SAS and other Serial Protocols for the HDD Industry

LSI offers a complete line of HDD-to-host interface physical layer (PHY) IP for serial standards (SATA, SAS and FC), operating at data rates up to and including 6.0 Gigabit per second. LSI continues to build on years of experience with high-speed serial technology for the HDD market. The innovative and robust designs of our TrueStore® PHYs provide the best performance, lowest power, high-speed data transfers between disk drives and host devices, in addition to supplying flexible and cost-saving feature sets for link diagnostics.

LSI's TrueStore® PHYs set a new benchmark in performance with their superior capability of transmitting exceptionally clean signal to the host and, in turn, being able to receive almost-garbled data and restore it without errors. The ample performance margins shown by these PHYs offer robust operation in the widest variety of host environments, thus enabling HDD makers to reduce costs and focus on system level design.

LSI's TrueStore® PHYs have been developed as part of the LSI total recording system design that includes read channels, preamplifiers, microprocessor cores, and hard disk controller IP that are integrated into LSI's HDD System-on-Chip (SoC) products. The system is designed as a whole to give HDD makers the fastest time to market, highest reliability, increased performance and lowest overall system power.
