Hi Moto-san, Indeed, it looks like the AD9228 DRVDD supplies power only to the LVDS related circuits. Bringing DRVDD down-then-up should not affect register contents, but to be safe it would seem good...

To be safe, I would use a 100mA to 500mA schottky diode. That way the schokkty will conduct well before the body diode of the LDO
