Hi

CSTART pins (pinnumbers: 28, 29): I use CONVST pin. In the datasheet it is written to connect
 CSTART to '0' logic. The engineer connected CSTART+ pin to 0 logic through 3.3K pull down and  the
CSTART- pin was left open (NC). Should I connect the CSTART- pin to +VBD
(through 3.3K pullup)?

    Hi Eli,

    Verified with the design team.  Both differential logic inputs need to be driven to create a valid logic level.

    When using CONVST, the user should pull-down the CSTART+ pin to 0 through a pull-down resistor and the CSTART- to +VBD through a pull-up resistor.

    Thanks and Kind Regards,

    Luis
