Tuning the 16 MHz crystal

4.13

The accuracy of the 16 MHz crystal (±10ppm) guarantees the ‘in spec’ operation of the QFN48

antenna module. However, further trimming of the 16 MHz crystal is possible using the procedure

that is described in AN-B-020 End product testing and programming guidelines. See Ref.[2].

Software

4.14

The standard SDK release software, without modifications, can be used for testing or operating the

QFN48 antenna module.

Test platform

4.15

An interposer (078-46-A) was built for hardware interfacing the Expert DK Motherboard (580-MB-vC2

/ 078-10-C2) to the QFN48 antenna module. The interposer can be used as a stand-alone platform,

as it has a debug port (J39). The debug port consist of JTAG, UART, VPP, VBAT and GND signals.
