2.1.7
Separate supplies of 1.8 V (1.75…2.0V) and 1.4 V (1.4…3.6V)
The dual 1.8V and 1.4V power supply the most efficient configuration to run u-blox 6 receivers (see section
2.1.3 for details). It assures stability since the sensitive RF supply is well separated from the fluctuating base band
power supply.
