LSI announces next-generation preamplifiers delivering higher performance and lower power for hard disk drives

New preamps serve notebook, desktop and enterprise HDD markets, lowering power and accelerating time-to-market for HDD manufacturers.


Date: 17 Nov 2011

LSI has announced the TrueStore® PA5100 and PA5200, the company’s latest high-performance, low-power preamplifier integrated circuits (IC) for the notebook, desktop and enterprise hard disk drive (HDD) market segments.

The PA5100 and PA5200 preamplifiers deliver operating speeds of up to 5.0Gb/s, a 25 per cent performance improvement compared to the previous-generation, and consume significantly less power than its predecessor. The PA5200 write driver uses a conventional dual power design, and can deliver more than a 15 per cent reduction in preamp write power. The PA5100 write driver operates from a single power supply, which can enable a preamp power reduction of more than 35 per cent for next-generation HDDs.

The new preamplifiers provide hard drive manufacturers with the flexibility to deploy a common IC capable of serving all major HDD market segments – from 5.4K RPM notebook through 15K RPM enterprise HDDs. Hard drive makers who integrate PA5100/PA5200 preamps into its drive assemblies can benefit from lower development costs, reduced inventories and an accelerated time-to-market with a single preamp capable of addressing a wide range of application requirements.

“HDD manufacturers rely on LSI to deliver world-class HDD silicon technologies that raise the bar for hard drive capacity, power and performance,” said Phil Brace, senior vice president and general manager, Storage Peripherals Division, LSI. “With operating speeds up to 5.0Gb/s, the new preamps provide HDD makers with high-performance solutions that easily surpass end users’ data rate requirements while offering optimal power-performance balance.”

The LSI TrueStore storage IC product portfolio provides a complete head-to-host recording system design, including preamplifiers, read channels, serial PHYs and ARM® core processor IP. By optimising the entire system data path, the TrueStore family enables HDD makers to continually develop higher-capacity products with increased performance and lower overall power usage, while enabling faster time-to-volume and lower costs.

By offering a broad portfolio of SoC and preamplifier solutions, LSI enables its HDD customers to address all segments of the storage market, from mission-critical enterprise applications and high-capacity desktop PCs to low-power laptops and tape archive solutions.
