Do not share GND_XOADC_ISO with other gounds.
connect to GND_XOADC on Pin #109
through dedicated via to GND plane.
PIN #1,13 must be connected to main GND using dedicated via
C4124 close to X4100 and connect cap GND
Route GND_XOADC as trace to GND plane at one location only.
Do not share GND_XOADC with other gounds.
Do not share GND_XO and GND_RFCLK
Odd number MPPs can be configured as analog output voltage buffers
Even number MPPs can be configured as current sinks,
