GENERAL DESCRIPTION

The EVAL-ADATE304BBCZ is a full featured evaluation board designed to allow the user to simply evaluate all features of the ADATE304 dual integrated driver, comparator, and active load (DCL) and four-quadrant per pin parametric measurement unit (PPMU). The EVAL-ADATE304BBCZ features breakout connections through the SMA terminals for all the signal inputs and outputs. The differential pairs are provided with 50 Ω controlled impedance traces with equal lengths.
The EVAL-ADATE304BBCZ only requires two power supplies, +21 V and −10 V. All other voltages required by the device are created by the on-board regulators. The EVAL-ADATE304BBCZ SPI communications are provided by an on- board USB UART chip. SPI jumper connectors allow the user to bypass the UART and connect their own SPI signals for evaluation (see Table 1). The default setup is for control through the USB port. Communication with the ADATE304  evaluation board software is through the USB, and the light emitting diode (LED) indicators on the EVAL-ADATE304BBCZ provide displays for the read and write data.
The ADATE304 data sheet provides full details on all the functionalities of the ADATE304 device, as well as the information on each of the registers within the
ADATE304, and must be consulted when using the EVAL-ADATE304BBCZ.

QUICK START GUIDE
To run the EVAL-ADATE304BBCZ with the ADATE304 for the first time, take the following steps:

1. Install the software. Note that the evaluation software must be installed before connecting the EVAL-ADATE304BBCZ, or the USB communications may not function properly. To install the required USB drivers and software to the  PC, download the ADATE304 Evaluation Software and run the adate304install.exe file. By default, all software, documentation, and setup files copy to C:\ProgramData\Microsoft\Windows\Start Menu\Programs\ADATE304  Evaluation Board Software.

2. Restart the computer.

3. Plug in the hardware.
   a. Turn the following power supplies on:
   ► 21 V DC = 21 V
   ► −10 V DC = −10 V
   ► GND = 0 V
   b. Using the USB cable, connect the EVAL-ADATE304BBCZ to the PC. Most Windows computers automatically install the USB drivers the first time a powered FTDI chip is connected through the USB. However, the user can  retrieve the drivers from the FTDI D2xx direct drivers page, if required.
   c. The FTD2XX.dll can also be found in C:\Program Files (x86)\ADATE304 Evaluation Board Software\Dace.

4. Open the ADATE304 evaluation software using one of the following options:
   ► Select the ADATE304 Evaluation Board Software in the Windows Start menu (see Figure 2).► Search for the ADATE304 Evaluation Board Software using the Windows search feature, and then select the ADATE304 Evaluation Board Software in the results pane (see Figure 3).

5. Verify that the PC is communicating with the hardware.
   a. When the ADATE304 Evaluation Board Software opens, the main window opens if there are no issues (see Figure4) and displays configuration success (see Figure 8). Otherwise, a command prompt indicating any error appears.
   Figure 5 shows an examples of error prompt. Follow all the recommendations within the prompt window before attempting to start the software again.

b. To improve the viewing experience of the software user interface, the user can set the custom scale size of a display of PC or laptop by following these steps:

1. Open settings then click on System.
2. Go to Display.
3. In the Scale and layout section, choose the 100% scale setting by using the scale drop-down box.
4. Restart the software to apply changes. Note that Figure 6 is based on Windows 10.

c. To verify the hardware communication, load the
ADATE304 Default Test Conditions. Bus file. If the EVALADATE304BBCZ successfully communicates with the PC, the software user interface (see Figure 7) reflects the default values (see the ADATE304 data sheet for more information). If the user interface does not reflect the default values, perform the following steps:

1. Close the ADATE304 Evaluation Board Software.
2. Disconnect the USB cable.
3. Turn off the power supply.
4. Activate the power supply again.
5. Reconnect the USB cable.
6. Open the ADATE304 Evaluation Board Software, the command prompt displays configuration success (see Figure 8). Then, load the ADATE304 Default Test Conditions. Bus file to confirm if the user interface reflects the default values of the registers (see Figure 7).

USING THE EVAL-ADATE304BBCZ
The EVAL-ADATE304BBCZ requires two voltage supplies (+21 V and −10 V). The +21 V and −10 V supplies are enough to power the entire board including the digital portion. The evaluation board also has an SMA provision for both the inputs and outputs. The EVAL-ADATE304BBCZ must be controlled through the USB and can be used with the provided software for easy access to user registers within the ADATE304. Designed to be interactive, the EVAL- ADATE304BBCZ also features an LED array at the bottom portion to notify the user that the correct data is being written to or read from the device.

ADATE304 EVALUATION BOARD NOTES
When using the EVAL-ADATE304BBCZ, the following are some important information to take note:
► VREF_POT, the blue trimmer resistor located near the middle of the EVAL- ADATE304BBCZ evaluation board, is used to adjust the 5 V reference to the DUT.
► The 5 V reference can be monitored on VREF_TP, which is nearby, while adjusting VREF_POT. It has been set but can be adjusted if desired.
► Adjusting VPLUS, VDD, and VSS supplies between the two power supply ranges requires the use of VPLUS_POT, VDD_POT, and VSS_POT. The values of power supply with respect to the range used are listed in Table 2.  ET_RANGE1_JMPR is inserted by default.

Table 2. Power Supply Ranges

► Place jumpers on VPLUS_JMPR, VCC_JMPR, VTT_JMPR, VDD_JMPR, and VSS_JMPR during normal operation. These terminals are also used to check the current flowing through the supply.
► Near GND_TP4 and the U3 IC are two LEDs. When activated, SDI_SH LED indicates a serial data bus write to the ADATE304, and the serial bus LED field reflects the data written out. Conversely, the SDO_SH LED, when activated,  indicates a serial bus read from the ADATE304 and that the EVAL- ADATE304BBCZ serial bus LED bank is reading from the DUT.
► The SDO_SH LED and serial bus LEDs do not reflect the whole SPI read word, due to limits on the hardware circuitry or software programming. Disregard LED CH1 to A0 when reading.
► The device and FTDI microcontroller connection can be reset manually by pressing DUTRST and USB_RS, respectively.
► Handle with care and operate only if there are standoffs connected.

SOFTWARE OPERATION
The software provides a graphical user interface to control the ADATE304 serial bus. The serial bus provides control for the internal DAC levels and modes of operation of the device, as described in the ADATE304 data sheet. Windows 7  SP1 is required at a minimum. No Mac version is currently available.
To start the ADATE304 Evaluation Board Software, follow these steps:

1. Use the Windows search feature to find the ADATE304 Evaluation Board Software.
2. When the search displays the ADATE304 Evaluation Board Software, select it. The main ADATE304 Evaluation Board Software window opens as shown in Figure 4. Load the adate304_default.sbus file after startup.

The main ADATE304 Evaluation Board Software window provides controls for the main functions of the ADATE304, including access to the DAC registers. The main window of the ADATE304 Evaluation Board Software also includes the following panels:
► The ADATE304 DAC levels panel allows the user to write to the DACs within the ADATE304.
► The single read and write panel allows the user to write single word commands and single register readbacks to or from the ADATE304 if so desired.
► The mode selection controls panel located on the right side of the GUI (see Figure 12), allows the user to configure the settings of the ADATE304.
► The FT reset and clock speed controls are located in the lower right of the GUI (see Figure 4).
DAC LEVELS
The ADATE304 DAC levels panel, located in the upper-left corner of the user interface, lists all the current settings of the DACs within the ADATE304 (see Figure 9). Each channel has their individual registers, which means each register can be edited individually. Single Write button in Figure 10 can be used to write on both channels at the same time. DAC values in the DAC levels panel can also be changed in real time by clicking on the up-down arrows in the corresponding box. If a Voltage value is selected with the cursor and a value typed into the window, it is changed when either the mouse is clicked on the entry value or the enter key on the keyboard is pressed. Note that the DAC levels or Voltage is limited to the numbers stated in the data sheet. Typing a greater or lesser value than the maximum or minimum value prompts the software to write the maximum or minimum value instead. This is true for Address, CH, and Data as well on single writes/reads. Either the DAC levels or Voltage can be changed and the other changes accordingly.

LOAD FILE SETTINGS
The Load Settings and Save Settings panel allows the user to load or save register settings for all DAC and control registers for quicker testing, by clicking the Load Settings button or the Save Settings button (see Figure 10).
The Load Settings button prompts the user to choose a previously created setup file. The file updates the GUI and writes changed values out to the ADATE304. All DAC Level values and all mode controls can be saved by clicking the Save Settings button. The user is prompted to provide a file name under which all the settings are saved.
In the lower left section, clicking on the Single Write button writes the data-word shown in the controls (CH, Address, Data) to the serial bus of ADATE304. The values of the controls can be manually changed by placing the cursor in the box and clicking and entering the desired value. The Address and Data controls are in hex while CH is in binary. Inputs on CH can be same with the binary stated on the data sheet. Changes made using single write updates the software corresponding to that change. All inputs made to the controls are written to the device when the Single Write button is clicked.
The Single Read button reads back the register that is addressed in its Address text box. The data is shown only in the RDATA indicator, and it is in hexadecimal format only.
The Read All button reads back the corresponding register value from the ADATE304 and displays it in the software. This button can be used to check if the chip and the software settings are in sync.

EVALUATION BOARD SOFTWARE

SCLK FREQUENCY, RESET ADATE304, RESET FT, EXIT PROGRAM
In the lower right section, SCLK Frequency can be used to change the frequency of the SCLK. Only certain frequencies are allowed due to the limitations of the hardware. Thus, the nearest allowed frequency is used instead of the user input, unless the one input is allowed. To set the SCLK Frequency, press the enter key (on the keyboard) to apply the set value to the SCLK Frequency box.
The Reset ADATE304 button resets the device and automatically reads the device. The connection between FTDI and PC can also be reset through the Reset FT button. Closing the program through Exit Program also resets the device.

MODE SELECTION CONTROLS
The mode selection controls panel allows the modification of the settings of the ADATE304 by letting the user know which register is being written to, and what specific setting is being changed (see Figure 12). Alarms can also be read  from this panel. At the top left of the GUI, Channel is a drop-down box that controls which channel the mode selection control section is sending commands to. Single Write must be used to write to both channels at the same time. The  mode selection controls panel of the GUI places the DCL in its various states as described in the ADATE304 specification. See the ADATE304 data sheet for a detailed description of the registers.
