MUNICH, Germany Infineon claims it has demonstrated functionality and data rates in a read hard disk drive read channel exceeding 3 Gbit/s. The read/write channel IC is a result of a cooperation with Hitachi Global Storage Technologies.
When combined with Infineon's 6Gbit/s serdes interface, the read channel core enables integrated SoC read/write SoCs to perform higher data rates for future hard disk drives. In particular, the device is targeted at next-generation perpendicular recording for hard disk drives in enterprise applications, Infineon said.
Various versions of the channel core are derived from the common architecture and custom designed to meet specific target parameters, Infineon said. Complementary to the read channel, the semiconductor manufacturer also demonstrated silicon of a 6 Gbit/s multistandard PHY, capable to operate bit error free in 'closed eye' environments required by the upcoming SAS 6G standard.
While the IC at hand was developed for Hitachi and the IP contains customer-specific elements, an Infineon spokesperson said that the expertise and the copyrights to design similar silicon for other customers are under Infineon's control. "We could build a similar device also for any other customer", the spokesperson said.
