Tool/software:
Hello,
I have some questions for power up/down sequence of AFE5818.
1)
The recommended power seqeunce on the datasheet is DVDD_1P2 first.
After rising DVDD_1P2, isn't any specific sequce for all other rails reqruied?
2)
The datasheet says that DVDD_1P2 must rise before AVDD_1P8.
Does it menas all other rails, can DVDD_1P8, AVDD3P3, AVDD_5V rise before both DVDD_1P2 and AVDD_1P8?
Or DVDD_1P2 have to be the 1st in any situation?
3)
The datasheet doesn't metion anything power down.
DVDD_1P2 must be last? Or DVDD_1P2 must be after AVDD_1P8 and other rails are don't care?
Regards,
Oba
