Note: Power-Up with LE= 1 provides direct parallel operation with

B4-B0.

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 B4-B0 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
