AM5718: SYS_CLKIN2 Purpose

Part Number:AM5718

Hello,

I have a custom AM5718 board with both OSC0 (for SYS_CLKIN1) and OSC1 (for SYS_CLKIN2) populated, similar to  AM57x8 EVM.

I want to remove OSC1 in the next revision since it's listed as optional in the datasheet, so I tried disabling it, and, as far as I can tell, everything still works.

Is there a reason why OSC1(SYS_CLKIN2) would be needed?

I found an answer to a similar question pointing to chapter 3 of the TRM. I looked there and OSC1 is listed as optional, but I could not find any mention of a case where OSC1 is needed.

In other words, is there any functionality which requires OSC1/SYS_CLKIN2?

Thank you,
