I'm outputting the 32kHz clock on the XTALOSC_REF_CLK_32K pin. I cannot find this information in any specification, but maybe I've missed it somewhere?</P></BODY></HTML> Mon, 10 Jun 2013 13:23:52 GMT https://community.nxp.com/t5/i-MX-Processors/iMX6-32kHz-clock-output-specifications/m-p/284239#M33238 emil 2013-06-10T13:23:52Z Re: iMX6 32kHz clock output specifications https://community.nxp.com/t5/i-MX-Processors/iMX6-32kHz-clock-output-specifications/m-p/284240#M33239 <HTML><HEAD></HEAD><BODY><P>1) The output clock accuracy will be determined by the accuracy of the crystal used.</P><P>2) Unfortunately, we have no data on the phase noise of the output.
