[ DS90UB964-Q1 ] Reset After Power-On

Hi,

For DS90UB914A-Q1, it's suggested to perform reset, if FPD-Link is not initialized in the correct sequence.
Is this necessary for DS90UB964-Q1?


(Quote from DS90UB914A-Q1 datasheet)


It's supposed to have 4 cameras for DS90UB964-Q1 type of device. If one camera out of 4 fails to initialize correctly or loses LOCK, is is recommended to perform reset with either PDB or register?

Thank you for your support in advance.
Regards,
Ken

    Hello,

    There is no need to hard reset the DS90ux96x devices when a single sensor connected to one of the four Rx inputs does not configure properly. You could perform digital reset without registers, but first try :
    Disabling port forwarding for the Rx port X in question
    Reset imager on port X,
    configure image sensor on port X.
    apply AEQ_RESTART in register 0xD2[3] (After correct input signal frequency to 96x Rx port X )
    Enable port forwarding on Rx port X (After lock status verified)
