https://community.nxp.com/t5/i-MX-Processors/i-MX8-ULP-Clock-Input/m-p/1933261#M227346 <P>Hello everyone,</P><P>I'd like to use the i.MX 8ULP with a single-ended buffered clock source instead of a crystal oscillator. Does the input structure of EXTAL32 and EXTAL0 on the i.MX 8ULP in the WLCSP package allow an externally generated clock signal to be used? If so, which of the two pins should I use?</P><P>Thank you very much!</P> Fri, 16 Aug 2024 00:00:15 GMT Lukas_LH 2024-08-16T00:00:15Z https://community.nxp.com/t5/i-MX-Processors/i-MX8-ULP-Clock-Input/m-p/1933261#M227346 <P>Hello everyone,</P><P>I'd like to use the i.MX 8ULP with a single-ended buffered clock source instead of a crystal oscillator.
