Hard Drive Physical Layer interface IP modules

First to support the new 6Gb / s SATA (Serial Advanced Technology Attachment) hard drives to connect standard MIPHY (physical layer multi-standard interface) Physical Layer interface. Physical layer macrocell from and sent to the hard drive of data reconciliation in the implementation of high-speed serial serial conversion functions, and to provide a data link layer for connecting the 20-bit wide parallel interface. SATA is the most popular hard disk drive (HDD) interface, SATA International Organization (SATA-IO), held in San Francisco Intel Developer Forum (IDF) published a new interface standard, the new standards, the maximum data transfer rate from 3Gb / s to 6Gb / s, ST displayed at the same time new products. ST's 6Gb / s SATA PHY is an IP (intellectual assets) modules, together with other functional modules into low-power 1.5Gb / s, 3Gb / s and 6Gb / s SATA hard disk drive system-on-chip (SoC) on. ST display module contains the SATA physical layer physical layer serial interface, using 65nm CMOS process. The leadership of a well-known hard drive manufacturers in the second half of this year's new products using the technology. "With consumers more and more hard disk storage of music, video and photographs, and other multimedia files, they need a faster hard drive data transfer rate," ST Data Storage Products Division, said Vittorio Peduto, General Manager, "ST and SATA International organization has maintained close cooperative relations, so that we can guarantee for the first time the hard disk manufacturers provide certification authority solution. " ST's 65nm MIPHY IP module in the previous generation based on 90nm technology has made great leaps and bounds. MIPHY new modules to the hard drive manufacturers to bring greater economic value of new products to reduce die size by 35%, 30% lower power consumption. In a balanced circuit and the transceiver circuit, the structure after further improved markedly enhanced anti-jitter performance, send reduced-jitter phenomenon. These advantages for the mobile hard disk drive market and cost-sensitive PC desktop hard drive market is particularly important, because in these two systems on the market makers in particular need to provide high-performance low-power products to differentiate it from its competitors.
