PS8559中文资料2-Lane PCIe 8GT/s and SATA 6Gb/s Redriver, Bidirectional数据手册Parade规格书

描述 Description

2-Lane PCIe Gen 3 and SATA Bidirectional Redriver
The PS8559 is a bidirectional, 2-lane signal redriver that supports both PCIe (PCI Express) Gen 3, with data rates up to 8.0 GT/s, and SATA, with rates up to 6 Gb/s.  By supporting both PCIe and SATA it is ideal for SATA Express applications, and by supporting two lanes of PCIe, it is also ideal for M.2 interface applications.  In a typically application the PS8559 is placed close to the PCIe or SATA connector to compensate for board losses and regenerate high-quality electrical signals for improved link reliability.
