| | ==== Setting up AD9208/AD9699 Fsx4 Mode ==== |
| | Fsx4 mode on AD9208/AD9699 is only supported using [[adi>en/content/CU_High-Speed_ADC_FIFO_evaluation_tools/fca.html#ADS8-V1|ADS8-V1]]. The procedure below shows how to use Fsx4 mode with ADC sampling frequency of 3GHz and a Reference clock of 600MHz. |
| | - On the Chip Application Mode tab, click on the Fsx4 Operation dropdown menu and select "L/M = 4/1" for AD9699, "L/M = 8/2" for AD9208. <WRAP>{{ :resources:eval:fsx4_mode.jpg?direct&600 |}}</WRAP><WRAP centeralign>//Figure 31. AD9699 Fsx4 mode setting//</WRAP> |
| | - Source the required REFCLK to the [[adi>en/content/CU_High-Speed_ADC_FIFO_evaluation_tools/fca.html#ADS8-V1|ADS8-V1]]. |
| | - Click Proceed to Analysis. This is ACE's Analysis tool for data from the ADC, displaying both sample plots and FFTs. Click on FFT and run one capture. |
| | - A successful capture is shown below, with a filtered 255 MHz signal input to Channel A. <WRAP>{{ :resources:eval:user-guides:ad9208:stepbystep:15.png?direct&500 |}}</WRAP><WRAP centeralign>//Figure 32. AD9208-3000 Fsx4 FFT at 255MHz Analog Input to Channel A//</WRAP> |
