New hard disk drive read channel IC from LSI

LSI is sampling RC9500, a read channel IC for Hard Disk Drive (HDD) manufacturers. The RC9500 features low-density parity check (LDPC) iterative decoding technology for a 10 percent increase in the data storage capacity of HDDs with data rates exceeding 4.0Gb/s.

The other benefits of RC9500 include improvements in signal-to-noise ratio (SNR), and less firmware complexity.

The RC9500 is manufactured using 40nm process technology resulting in low current consumption in sleep mode.

Analyst/executive comments:

"HDD read channel technology is critically important in a disk drive," said John Rydning, IDC's HDD research director. "Improved read channels made by companies like LSI enable higher capacity disk drives that consume less power. The new LSITM read channel, based on 40nm semiconductor process technology and using LDPC iterative decoding technology, will enable HDD OEMs to reach next-generation HDD capacity points."


"The TrueStore RC9500 is built on a revolutionary new architecture and is part of a total recording system design that includes the LSI preamplifier, customer interconnects, heads and media as part of the complete data path solution," said Phil Brace, senior vice president and general manager, Storage Peripherals Division, LSI. "No other company can offer the breadth of high-performance storage IC products and systems that LSI delivers."
