So I have 2 stereo out and 2 stereo in.</SPAN><BR /><SPAN>Currently one CODEC is connected to I2S0 clock signals and the other one is connected to I2S1 clock signals.</SPAN><BR /><BR /><SPAN>I declared I2S0 and I2S1 as master (they provide the clocks to the codecs).</SPAN><BR /><BR /><SPAN>How can I make sure that I2S0 and I2S1 clocks are fully in synch ?</SPAN><BR /><SPAN>Do I need to declare I2S1 as a slave interface and feed some I2S0 clocks into the I2S1 ones ?</SPAN><BR /><SPAN>Or is there any internal LPC settings that will guarantee this synchronization ?</SPAN><BR /><BR /><SPAN>Thanks.</SPAN><BR /><BR /><SPAN>Vincent</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:17:20 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1820-and-I2S-interfaces/m-p/528528#M9634 lpcware 2016-06-15T18:17:20Z Re: LPC1820 and I2S interfaces https://community.nxp.com/t5/LPC-Microcontrollers/LPC1820-and-I2S-interfaces/m-p/528529#M9635 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by bavarian on Fri Sep 26 04:42:21 MST 2014</STRONG><BR /><SPAN>Well, the concept to configure one as master, providing the clock to the other block which is configured as slave should do the job.</SPAN><BR /><SPAN>There is no built-in mechanism between I2S0 and I2S1 for getting a phase synchronous operation.</SPAN><BR /><BR /><SPAN>Regards,</SPAN><BR /><SPAN>NXP Support Team.</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:17:21 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1820-and-I2S-interfaces/m-p/528529#M9635 lpcware 2016-06-15T18:17:21Z
