Evaluation Board Hardware

The following instructions are for setting up the physical connections to the AD9508/PCBZ evaluation board. Before connecting the evaluation board to a PC for the first time, the user must install the evaluation software.

Power and PC Connections

Before installing the AD9508 evaluation software, uninstall prior versions of the software. Administrative privileges are required for installation. The 64-bit versions of are supported.

Connect the 6 V wall power supply to the main power connector labeled P500. Connect the USB cable to the evaluation board and the computer. The red LED labeled CR300 on
the AD9508 evaluation board should illuminate. If the Found New Hardware Wizard window appears when the evaluation board is connected,
select Install the software automatically and click Next. The Found New Hardware Wizard window may appear twice, and a system restart may be required. After the driver software has installed, the red LED labeled CR301 blinks.

Signal Connections

To connect signals, connect a signal generator to the J200 CLKIN SMA connector. By default, the CLKIN input is connected to a balun for single-ended to differential conversion. This path is differentially terminated to 100 and ac-coupled into the AD9508 reference inputs. An amplitude setting of 0 dBm to 6 dBm is fine. The CLKIN_B SMA input is grounded by default.

OUT0 through OUT3 are ac-coupled outputs differentially terminated to 100

Pin Programming and Jumper Settings

Jumpers P507, P100, and P101
q Jumper P507 allows the user to select between V and V operation.
q Jumper P100 allows the user to select between differential and single-ended inputs.
q Jumper P101 allows the user to select the programming method SPI/I2C/Sx pin programming to be used by the AD9508. Placing no jumper defaults the part to use the SPI. I2C programming is not currently supported with the evaluation board software. When pin programming is selected, Pin S0 through Pin S5 are used to determine various divider ratios and output modes for each of the AD9508 outputs.
