Part Number: TS3DV642

Customer have a follow up question on the pull-up/pull-down resistors populated on the SDA and SCL pins:

"

In our application we have 2 display port connectors.  From the datasheet, the AUX pull-ups and pull-downs are drawn on the connector side.

Can we put them only on the controller side, as shown below?"

    Hi,

    The DisplayPort sink uses the AUX common mode voltage to detect the connection of a powered or un-powered source (graphic and memory controller). When moving the pullup/pulldown to the other side, you lose the sink individual connection detection capability.

    Thanks
