| | <note tip>For your reference on what frequencies to include in the section, you can download the **HMCAD15xx-Interleaving Spurs Calculator** in the [[/resources/eval/hmcad15xx#helpful_files|Helpful Files]], and input both the sampling and input frequencies on the yellow boxes provided. The calculator will provide the spur frequencies depending on the selected mode.</note> |

| | - When using external clock, decrease the sampling frequency of HMCAD1511 less than the Fsmax of 250MHz/500MHz/1000MHz for quad/dual/single mode. |
| | - When using on-board clock, adjust the clock divider making the sampling frequency of HMCAD1511 less than the fsmax of 250MHz/500MHz/1000MHz for quad/dual/single mode. |
