Infineon Technologies AG recently introduced an advanced hard disk drive read channel core, the first IC implemented in the company's 90nm process technology. Developed in cooperation with Hitachi Global Storage Technologies (Hitachi GST), the read channel core is a milestone on the path to developing high-integration controller chips for next generation hard disk drives, said the press release.

"Migration to 90nm of the Infineon read channel core enables the HDD industry to meet next generation product requirements, including higher data rates, reduced power consumption and smaller die-size leading to advanced SOC solutions at competitive cost," said Sandro Cerato, GM and VP at Infineon ADS-ASIC and design solutions. "The first tested read channel core silicon has demonstrated that the PLL is able to reach up to 3.6GHz speed and that the analog front-end signal path allows for datarates up to 2.7Gbps. This is an increase of approximately 50 percent compared to advanced read channels in 130nm technologies."

Infineon's 90nm read channel technology leverages on a common architecture and is applicable to all HDD segments, including enterprise, desktop, mobile and ultra-low power. The requirements of the different HDD platforms are achieved by customizing the designs to the specific target parameters of each market segment. In addition, the new read channel technology generation supports advanced features such as perpendicular recording and leverages on second-generation Reverse Concatenation coding to deliver state-of-the-art signal-to-noise-ratio performance for significantly improved storage densities, said Infineon,

A second implementation, currently in development for battery operated applications, targets an exceptionally low power dissipation. It will also provide superior stand-by power and leakage current performance thanks to Infineon's 90nm process technology.

The new HDD controller from the Infineon can be manufactured worldwide in multiple fabs, providing customers with supply-chain flexibility and opportunity to expand which is a very important value proposition in the hard drive industry. Fabs currently offering Infineon's 90nm technology include Infineon's Dresden fab in Germany and United Microelectronics Corp. in Taiwan.
