Hello Team

We are using the DS280MB810 linear repeater for straight-thru and demux application. In which we have designed in default pin-mode configuration for straight-Thru and optional configuration through External EEPROM.

Please find the attached schematics and kindly review it and let us know any design changes required for demux application and for SMBUS master mode configuration.

Hi Kowsalyaa,

We're reviewing this and will get back to you shortly.

Not sure if you're planning to use this in your design, but wanted to let you know that pin mode control of the MUX cannot be enabled via just EEPROM configuration on the DS280MB810.

Thanks,
Drew

Hi Kowsalyaa,

Please find our schematic feedback attached.

Regarding cross-point configuration, if you wish to use MUXSEL pins, you will need to enable MUX pin control via a register write.

After this, please reference the diagram below to configure the cross point accordingly.

Thanks,

Drew
