Altera CPRI v4.1 IP Core Targeted at Wireless Basestation, Remote Radio Head Design

Altera Corp.'s Common Public Radio Interface (CPRI) v4.1 intellectual property (IP) core features channel speeds up to 6.144Gbps, supports the LTE and WiMAX standards, and offers legacy support for WCDMA, CDMA and other air-interface standards in a single system. It enables developers to easily upgrade from proprietary CPRI implementations to a highly configurable solution supporting today's standards, improving customer productivity and cost of ownership.

The fully configurable, off-the-shelf solution complements Altera's 40nm portfolio of Arria II GX FPGAs for up to 3.072G CPRI line rates and Stratix IV GX FPGAs and HardCopy IV ASIC solutions for up to 6.144G CPRI line rates. The IP core targets a wide range of wireless applications including multi-mode air-interface support, single-hop and multi-hop system topologies and advanced MIMO antenna configurations. It comes complete with test benches that perform start-up sequences for common configuration modes so developers can get up to speed quickly and focus on differentiating their product.

The Altera CPRI v4.1 IP core includes key features such as:
• Built-in support for CPRI v4.1 and backward compatible mapping methods
• Line rate support up to 6.144Gbps requiring a clock rate as low as 153.6MHz to ease timing closure
• Up to 24 antenna carriers per IP core
• Integrated 10/100 Ethernet MAC and HDLC controllers
