Converts Gen-Z 1C EDSFF to PCIe 4.0 x4
This Innocard DP9504 Rev1.1 adapter converts a Gen-Z 1C EDSFF device to a PCI Express 4.0 x4 interface. It supports EDSFF 1C E1.S 5.9mm height SSDs with a built-in latch connector. The green PCB carries integrated signal conditioning for Gen 4 speeds.
Fits a PCIe x4 slot and drives longer traces
The card plugs into a standard PCIe x4 slot and provides a ReDriver, clock buffer and multiple bus buffer gates for PERST#, WAKE#, CLKREQ# and PWRBRK#. These buffers extend 16 GT/s differential signals and 100 MHz clock over longer trace lengths and cables. An SMBus I/O expander at address 41 handles PWRDIS and SMBRST# control.
Replaces a direct EDSFF backplane connection
Use this when the host system lacks a native EDSFF 1C connector but has a free PCIe x4 Gen 4 slot. It adds hot-plug support and signal integrity for cable lengths that a direct backplane trace cannot cover. Not for builders who need a second card or a different EDSFF form factor.

Questions about this item
What signal integrity limit appears first when running the PCIe 4.0 x4 link at 16 GT/s over long traces?
The on-board ReDriver extends the 16 GT/s differential pairs, while the 100 MHz clock buffer and PERST#, WAKE#, CLKREQ# and PWRBRK# gate buffers each push the electrical limit further for sustained high-speed operation.
How much extra heat or power does the adapter add when it stays powered all day?
The board draws only the small current needed for its ReDriver, clock buffer, SMBus expanders at address 0x41 and bus gate logic; no active cooling is required.
Which host-side connector and slot width must the system already provide?
A PCI Express 4.0 x4 slot is required on the host side to mate with the adapter's gold-finger edge connector.
