external reference clock cortex M4

Question asked by olivier bureller on Jul 30, 2018

Hello dear experts,


I would like to use several cortex M4 with a 16Mhz  external oscillator instead of a 16Mhz quartz  in our application in order to distribute the same clock to several cortex M4 chips. We really need the same drift and accuracy in our inter chip communication. Is it possible to use a TCXO at 16Mhz with a specialized clock distribution chip. Are the specifications the same concerning the external reference clock  (max 16Mhz) ? What kind of  care has to be taken in the routing and pcb design ?


Thanks in advance for your help.
