Power-Up States
If LE is set to logic LOW at power-up, the logic state of
PUP1 and PUP2 determines the power-up state of the
part per PUP truth table. If the LE is set to logic HIGH
at power-up, the logic state of D0-D5 determines the
power-up state of the part per truth table. The DVGA
latches in the desired power-up state approximately
200 ms after power-up.
Power-On Sequence
The ideal power-up sequence is: GND, Vdd, digital
inputs, RF inputs. The relative order of the digital
inputs are not important as long as they are powered
after Vdd / GND
