14.3.8 TCXO connection

It is possible to use an external TCXO instead of a crystal.

This option does not require production line trimming, but it will draw more current and hence

significantly degrade sleep performance. The TCXO should be disabled when in Shutdown mode to reduce

current consumption. It is not possible to dynamically control the TCXO when transitioning between Sleep

and Active states. The TCXO should have a typical clipped sine wave output of 0.4 V peak (maximum 0.6 V

peak) and be connected through a series capacitor (typically 10 nF).
