Hi,

As titled, I want to double confirm that "does a second time PDB reset needed in 947's initialization?" if no, I will let customer remove that.

and no matter how many times 947 reset, the 948 need to power up after the 947 sending out valid video data， right?

thank you

B&R

    Hi Yuan, 

    Can you be more clear about when the second PDB reset is happening during the 947 initialization sequence? 

    Yes, it is recommend for the deserializer to be powered up once there is valid video data as per the power up sequence section of the 948 datasheet. 

    Best,

    Shu
