DS90UB913A reset via FPD link from the DS90UB914A

Is there a way to reset the serializer DS90UB913A via FPD link from the DS90UB914A deserializer using the bidirectional control channel?

The 913 is getting latcheed up somehow.

    Hello Ed,


    There is no way to perform a hard reset on the PDB pin other than manually doing it. Technically, if the customer had some sort of control circuit they could control the PDB pin with a GPIO that was toggled over the back channel and sent from 914A to 913A.

    You can perform a "soft" reset on the 913A, however this will need to be through local I2C access and not remote I2C (aka over the back channel). One can reset both the analog blocks of the chip as well as the digital blocks of the chip separately with register 0x01 on the 913A (image below):
