Altera's 6.144 Gbps CPRI v4.1 IP Core for wireless applications

Altera has made available its Common Public Radio Interface (CPRI) v4.1 intellectual property (IP) core, with a channel speed up to 6.144 Gbps, and supports the LTE and WiMAX standards and offers legacy support for WCDMA, CDMA and other air-interface standards in a single system.

This fully configurable, off-the-shelf IP core complements Altera's 40-nm portfolio of Arria II GX FPGAs up to 3.072G CPRI line rates and Stratix IV GX FPGAs and HardCopy IV ASIC solutions up to 6.144G CPRI line rates. The IP core targeted for 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.

"There is an increasing demand from our customers worldwide to provide off-the-shelf solutions for implementing common functions in wireless basestations," said Arun Iyengar, senior director of Altera's broadcast and communications business units. "The Altera CPRI IP core enables customers to minimize design efforts and accelerate time to market for standards-based radio access products while still retaining the ability to customize for the unique requirements of their applications. With increasing demand for bandwidth in the CPRI links, this core combined with our transceiver technology solidly positions OEMs to address future basestation requirements including 10-Gbps CPRI links."

Key features are,

Built-in support with backward compatible mapping methods
Line rate support up to 6.144 Gbps with a clock rate of 153.6 MHz to ease timing closure
24 antenna carriers per IP core
Integrated 10/100 Ethernet MAC and HDLC controllers

"We are pleased that Altera has selected our CPRI v4.1 IP technology to expand their IP portfolio offering," said Christian Lanzani, senior product manager in Radiocomp ApS. "This technology is the most compact, flexible and in-the-field fully verified CPRI interface solution available for distributed base stations."
