I am using an external clock and not the internal oscillator, what do I connect Kelvin ground to?

There's a figure in the datasheet illustrating. Basically capacitors that make up the tank circuit of the osc should go to the Kelvin GND without being connected to GND on the PCB.

From the Datasheet, Figure 6-4. I am trying to use option (b) with an External Clock Signal. It doesn't say what to connect Kelvin_GND to for option (b)
