GENERAL DESCRIPTION

The EVAL-ADATE320EBZ is a full-featured evaluation board designed to allow the user to simply evaluate all features of the ADATE320 dual-integrated driver, comparator, and active load (DCL) with a per pin parametric measurement unit (PPMU). The EVAL-ADATE320EBZ features breakout connections through the Subminiature Version A (SMA) terminals for all of the signal inputs and outputs. The differential pairs are provided with 50 Ω-controlled impedance traces with equal lengths.

The EVAL-ADATE320EBZ only takes in +12 V and −8 V supplies, and the on-board regulators provide the required device supplies.

The EVAL-ADATE320EBZ can be controlled through the on-board connectors or through the USB port of a Windows-based PC using the ADATE320 Evaluation Board Software, which is available for download on the EVAL-ADATE320EBZ product page. The default setup is for control through the USB port. Communication with the ADATE320 Evaluation Software is through the USB, and the light emitting diode (LED) indicators on the EVAL-ADATE320EBZ provide displays for the read and write data.

The ADATE320 data sheet provides full details on the ADATE320, as well as the information on each of the registers within the ADATE320, and must be consulted when using the EVALADATE320EBZ.

QUICK START GUIDE

To run the EVAL-ADATE320EBZ with the ADATE320 for the first time, take the following steps:

Install the software. Note that the ADATE320 Evaluation Board Software must be installed before connecting the EVALADATE320EBZ or the USB communications may not function properly.
a. To install the required USB drivers and software to the
PC, download the ADATE320 Evaluation Board Software and run the setup.exe file. By default, all software, documentation, and setup files copy to C:\ProgramData\Microsoft\Windows\Start Menu\Programs\ADATE320 Evaluation Board Software.
Restart the PC.
Plug in the hardware.
a. Turn the following power supplies on:
► 12 V DC = 12 V
► −8 V DC = −8 V
► GND = 0 V
b. Using a USB cable, connect the EVAL-ADATE320EBZ to the PC. Most Windows PCs automatically install the USBdrivers the first time a powered FTDI chip is connected through the USB. However, the user can retrieve the drivers from the FTDI Chip D2XX Direct Drivers page, if required.
Open the ADATE320 Evaluation Board Software using one of the following options:
► Select the ADATE320 Evaluation Board Software in the Windows Start menu (see Figure 2).

► Search for the ADATE320 Evaluation Board Software using the Windows search feature, and then select the ADATE320 Evaluation Board Software in the results pane (see Figure 3).

Verify that the PC is communicating with the hardware.
a. When the ADATE320 Evaluation Board Software opens, the main window opens if there are no issues (see Figure 4). Otherwise, a command prompt indicating any error pops up. Figure 5 shows an example of an error prompt with four asterisks. Follow all the recommendations within the prompt window before attempting to start the software again.

b. To verify the hardware communication, click on the Reset Part button, and then click the Read all Regs button in the main window. If there is successful communication, the software user interface (see Figure 6) and command prompt (see Figure 7) reflect the default values (see the ADATE320 data sheet for more information). If the user interface and the command prompt do not reflect the default values, perform the following steps:

1. Close the ADATE320 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 ADATE320 Evaluation Board Software, click the Reset Part button, and then click the Read all Regs button again to confirm that the user interface (see Figure 6) and command prompt (see Figure 7) reflect the default values of the registers.

POWER SUPPLIES

Provide the following external power supplies:

12 V between 12 V DC and GND
−8 V between −8 V DC and GND

The GND input is provided on the EVAL-ADATE320EBZ. Each device supply is decoupled to GND with a 10 μF and 0.1 μF capacitor. Each device supply pin is again decoupled with a 0.1 μF capacitor to GND. See the Figure 13 and Figure 14 for reference.

USING THE EVAL-ADATE320EBZ

The EVAL-ADATE320EBZ requires two voltage supplies (+12 V and −8 V). The +12 V and −8 V supplies are enough to power the entire board including the digital portion. The EVAL-ADATE320EBZ also has SMA provision for both the inputs and outputs. The EVAL-ADATE320EBZ must be controlled through the USB and can be used with the provided software for simple access to user registers within the ADATE320. Designed to be interactive, the EVAL-ADATE320EBZ also features an LED array at the bottom portion to help the user know that the correct data are being written to or read from the device.

SOFTWARE OPERATION

To start the ADATE320 Evaluation Board Software, follow these steps:

Use the Windows search feature to find the ADATE320 Evaluation Board Software.
When the search displays the ADATE320 Evaluation Board
Software, select it. The main ADATE320 Evaluation Board
Software window opens as shown in Figure 4. Note that the software loads the adate320_default.sbus file upon startup.

The main ADATE320 Evaluation Board Software window provides controls for the main functions of the ADATE320, including access to the DAC registers. The main window of the ADATE320

Evaluation Board Software also includes the following panels:

The ADATE320 DAC Levels panel allows the user to write to the DACs within the ADATE320.
The Single Read from Part and Single Write to Part panels allow the user to read or write to a specific register, for example, the DAC register or the control register.
The control register panel allows the user to configure the settings of the ADATE320.

DAC LEVELS

The ADATE320 DAC Levels panel, located in the upper-left corner of the user interface (see Figure 4), lists all the current settings of the DACs within the ADATE320 (see Figure 8). Changing values in the number field and pressing Enter (on the keyboard) in the ADATE320 DAC Levels panel is equivalent to writing that value to the specific DAC. The corresponding value (hex code or voltage) changes accordingly.

SETUP FILE
The SETUP FILE panel allows the user to load or save register settings for all DAC and control registers for quicker testing by clicking the Load Setup button or the Save Setup button (see Figure 9).

To write the current DAC and control registers values displayed in the GUI to the ADATE320, click the Write All Reg button.

The user can read back the DAC and control registers from the ADATE320 and display each reading to the main window, as well as update the DAC levels and control registers of the GUI, by clicking the Read All Regs button.

The Write Read Ch0/1 dropdown menu allows users to set which channel the control registers panel sends the commands to. The user can select either one channel or both channels to be written at the same time. Note that this dropdown menu affects the writing and displaying of the control registers only and does not influence the Write All Reg, Read All Regs, Load Setup, or ADATE320 DAC Levels buttons.

The user can reset the device by clicking the Reset Part button.
To have the main window match the settings of the device after a reset, click Read all Regs.

To set the SCLK frequency, modify the Sclk Divider field and click the Set SCLK Freq button to apply the set value. Note that the higher the Sclk Divider value, the slower the SCLK is as shown by this equation:

SCLK = 60 MHz/(( 1 + SCLK Divider) × 2)
The FTDI232H, the microcontroller chip being used on the board, can also be reset through the Reset FTDI232H button.

SINGLE READ FROM PART AND SINGLE WRITE TO PART FUNCTIONS

The Single Read from Part and Single Write to Part functions of the user interface (see Figure 10) makes it easy for the user to write to or read from the specific registers as required. Note that when reading from a register, it is not necessary to fill the Data field as this field shows the data read from the device.

CONTROL REGISTERS

It is difficult for the user to manually fill the single write panel to configure the settings of the ADATE320, thus the control registers panel was added to address this. The control registers panel allows the modification of the settings of the ADATE320 by letting the user know which register is being written to, and what specific setting is being changed (see Figure 11). Alarms can also be read from this panel.
