AD9929
POWER SUPPLY SEQUENCING
The recommended power-up and power-down sequences are
shown in Figure 64 and Figure 65, respectively. As shown, the
VM1 and VM2 voltage level should never exceed the VH1 and
VH2 voltage level during power-up or power-down. Excessive
current results if this requirement is not met due to a PN
junction diode turning on between the VM1/2 and VH supply
pins.
Figure 63 describes the AD9929 AFETG and V-driver supplies
associated with vertical driver outputs.

RECOMMENDED POWER-UP SUPPLY
SEQUENCING
When the AD9929 is powered up, the following power supply
sequence is recommended. Refer to Figure 64.
1.
2.
Caution:
There is a PN junction diode from VM1 and VM2 to VH.
Excessive current occurs if the VM1 and VM2 supply level is
greater than VH1 and VH2 supplies.
RECOMMENDED POWER-DOWN SUPPLY
SEQUENCING
When the AD9929 is powered down, the following power
supply sequence is recommended. Refer to Figure 65.
