TIDA-00425

Design files

Overview

This reference design extends the link distance and loss budget of high speed SAS-3 data paths, using configurable equalization, de-emphasis, and output voltage. It supports SAS and SATA interfaces from 1.5 Gbps to 12 Gbps using a miniSAS-HD interface.

Features
  • 4x Lane SAS-3 design compatible to an external miniSAS-HD connector.
  • Easily integrates to existing SAS environments with no additional software.
  • Facilitates the use of common FR4 and other low-cost interconnect materials.
  • Improve Signal Integrity and system rubustness
  • Compatible with link training between host and storage system components.
  • Compatible with OOB signaling in SAS/SATA systems
