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. the attenuator 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
