Innocard DP9504 Gen-Z 1C to PCIe x4 Gen4 gender changer

SKU CH-5DAT-964TZ

Converts a Gen-Z 1C EDSFF SSD to a PCIe 4.0 x4 slot with integrated ReDriver and signal buffers for extended reach

  • Changer TypePCIe Gen4
  • Converts Gen-Z 1C EDSFF to PCIe 4.0 x4 for high-speed storage
  • Built-in ReDriver extends 16 GT/s signals over longer traces and cables
  • Integrated clock buffer and SMBus repeaters maintain signal integrity across distance
  • Hot-swap control via SMBus I/O expander at address 41
  • Compliant with SFF-TA-1002 1.3 and SFF-TA-1009 2.0 specifications

Gen-Z 1C to PCIe x4 Gen4 adapter

The Innocard DP9504 converts a Gen-Z 1C EDSFF solid-state drive to a standard PCI Express 4.0 x4 add-in card slot. It integrates a PCIe ReDriver and clock buffer to maintain 16 GT/s signal integrity over longer traces. An SMBus I/O expander at address 0x41 handles power-disable and reset control for the EDSFF device. The card is designed and manufactured in Taiwan.

Replaces direct Gen-Z backplane connection

This adapter lets you install an EDSFF 1C Gen-Z SSD into a conventional PCIe x4 Gen4 slot when a native Gen-Z backplane is unavailable. The jump is worth it when you need to validate or deploy E1.S 5.9 mm drives in a standard server or workstation chassis. Built-in PERST#, WAKE#, CLKREQ# and PWRBRK# buffers preserve side-band signalling across the longer electrical path. Compliance with SFF-TA-1002 v1.3 and SFF-TA-1009 v2.0 ensures mechanical and electrical interoperability.

Fits a PCIe x4 Gen4 slot with hot-swap support

The card occupies a single PCIe x4 Gen4 expansion slot and provides a latched EDSFF 1C connector for the drive. On-board ReDriver and 100 MHz clock buffer extend reach for flexible cable routing inside the chassis. SMBus buffers and the I/O expander enable hot-swap power and reset management without additional host circuitry. The assembly supports the E1.S 5.9 mm form factor and follows the PCI Express Base Specification Rev 4.0 and PCIe CEM spec R4.0.

Questions about this item

What PCIe slot width and generation does the DP9504 need to operate?

The adapter requires a PCI Express 4.0 x4 slot to deliver 16 GT/s differential pair signals through its built-in ReDriver.

Which step is most often missed when inserting the EDSFF 1C SSD into the on-board latch connector?

The latch must be fully engaged until it clicks, otherwise the SMBUS I/O expander at address 0x41 cannot assert PWRDIS and SMBRST# control.

What specification revisions should be checked when the SSD is replaced after extended use?

Verify the new drive complies with SFF-TA-1002 revision 1.3 and SFF-TA-1009 revision 2.0, and matches the 5.9 mm E1.S height.
