What is the recommendation for unused OSC_CLKOUT outputs?

Should they be left floating or terminated?

Thanks,

Hello Lauri,

Very sorry for the delay, I had responded last week but I guess it failed to post.

These can be left floating if unused.

Adrian

Dear Adrian,

Thanks for the quick response. Are these outputs always transmitting?

Thanks,

Hello Lauri,

Yes, by default it is enabled on power on. Please refer to 'oscclkout_dis' bit of the AWR_CHAN_CONF_SET_SB sub block in the attached Radar Interface Control Document.
