CC2652RB: RCOSC_LF can be calibrated by 48MHz BAW?

Hisao Uchikoshi

Part Number: CC2652RB

Hi Experts,

Does CC2652RB support RCOSC_LF calibration by SDK as same as current CC265x? I want to know whether CC2652RB can support both 48MHz and 32KHz external crystal-less for BLE application.

Regards,

Hi,

Yes, CC2652RB supports total crystal-less operation without any external crystals!

You can run BLE without the 32 kHz crystal by following this application report: www.ti.com/.../SWRA499 or you can derive the LF clock from the HF clock. See this application report for all the details: www.ti.com/.../swra649
