I have a question about the power supply of AD9949.
I supply 3.3V to DRVDD and DVDD.
And, I supply 3.0V to HVDD, RGVDD, AVDD and TCVDD.
Is there a problem in this usage of power supply though I supply 3.3V and 3.0V to AD9949?
Forwarding to the right person.
This supply configuration is OK.
Thank you for your reply.
I have another one question.
In the circuit configuration of the AD9949 data sheet( page 30 ) , DVDD and AVDD is connected with the same analog supply.
Should I connect the same power supply with AVDD and DVDD as shown in this circuit configuration?
Connecting AVDD and DVDD together to the same clean supply provides a simple but high performance configuration. You can use a separate supply for DVDD, but be sure it is well filtered from system digital activity and/or supply switching noise.
