Innocard M.2 PCIe Gen 4 gender changer with ReDriver for SFF-TA-1002, SFF-TA-1020

SKU CH-30ZN-4XH3Y

Converts Gen-Z 1C EDSFF devices to PCIe 4.0 M.2 using a built-in ReDriver and clock buffer for 16 GT/s signal integrity over longer cables

  • Adapter typePCIe Gen4
  • Converts Gen-Z 1C EDSFF to PCIe 4.0 M.2 4-lane
  • Built-in PCIe ReDriver extends 16GT/s signals over longer traces
  • On-board 100MHz clock buffer drives extended cable lengths
  • SMBCLK/SMBDAT bidirectional repeater maintains link integrity
  • PERST# bus buffer gate supports longer trace and cable runs

Gen-Z 1C to M.2 PCIe 4.0 adapter

This adapter converts a Gen-Z 1C EDSFF connector to a four-lane PCI Express 4.0 M.2 slot. An onboard ReDriver extends 16 GT/s differential signals while a clock buffer and SMBus repeater maintain link integrity over longer traces. PERST# buffering supports extended cable runs in server and accelerator chassis.

Suits rack, tower and microserver builds

Engineers adding Gen-Z storage or accelerator cards to platforms with M.2 sockets will find the mechanical and electrical conversion handled in one module. Systems without a Gen-Z 1C edge connector or without space for the adapter length cannot use this part.

PCIe 4.0 ReDriver for 16 GT/s operation

The integrated ReDriver is the component that enables Gen 4 signal quality across the gender change. Without it, the 16 GT/s link would not meet the PCI Express Base Specification Rev 4.0 eye requirements over the combined connector and trace path.

Questions about this item

What PCIe generation and signalling rate does the SFF-TA-1002/1020 gender changer support?

It complies with PCI Express Base Specification Rev 4.0 and the built-in ReDriver extends 16GT/s differential-pair signals across the Gen-Z 1C to M.2 conversion.

Which connectors and physical standards must the host and device match for this adapter to fit?

The adapter has a built-in Gen-Z 1C (EDSFF) connector on one side and converts to a PCIe 4.0 M.2 4-lane slot compliant with the M.2 Spec Rev 4.0 Ver 1.0.

What firmware or BIOS requirement is often missed when installing this gender changer in a server or desktop?

The system must run UEFI 2.3.1 or later; legacy BIOS without UEFI support will not initialise the PERST# and SMBus buffers correctly.
