We have a customer asking whether does the QN9021 chip need calibration for trimming crystal.

We obtained the QN9000 Calibration manual (as per attached) and in the manual stated, the 3rd party software tool (XCSEL) is needed to purchase for the calibration of trimming crystal.


We would like to double confirm with NXP, whether is this calibration necessary before our customer goes ahead and purchase the 3rd party tool.
