WHITE PAPER



Sharing crystal with a MCU

1. Preface

This white paper gives guidelines on how a crystal can be shared between an nRF transceiver
from Nordic Semiconductor and an external micro controller unit (MCU). The nRF24L01 has
been used as an example in this paper, and all data have also been taken from the datasheet of
this device. In case other nRF devices are to be used, all necessary data can be found in the
corresponding datasheet.


2. Crystal from MCU used to feed nRF24L01

In this setup the MCU controls the startup of crystal, feed the clock to nRF device, and also
specify most of the crystal requirements. This is the recommended setup, due to the
advantages listed at the end of this chapter.
