Can S130 work with 16MHz Xtal Clk?

Hi, From the doc : infocenter.nordicsemi.com/index.jsp, I found that the HF CLK is 64MHz. My custom board has 16MHz Xtal Clock. Will the softdevice work accurately, timing wise, if 16MHz is used instead of 64MHz? Thanks.

  • That link points to the nRF52 product specification. S130 is for nRF51 which can use a 16MHz crystal, but the HF CLK is only 32MHz. For nRF52 you should use S132 and then you will need a 32MHz crystal and the HF CLK will be 64MHz.

    nRF51:

    • S130
    • 16MHz or 32MHz crystal (you can choose)
    • 32MHz HF CLK

    nRF52:

    • S132
    • 32MHz crystal (16MHz crystal not an option)
    • 64MHz HF CLK
