Hi ,

DS280MB810ZBL device

We are using DEMUX option for our application.

what will be the hardware configuration and register configuration that we need to take in account in order to make Demux work?
what will be the hardware configuration and register configuration if we will use w.r.t pin mode ?
what will be the hardware configuration and register configuration if we will use w.r.t SMBus ?( as we need both straight and crosss point )
Is the schematics attached correct or do we need to make changes suggest ?

Hi Shweta,

I believe one of your colleagues already requested a schematic review. Please see below:

To use MUX pin control, you will need to enable pin control using shared register 0x5[1] of both quads. Please see below for MUX pin control details.

To use SMBus, please review section "Select Crosspoint Mode" of the programming guide, found in the secure resource folder: https://www.ti.com/drr/opn/DS280MB810-DESIGN

Thanks,

Drew
