nRF52832 external clk source

[mhaggag]

I know from the product specification for the nRF52832 chip that the high frequency clk can use a external 32 MHz crystal as source. My question is, is it possible to supply a direct external 32 MHz clock line instead of having an external 32 MHz crystal as a source to the chip ? is there a different port for it ?

Hi,

This was possible for nRF51, but due to changes in the clock subsystem it is no longer possible.

Best regards,

Øyvind

Is this true for the nRF5340 as well?

Yes.
