Connecting Multiple ESP32 on the same ref clock and wifi signal

[reig4s]

Hey guys, i’m trying to connect 9 esp32s to the same 40 MHz reference clock so they all run in sync. can i just daisy-chain the clock line to all of them, or do i need to use some kind of clock buffer or fanout chip? not sure how much load the oscillator can handle on its own. any advice would be super helpful!

also i’m trying to feed a wifi phase reference signal through a coax cable from one input to multiple esp32s. do i need to use a resistive splitter, rf power splitter, or something else to safely split the signal without messing up impedance? just not sure what the best way is to distribute that rf signal cleanly to all devices. any tips?
