AD7746 Wiring Diagram

I looked through the technical data sheet for the AD7745/AD7746 CDC chips. Near the end of the data sheet (page 24 of 28) there is a "typical application diagram" that illustrates how to connect a single variable cap into CIN1(+) and CIN(-).


I'm wondering if I can get an explicit wiring diagram for connecting two variable capacitors to the inputs of the AD7746 chip. Specifically, I'd like to know how each pin of the chip should be connected to the capacitors, power supplies, etc. before I send out my design for a custom flex circuit.
