PCIe Gen 3x1 to 2- SATA 6Gb/s Bridge


The JMB582 is a bridge controller between the PCIe host and the storage devices with SATA/AHCI interface. Its upstream port provides a PCIe which data transmission rate for PCIe Gen 3x1 specification. Meanwhile, its downstream port can connect to SATA/AHCI storage devices, such as a solid-state drive (SSD). The data speed of each port for the SATA port can arrive at 6Gb/s.
