 This method is referred as **clock distribution**. All lower level clock-chips receive their input clock via ''​FIN''/​CLKIN1 and are synced via ''​RFSYNC''/​CLKIN0. This method is referred as **clock distribution**.

 +<note tip>This mode also allows for TRX baseband rates that would be otherwise not possible with the default installed VCXO of 122.880MHz. Let's say someone needs exactly 250.000MSPS. This becomes possible by providing a 500.000MHz or 1000.000MHz external clock.</​note>​
