LSI Corp. has extended what it claims is the industry's broadest portfolio of SoC components for hard disk drives (HDDs) with the introduction of new read channel and physical layer (PHY) technologies.

The new 65nm LSI TrueStore RC8900 iterative decoding read channel offers industry-leading performance with data transfer rates up to 4.0GHz, a 50 percent increase over the previous product. The new 65nm LSI TrueStore PHY8900 delivers a greater than 20 percent performance increase over the previous generation and offers compatibility with 6Gbit/s SAS and SATA, as well as 4.25G Fibre Channel (FC-PI-2) protocols.

At 4.0GHz, the RC8900 establishes a new industry benchmark for read channel performance. The boost in data transfer rates translates to a significant improvement in areal density for nearline storage applications. The RC8900 also shares a common code set with the RC8800 desktop and RC2500 notebook read channel technologies from LSI, providing customers with quick, low-cost drive integration for a reduced time-to-market.

The new PHY8900 offers HDD manufacturers a 20 percent performance improvement and enhanced signal processing resulting in reduced output jitter for an exceptionally clean signal to the host. Additionally, enhanced receiver performance, with adaptive equalization, allows restores of extremely noisy data without errors. Simplified debugging is also enabled with advanced test features including a firmware-controllable signal analyzer which allows HDD makers to observe, debug and easily clean up signals without requiring expensive test equipment.

The LSI TrueStore family of ICs for hard disk and tape drive components, and custom silicon solutions include highly integrated high-performance storage SoCs, read channels, preamplifiers, serial PHYs, custom ARM core processors and hard disk drive controller IP.
