a. The BCM43907 is functional across this range of voltages. Optimal RF performance specified in the data sheet,
however, is guaranteed only for 3V < VBAT < 4.8V.
b. VDD3P3RF, which is an internally generated supply, can drive this node. There is sufficient current and the
appropriate state is maintained during hibernation and sleep cycles.
c. Internally generated supply.
d. Programmable 2 mA to 16 mA drive strength. Default is 10 mA.
