Connect an appropriate 10nF power supply bypass capacitor as close as possible
All other pads on the bottom shall not be connected.
These are internally connected for the TCXO compensation process
All connection points in the designated region have solder mask cover to avoid any electrical connections

A ground plane under the device
Do not route large transient signals (both current and voltage) under the device
Do not place near a large magnetic field such as a high frequency switching power supply
Do not place near piezoelectric buzzers or mechanical fans
Minimize air flow across the device
