Remove LF clock from nRF52832

JIYEON

Hello,

Currently In customized PCB board, nRF52832 is connected to both HFCLK(32MHz) and LFCLK(32MHz).

It takes up too much space. So HW engineer asked me to consider remove LFCLK.

Is it possible to remove LFCLK?

Our project is based on ESB example. And It use SPI communication, sleep/wake-up function.

    It should not be a problem to use the internal LFCLK RC oscillator instead of the external LFCLK crystal. Though the tolerance of the internal is typically up to 500ppm, so you may need to consider the extra drift when using the internal (e.g. drift up to 500us in 1second) vs. the external (e.g. drift up to 20us in 1 second).
