1 DS320-SLIMSAS-EVM Evaluation Module (EVM)
The DS320-SLIMSAS-EVM together with the DS320PR810-RSC-EVM, or other Texas Instrument's riser-card style PCI-Express™ 5.0 redriver evaluation module, provides a complete high-bandwidth platform for evaluating the signal conditioning features of the Texas Instruments PCI-Express 5.0 linear redrivers. These evaluation boards can be used for performance evaluation and initial system prototyping.

1 Introduction
DS320-SLIMSAS-EVM is a PCI-Express 5.0 x16 to two x8 SlimSAS (SFF-8654) adapter, which enables DS320PR810-RSC-EVM and other Texas Instruments PCI-Express 5.0 redriver riser card evaluation modules to interface with up to four U.2 solid state drives (SSDs) using commercially available SlimSAS (SFF-8654) to U.2 (SFF-8639) cable assemblies (not included). Interface to M.2 SSDs is also possible using commercially available U.2 to M.2 adapter cards (not included).
DS320-SLIMSAS-EVM features Texas instruments LMK00334 PCI-Express clock buffer for distributing the PCI-Express 100 MHz reference clock to downstream SSDs. It also allows flexible assignment of the PCI-Express side band signals using jumpers.
