SN65DSI84-Q1: Is Initialization Sequence strictly required under any condition?

Part Number: SN65DSI84-Q1

Hi, team,

My customer used SN65DSI84-Q1 as DSI-LVDS bridge.

The chip works well in the first initial system power up. While at one time they set chip into sleep mode and cut off Vcc power, but DSI signal is still present. After this when wake up the chip and power on Vcc, the chip will not work normally.

So the question is, is Initialization Sequence strictly required under any condition when Vcc is power on?

Thanks.

Johnny
