I2S clock speed using NRF52832 and SGTL5000https://devzone.nordicsemi.com/f/nordic-q-a/74662/i2s-clock-speed-using-nrf52832-and-sgtl5000Hello. I&#39;m designing a board with NRF52832 connected to SGTL5000 via I2S. I&#39;m planning to use the driver found in the Nordic Playground here... https://github.com/NordicPlayground/nRF52-teensy-sgtl5000-audio The documentation mentions the followingen-USTelligent Community 13Mon, 03 May 2021 11:54:59 GMTRE: I2S clock speed using NRF52832 and SGTL5000https://devzone.nordicsemi.com/thread/307900?ContentTypeID=1Mon, 03 May 2021 11:54:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d063fa74-7439-4b40-86e2-acf9fc0546dfKenneth<p><span>You are right, from the I2S timing specification in the PS the MCK frequency(fMCK) is set to max 4000 kHz. You can set the MCKFREQ to a higher value than this by using a divisor that is 6, 5, 4, 3, or 2. But you will then be outside the specification (it&#39;s not been tested as part of HW verification). For instance the clock duty cycle specified at min 45% and max 55% only applies to MCK frequency up to the specified 4000 kHz limit.</span></p> <p><span>Best regards,<br />Kenneth</span></p> <p><span></span></p><div style="clear:both;"></div>
