EVALUATION BOARD SOFTWARE QUICK START PROCEDURES

This section provides quick start procedures for using the AD9272/ AD9273 either on the evaluation board or in a system level design. Both the default and optional settings are described.

CONFIGURING THE BOARD

Before using the software for testing, configure the evaluation board as follows:

1.Connect the evaluation board to the data capture board as shown in Figure 1 and Figure 2.

2.Connect one 6 V, 2.5 A switching power supply (such as the CUI Inc. EPS060250UH-PHP-SZ supplied) to the AD9272/AD9273 board.

3.Connect one 6 V, 2.5 A switching power supply (such as the CUI EPS060250UH-PHP-SZ supplied) to the HSC- ADC-EVALCZ board.

4.Connect the HSC-ADC-EVALCZ board (J6) to the PC with a USB cable.

5.On the ADC evaluation board, place jumpers on all four pin pairs of J601 to connect the SPI bus.

6.On the ADC evaluation board, ensure that J401 (OSC_EN) is jumpered to the on setting to use the on-board 50 MHz/ 65 MHz/80 MHz Valpey Fisher VFAC3 oscillator.

7.On the ADC evaluation board, use a clean signal generator with low phase noise to provide an input signal to the desired channel. Use a 1 m, shielded, RG-58, 50 Ω coaxial cable to connect the signal generator. For best results, use a narrow-band band-pass filter with 50 Ω terminations and an appropriate center frequency. (Analog Devices uses TTE, Allen Avionics, and K&L band-pass filters.)

USING THE SOFTWARE FOR TESTING

Setting Up the ADC Data Capture Block

After configuring the board, set up the ADC data capture block using the following steps:

1.Open VisualAnalog™ on a PC. AD9272 or AD9273 should be listed in the status bar of the New Canvas window. Select the template that corresponds to the type of testing to be performed (see Figure 3).

2.After the template is selected, a message appears, asking if the default configuration can be used to program the FPGA (see Figure 4). Click Yes, and the window closes.

If a different program is desired, follow Step 3.

3.To view different channels or change features to settings other than the default settings, click the Expand Display button. This is located on the bottom right corner of the window, as shown in Figure 5.

This process is described in the AN-905 Application Note,

VisualAnalog Converter Evaluation Tool Version 1.0 User Manual. After you are finished, click the Collapse Display button (see Figure 6).
