Altera First to Meet OBSAI Reference Point 3 Interface Specification

12/17/2003 - Altera Corporation (NASDAQ: ALTR) announced that it is the first FPGA vendor to meet the Open Base Station Architecture Initiative's (OBSAI) Reference Point 3 (RP3) interface specification. To meet OBSAI's specification, Altera has developed a reference design demonstrating the integration of the link-layer function, together with the PHY layer, within a single device. The Stratix GX FPGA family provides up to 20 bi-directional Gbps serial transceivers and gives base station manufacturers the flexibility to address macro, micro, and pico base station configurations. Additionally, with up to 40,000 logic elements (LEs) available, the Stratix GX family allows for the ability to integrate various functions on the radio frequency (RF) card such as DDC, DUC, and DPD all within a single device.

"We welcome this announcement from Altera of its support for the OBSAI radio-to-base band interface specification with an integrated PHY and link-layer solution for RP3," said Mr. Jukka Klemettila, chairperson of the OBSAI. "OBSAI aims to create an open market for cellular base stations. An open market will substantially reduce the development effort and costs that have been traditionally associated with creating new radio base stations."

OBSAI has a growing membership of close to 70 industry-leading telecommunications companies working together to define wireless base station specifications. The RP3 interface specification defines the way in which data and control information is to be exchanged between the base band and RF sections of the base station.

"Successfully meeting OBSAI's RP3 specification helps to ensure that Altera provides world-class products for next-generation base stations," said Arun Iyengar, director of Altera's wireless business unit. "The Stratix GX family delivers a complete solution for the mobile infrastructure industry, providing both flexibility and integration. In addition, Altera offers a seamless structured ASIC migration path with HardCopy Stratix GX devices that can reduce costs by over 60 percent."

About the Open Base Station Architecture Initiative
The OBSAI comprises close to 70 industry-leading telecommunications companies. OBSAI has created a set of open specifications to define a modular wireless base station architecture and detailed specifications for the three main internal interfaces. The aim of this initiative is to create an open market for base station modules and components to reduce development effort and cost, improve time-to-market, and accelerate the implementation of new and advanced services.
