I understand there is no power up sequence required for ADV7511W from former thread.
On question brought up from an ADV7511 user.
When he attempted 1.8V DVDD(DVDD, AVDD, PVDD, BGVDD) ON at first then 3.3V DVDD(DVDD_3V) ON after that.
Low votage(around 0.0~0.3V, like attached ppt) observed on 3.3V DVDD(DVDD_3V) line just after the 1.8V DVDD(DVDD, AVDD, PVDD, BGVDD) ON.
The low voltage(around 0.0~0.3V) will be observed if 3.3V DVDD(DVDD_3V) line physically disconnected.
Is this known behaviour? Please advise.
