system clock.

User-Supplied SPI To evaluate the EV kit with a user-supplied SPI bus, disconnect the board from the ZedBoard. Apply the user-supplied SPI signals to SCLK, CNVST, DOUT1, and DOUT2 to J17. Make sure the return ground from J17.15 is connected to master ground.

FMC InterfaceThe users should confirm compatibility of pin-usage between their own FMC implementation and that of the MAXIM EV kit before connecting the MAXIM EV kit to a different system with FMC connectors.

External OVDD Power SupplyAn external OVDD voltage can supply to TP12 in range from 1.8V to 3.6V. The J15 shunt should be set in 1-2 position.

User-Supplied Power SupplyThe EV kit receives power from ZedBoard or from a single DC source of 12V, 200mA through a J26 power jack. The two MAX17552 DC-DC converters generate +6.5V and -6.5V for the buffers, U1 and U2, and differential amplifi-ers, U3 and U4. The +6.5V power is then regulated down to a +5V by MAX15006B for U5. See the EV kit schematic for details. User can supply an external +6.5V to TP22 and -6.5V to TP21 to reduce the influence of DC-DC con-verter switching frequency. In this case, the J23, J24 and J25 shunts must be removed.

ADC Input AmplifiersThe analog front-end conditioner for each channel includes the input low-pass filter (1k resistor and 1000pF capacitor), the MAX44242 input buffer and the MAX44205 fully differential amplifier.

Sync Input and Sync Output (for coherent sampling)Sync Input and Sync Output is applicable to the FPGA (ZedBoard) and is not used in Standalone mode. Sync Input and Sync Output The SYNC_IN SMA accepts an approximate 100MHz waveform signal to generate the system clock of the ZedBoard. For maximum perfor-mance, use a low-jitter clock that syncs to the user’s analog function generator. The SYNC_OUT SMA outputs a 10MHz square waveform that syncs to the user’s analog function generator. Both options are used for coherent sampling of the IC. Use only one option at a time. The relationship between fIN, fS, NCYCLES, and MSAMPLES is given as follows:
