Re: OCXO as a Clock Source
Finally got a 26MHz OCXO in my hands \o/ I want to remove the 26MHz Xtal of my ESP32-Thing and feed the ESP with the clock signal from the OCXO. However, I seem to be unable to find specific information in the datasheet or hardware design guide on how to operate the ESP32 with an external oscillator...

Re: PDM low-pass filter design
I'm also interested in this. I guess one needs a higher order filter, RLC or so. I've tried with some 220µH inductor in series and its a little better. I'd be interested how such a filter is calculated. A proper approach for Class-D amps seems to be something like this: http://www.ti.com/lit/an/sloa...

Re: OCXO as a Clock Source
Thanks!
So I should opt for a 40, 26 or 24 MHz OCXO

OCXO as a Clock Source
Hi,
as far as I've understood, Wifi and BT will only work with the default (40MHz?) clock frequency.
If I'm ok without Wifi and BT, can I simply connect a 10MHz OCXO as a external clock source to a ESP32?
Thanks
