Product Description

LRNV9F24 is a signal retimer adapter used to secure the link budget to meet the challenging signal integrity requirements for long PCIe Gen4 channel comprising PCB, connector and cable. It uses advanced signal conditioning techniques to compensate for the channel attenuation and remove the impacts of various jitter sources. It connects NVMe SSD or PCIe connectors via SlimSAS connector (SFF-8654).

Applications

It is targeted for meeting the higher performance PCIe Gen4 interconnection needs of the following end applications:

• Servers
• Storage Appliances
• Hardware Accelerators

The Motherboard with CPU and BIOS needs to support bifurcation to ensure PCIe x16 link width to bifurcate two x8 link width or four x4 link width for NVMe SSD, Otherwise this card can only support one PCIe x8 link width.

Features

High Performance Retimer
- Compensate for channel loss up to 30dB by comprising PCB, connector and cable
- Eliminate deterministic and random jitter

PCIe Standards and Compatibility
Supplemental Features and Standard BGA

Clocking
- Use standard 100MHz reference clock
- Supports the optional SRIS feature (Separate Reference Clock Independent Spreading)
- Support 100MHz reference clock output

Directly connected to PCIe 4.0 U.2 NVMe SSD by SFF-8654 8i to 2x SFF-8639 cable

Support bifurcated in quad x4 data link width configuration(CPU and BIOS both support)

Support bifurcated in two x8 data link width configuration (CPU and BIOS both support)

Build in SlimSAS(SFF-8654) 8i connector 2 sets, pin-out defined by SFF-9402 for high-performance storage connectivity

Eight internal lanes per SlimSAS 8i port, 128GB/s per port，

PCIe Standard Full-profile bracket pre-installed and also a low-profile bracket for small form factor computer.

Specifications

PCI Express Base Specification, r4.0, compatible PCIe 1.0&2.0&3.0

Compliant with Intel PCIe 4.0 Retimer

Compliant with SFF-8654 Specification Version 1.2

Compliant with NVM Express 1.3

Support up to 4 NVMe SSDs

Support hot plug,but need to be used with a backplane that supports hot-swappable, Such as Intel whitley Ice Lake server and AMD server backplane & TYAN TS65A-B8036 (B8036T65AV4E24HR)

Operating System support

The adapter does not require a driver for operation or communication to attached NVMe drives. The drives are presented natively to the host and use the native NVMe drivers.
