ADXRS290 Satellite BOM

Question asked by Mochi on Jan 19, 2018

My customer purchased "EVAL-ADXRS290Z-M2".
It included the schematic "ADXRS290 Satellite Schmatics.pdf". (rs290 _sat 0.0)
On the satellite board, tapes written "ADXRS290 Z-S2", "1.0" are stretched.

Now, in Schematics, a 47nF capacitor connected to the CP terminal is drawn.
But the data sheet says "Charge Pump Output. Connect a 1μF capacitor (rated for 50V) to this pin."

Unfortunately for us, customers are just perplexed about the behavior of ADXRS290.

They lost guidance on POWER SUPPLY DECOUPLING.
Please tell me the correct BOM and Schematic.


Best regards
