a. Functional operation is not guaranteed outside these limits, and operation outside these limits for extended
periods can adversely affect long-term reliability of the device.
b. The BCM4319 is functional across this range of voltages. However, optimal RF performance specified in the
datasheet is only guaranteed while VBAT is between 3.0 and 5.25V.
c. With VBAT = 3.0V PALDO output = 3.0 –0.2 (dropout voltage) = 2.8V
d. The supported voltage range applies to all three I/O supplies: VDDIO, VDDIO_SD, and VDDIO_RF.
VDDIO and VDDIO_SD often use 1.8V signaling; however, VDDIO_RF tends to use a higher voltage rail, such
as 3.3V, because this supply rail is used for the BCM4319 RF switch and front-end control lines. RF front-end
components (such as transmit/receive switches) tend to require higher control voltages.
e. For any other VDDO from 1.8V to 3.3V ( 10%), VIH and VIL are specified as VIH = from 0.7 * VDDO to VDDO
and VIL = from 0V to 0.2 * VDDO.
