Infineon Technologies AG announced that it has demonstrated functionality and data rates exceeding 3Gbps speed of read channel, setting the pace for next-generation HDD SoC technology. The read/write channel IC is the result of a cooperation between Infineon and Hitachi Global Storage Technologies.

When combined with Infineon's 6Gbps Serdes interface, the read-channel core enables integrated advance SoCs to perform higher transfer ratess. The HDD Read Channel provides exceptional speed and high-performance signal processing required for next-generation perpendicular recording for HDDs in enterprise applications.

"High-channel data rate combined with low-power consumption are key to innovation in the enterprise segment to enable the integration of the read channel into the SoC or to provide reliable, high-quality stand-alone ICs in cost-effective packages," said Peter Bauer, member of the management board and head of Infineon's automotive, industrial and multimarket business group.

The read channel is part of the broad portfolio of Infineon silicon proven products and IP blocks which cover the full spectrum of HDD market segments, including consumer/ultralow power, mobile, desktop and enterprise applications, which reduce customer development costs and time-to-market.

Various versions of the channel core are derived from the common architecture and custom designed to meet specific target parameters for each market segment.

Complementary to the high-performance read channel, Infineon has also demonstrated silicon of its 6Gbps multistandard PHY, capable to operate bit error-free in "closed eye" environments required by the upcoming SAS 6G standard. The multistandard PHY supports 6Gbps SATA and SAS as well as FC 4.25Gbps standards and all their legacy modes. A 3Gbps SATA derivative of the same baseline architecture is specifically tailored to support power sensitive mobile applications.
