Tool/software:
I wish to use LMK04832EVM in single loop mode, where a single-ended clock source is input into the OSCin port.
The EVM user guide says "An external VCXO may be optionally attached through these SMA connectors with minor modification to the components going to the OSCin/OSCin* pins of device." However, I did not see any details on what component modifications are required to use the EVM in single loop mode.
What component modifications are required to enable this configuration?
Hi Colby
Refer to following: 
So for the most part you need to remove power from the VCXO which can be done by removing FB12, but you also need to remove power from the LDO powering the VCXO which can be done by removing R238. Failure to remove R238 can result in the ESD protection circuit triggering and suddenly you power supply is drawing 6A of current assuming you don't have current protection enabled.
After this you can remove R69 (0Ohm jumper for VCXO output) and place it on R72 pad so the SMA connector signal path can be complete.
There are a variety of terminations depending on what ref clk source you're using: 
If you're utilizing a Sine Wave from a signal generator any other source that expects a 50Ohm load, then you would need to remove C20 & C23 & place a 50Ohm to GND resistor on R70.
The main thing is disconnecting power from the VCXO and the LDO powering the VCXO.
After this it's just ensuring you're have the correct termination for whatever reference clock type you're using.
Best regards,
