All the parameters are specified between 1V and 6V of Tuning Voltage
Remark :
The minimum and maximum values take into account the spread due to the operating temperature
and process spread.
These performance has been obtained with the chip in QFN package assembled on the
recommended boards (ref. 96348 B) described in this document. These performances are highly
dependent on this environment.
