Introduction

NS1068/NS1068X is a versatile high-performance and low power USB 3.0 to SATA bridge controller. On one side, it interfaces with the USB interface and is compatible with USB SuperSpeed (5Gbps), Hi-Speed (480Mbps), and Full-Speed (12Mbps). On the other side, it interfaces with hard drive or SSD devices through the SATA interface. NS1068 and NS1068X are pin-to-pin compatible. NS1068 supports SATA I (1.5Gbps) and SATAII (3Gbps). NS1068X also supports SATA III (6Gbps).
