ESP32-S3 with external oscillator

Postby anees_vp » Fri Jul 19, 2024 1:30 pm

I am designing one board with ESP32-S3 along with an external 40 MHz oscillator, instead of a crystal.

Which should be the input pin on ESP32-S3 for oscillator output, XTAL_P or XTAL_N?

For ESP32-S2 hardware design guidelines, I can read as follows:
If an oscillator is used, its output should be connected to XTAL_P
But no such information is provided for ESP32-S3.
