I made the hardware like this to test it in the most empty state. There is only a cap connected to the AINO pin. I removed the 22 ohm resistor. I removed the resistor on the mod out output. It is empty now. I removed the resistor on the RX_IN pin. It is empty now. REF_GND is connected to Ground. REF_EN, PVDD, IOVDD are connected to 3.3V. RX_INF is connected to ground with 560 pf. I still see VDD=1.798V and VREFIO=1.798 V. Are these test conditions correct? I tried to isolate it from the rest of the circuit.
