The high speed ADC FIFO evaluation kit includes the latest version of ADC Analyzer and a buffer memory board to capture blocks of digital data from the Analog Devices high speed analog-to-digital converter (ADC) evaluation boards. The FIFO board is connected to the PC through a USB port and is used with ADC Analyzer to quickly evaluate the performance of high speed ADCs. Users can view an FFT for a specific analog input and encode rate to analyze SNR, SINAD, SFDR, and harmonic information.
The evaluation kit is easy to set up. Additional equipment needed includes an Analog Devices high spe
ed ADC evaluation board, a signal source, and a clock source. Once the kit is connected and powered, the evaluation is enabled instantly on the PC.  Two versions of the FIFO are available. The HSC-ADC-EV ALB-DC is used with multichannel ADCs and converters with demulti-plexed digital outputs. The HSC-ADC-EV ALB-SC evaluation board is used with single-channel ADCs. See Table 1 to choose the FIFO appropriate for your high speed ADC evaluation board.

PRODUCT HIGHLIGHTS
1.Easy to Set Up. Connect the included power supply and signal sources to the two evaluation boards. Then connect
to the PC and evaluate the performance instantly.
2.ADIsimADC™. ADC Analyzer supports virtual ADC evaluation using ADI proprietary behavioral modeling technology. This allows rapid comparison between multiple ADCs, with or without hardware evaluation boards. For more information, see AN-737 at www.analog/ADIsimADC.
3.USB Port Connection to PC. PC interface is a USB 2.0 connection (1.1-compatible) to the PC. A USB cable is provided in the kit.
4.32 kB FIFO. The FIFO stores data from the ADC for processing.
A pin-compatible FIFO family is used for easy upgrading.
5.Up to 133 MSPS Encode Rate on Each Channel. Single-channel ADCs with encode rates up to 133 MSPS can be used with the FIFO board. Multichannel and demultiplexed output ADCs can also be used with the FIFO board with clock rates up to 266 MSPS.
6.Supports ADC with Serial Port Interface or SPI. Some ADCs include a feature set that can be changed via the SPI. The FIFO supports these SPI-driven features through the existing USB connection to the computer without additional cabling needed.

FIFO EVALUATION BOARD EASY START
REQUIREMENTS
• FIFO evaluation board, ADC Analyzer, and USB cable • High speed ADC evaluation board and ADC data sheet • Power supply for ADC evaluation board • Analog signal source and appropriate filtering • Low jitter clock source applicable for specific ADC evaluation, typically <1 ps rms
• PC running Windows 98 (2nd ed.), Windows 2000, Windows Me, or Windows XP
•
PC with a USB 2.0 port recommended (USB 1.1-compatible)
EASY START STEPS
Note: Y ou need administrative rights for the Windows operating systems during the entire easy start procedure.  It is recommended to complete every step before reverting  to a normal user mode.
1. Install ADC Analyzer from the CD provided in the FIFO
evaluation kit or download the latest version on the Web. For the latest updates to the software, check the Analog Devices website at www.analog/hsc-FIFO . 2. Connect the FIFO evaluation board to the ADC evaluation
board. If an adapter is required, insert the adapter between the ADC evaluation board and the FIFO board. If using the HSC-ADC-EV ALB-SC model, connect the evaluation board to the bottom two rows of the 120-pin connector, closest to the installed IDT FIFO chip. If using an ADC with a SPI interface, r
emove the two 4-pin corner keys so that the third row can be connected. 3. Connect the provided USB cable to the FIFO evaluation
board and to an available USB port on the computer. 4. Refer to Table 5 for any jumper changes. Most evaluation
boards can be used with the default settings. 5. After verification, connect the appropriate power supplies
to the ADC evaluation boards. The FIFO evaluation board is supplied with a wall mount switching power supply that provides a 6 V , 2 A maximum output. Connect the supply end to the rated 100 ac to 240 ac wall outlet at 47 Hz to  63 Hz. The other end is a 2.1 mm inner diameter jack that connects to the PCB at J301. Refer to the instructions included in the ADC data sheet  for more information about the ADC evaluation board’s power supply and other requirements.    6. Once the cable is connected to both the computer and the
FIFO board, and power is supplied, the USB drivers start to install. To complete the total installation of the FIFO drivers, you need to complete the new hardware sequence two times. The first Found New Hardware  Wizard  opens with the text message This wizard helps you install software for…Pre-FIFO 4.
1. Click the recommended install, and go to the next screen. A hardware installation warning window should then be displayed. Click Continue Anyway . The next window that opens should finish the Pre-FIFO 4.1 installation. Click Finish . Y our computer should go through a second Found New Hardware Wizard , and the text message, This wizard helps you install software for…Analog Devices FIFO 4.1, should be displayed. Continue as you did in the previous installation and click Continue  Anyway . Then click Finish  on the next two windows. This completes the installation.  7. (Optional) Verify in the device manager that Analog
Devices, FIFO4.1 is listed under the USB hardware. 8. Apply power to the evaluation board and check the voltage
levels at the board level. 9. Connect the appropriate analog input (which should be
filtered with a band-pass filter) and low jitter clock signal. Make sure the evaluation boards are powered on before connecting the analog input and clock. 10. Start ADC Analyzer.
11. Choose an existing configuration file for the ADC
evaluation board or create one. 12. Click Time Data in ADC Analyzer  (left-most button under
the menus). A reconstruction of the analog input is
displayed. If the expected signal does not appear, or if there is only a flat red line, refer to the ADC Analyzer data sheet at www.analog/hsc-FIFO  for more information.

VIRTUAL EVALUATION BOARD EASY START WITH ADIsimADC
REQUIREMENTS
Requirements include • Completed installation of ADC Analyzer, Version 4.5.17 or later.
•
ADIsimADC product model files for the desired converter. Models are not installed with the software, but they can be downloaded from the ADIsimADC Virtual Evaluation Board website at no charge.
No hardware is required. However, if you wish to compare
results of a real evaluation board and the model, you can switch easily between the two, as outlined in the following Easy Start Steps section.
EASY START STEPS
1. To get ADC model files, go to www.analog/ADIsimADC
for the product of interest. Download the product of
interest to a local drive. The default location is c:\program files\adc_analyzer\models. 2. Start ADC Analyzer (see the ADC Analyzer User Manual ). 3. From the menu, click Config  > Buffer  > Model  as the
buffer memory. In effect, the model functions in place of the ADC and data capture hardware.  4. After selecting the model, click the Model  button (located
next to the Stop  button) to select and configure which converter is to be modeled. A dialog box appears in the workspace, where you can select and configure the behavior of the model.      5. In the ADC Modeling  dialog box, click the Device  tab and
then click the … (Browse) button, adjacent to the dialog box. This opens a file browser and displays all of the models found in the default directory: c:\program files\adc_analyzer\models. If no model files are found, follow the on-screen directions or see Step 1 to install available models. If you have saved the models somewhere other than the default location, use the browser to navigate to that location and select the file of interest. 6. From the menu, click Config  > FFT . In the FFT
Configuration  dialog box, ensure that the Encode
Frequency  is set for a valid rate for the simulated device under test. If set too low or too high, the model does not run. 7. Once a model has been selected, information about the
model displays on the Device  tab of the ADC Modeling dialog box. After ensuring that you have selected the right model, click the Input  tab. This lets you configure the input to the model. Click either Sine Wave  or Two Tone  for the input signal. 8. Click Time Data  (left-most button under the pull-down
menus). A reconstruction of the analog input is displayed . The model can now be used just as a standard evaluation board would be. 9. The model supports additional features not found when
testing a standard evaluation board. When using the modeling capabilities, it is possible to sweep eithe
r the analog amplitude or the analog frequency. For more information consult the ADC Analyzer User Manual  at  www.analog/hsc-FIFO .
