Evaluation Board User Guide
USING THE EVALUATION BOARD TO PROGRAM AN AD9520 ON A CUSTOMER BOARD
This guide shows how to use an AD9520 evaluation board to
program an AD9520 on a customer board via the I
It assumes that the user has access to the I
on the target board, and knows the assigned address of the
target I

Select the desired I
board using Jumper S5 and Jumper S6. Note that the S5 =
S6 = high setting is reserved for SPI mode. Also, this I
address should not conflict with the I
target AD9520.
Attach a jumper cable from SDIO_SDA pin of Header P1
of the evaluation board to the SDA pin on the target board.
Repeat Step 4 for both the SCLK_SCL pin and GND pin of
the AD9520 evaluation board to the SCL pin and ground
pin of the target board, respectively. On the evaluation
software, select Configure Serial Port from the I/O menu.
This window is shown in Figure 28.

Click Reset Serial Port and then click Detect Current
Configuration. A dialog box appears and acknowledges
the I
I
that it finds. If the target I
one automatically selected, select the I
target AD9520 from the list, and click OK.
From the View menu on the menu bar (see Figure 24), and
select Debug. Click the I2C Debug button. The window
shown in Figure 29 appears.
Enter the I
the AD9520 evaluation board, and click Ping. The user
should see a green ACK message as shown in Figure 29.
Repeat this step for the I
ACK is returned for both addresses, the remote AD9520 is
ready to be programmed.
If the ping test fails, double-check the cabling between the
boards, as well as the I
Ensure that the I
uation board is different from the target AD9520. Also,
disconnect the jumper cable, and make sure that I
is working properly on the AD9520 evaluation board.
Proceed to program the target AD9520 with the desired
settings. When finished, click the EEPROM button on the
main window to access the EEPROM window, and then
click Program EEPROM to write the settings to the
EEPROM.
