| === Signal Connections === | ==== 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 100Ω and ac-coupled into the AD9508 reference inputs. An amplitude setting of 0 dBm to 6 dBm is fine. The CLKINB SMA input is grounded by default. To input a differential signal, the user must remove balun (T200) and resistor R221 and place resistors R209 and R210 with 0Ω. Connect an oscilloscope, spectrum analyzer, or other lab equipment to any of the J209 to J216 SMA clock OUT connectors on the edge of the board. OUT0 through OUT3 are ac-coupled outputs differentially terminated to 100Ω. | To connect signals, connect a signal generator to the J200 (CLKIN) SMA connector.

| === Pin Programming and Jumper Settings === | ==== Pin Programming and Jumper Settings ==== |
| **Jumper P507** allows the user to select between 2.5V and 3.3V operation. \\ \\ | |
| **Jumper P100** allows the user to select between differential (LVDS/ PECL/ etc) and CMOS input logic types.\\ \\ | |
| **Jumper P101** allows the user to select which programming method (SPI/I2C/S-pin programming) will be used by the AD9508. Placing no jumper defaults the part to use SPI. I2C is not currently supported with the evaluation board software. When pin programming is selected, S-pins S0 through S5 are used to determine various divider ratios and output modes for each of the AD9508s outputs. Using the S-pins to program the part gives the user limited control of each channel divider ratio and no control of phase offset. Please refer to the [[adi>AD9508|AD9508 datasheet]] for a complete overview regarding the use of the part with S-pin programming.\\ \\ | |

| The **Output Distribution** section allows the user to alter divide ratios and phase offsets for each output of the AD9508. Each divide and phase block can be edited by typing the preferred value within the block followed by **ENTER**. Once enter is pressed, the values are loaded into the evaluation board. The phase offset blocks accept the prefixes u (micro), p (pico), and n (nano). Phase offset is limited to one half of the period of the input clock rate. Each divider supports integer divide values from 1 to 1024. If the typed value is not realizable in the current configuration, the software will automatically round to the nearest possible solution. The output distribution section is shown in Figure 6. | The output distribution (**OUTPUT DIST**) section allows the user to alter divide ratios and phase offsets for each output of the [[adi>ad9508|AD9508]]. Each divide and phase block can be edited by typing the preferred value within the block, and then pressing the **ENTER** key. When **ENTER** is pressed, the values are loaded into the evaluation board. The phase offset blocks accept the u (micro), p (pico), and n (nano) prefixes.
