| ==== 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 100 Ω and ac-coupled into the [[adi>AD9508|AD9508]] reference inputs. An amplitude setting of 0 dBm to 6 dBm is fine. The CLKIN_B 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 0 Ω. Connect an oscilloscope, spectrum analyzer, or other lab equipment to any of the J209 to J216 SMA clock OUTx connectors on the edge of the board. OUT0 through OUT3 are ac-coupled outputs differentially terminated to 100 Ω. | To connect signals, connect a signal generator to the J200 (CLKIN) SMA connector.

I<sup>2</sup>C 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 [[adi>AD9508|AD9508]] outputs. Using the Sx pins to program the part gives the user limited control of each channel divider ratio and no control of phase offset.

| ==== Output Distribution ==== | ==== Output Distribution ==== |
| 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. 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 automatically rounds 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]].
