PCIe 4.0 x4 adapter with ReDriver converts to Mini SAS HD SFF-8673 for extended cable runs and server BMC management
- Changer TypePCIe Gen4
- PCIe 4.0 signal reach extended by integrated ReDriver
- Server BMC management supported through PERST# and SMBus
- Industrial temperature range suits harsh environments
- Mini SAS HD 4X to PCIe x4 conversion
- Status LEDs show PERST#, WAKE#, CLKREQ# and ready state
PCIe Gen4 ReDriver adapter
This Innocard add-in card converts a PCI Express x4 Gen4 slot to a Mini SAS HD SFF-8673 4X interface. An on-board ReDriver extends 16 GT/s differential signals across longer cables. Integrated clock buffer, SMBus switch and I/O expander manage link training and power-disable control.
Suited for server BMC management
The card supports out-of-band management through PERST#, WAKE# and CLKREQ# translators with status LEDs. Industrial temperature rating fits harsh environments. Buyers who need internal drive bays or a different connector type should look at other solutions.
Mini SAS HD SFF-8673 4X interface
The single specification that decides fit is the Mini SAS HD SFF-8673 4X connector on a PCIe x4 Gen4 electrical link. Verify your backplane or cable uses this exact interface before ordering.

Questions about this item
How far can the built-in ReDriver extend a PCIe 4.0 signal?
The ReDriver extends PCIe 4.0 16 GT/s differential pair signals and provides programmable linear equalisation, output swing and flat gain.
What thermal load does the on-board clock buffer add during continuous operation?
The integrated 100 MHz clock buffer drives longer traces and cables without active cooling, so it adds minimal thermal load to the system.
Which management interfaces must the host platform expose for the card to function?
The card requires an SMBus for the switch at address 0x71, the I/O expander at 0x20 for PWRDIS control, and the clock buffer at 0x6C.
