Altera has announced the availability of its Common Public Radio Interface (CPRI) v4.1 intellectual property (IP) core.

Supporting channel speeds up to 6.144Gbit/s, the core supports the LTE and WiMAX standards while providing legacy support for WCDMA, CDMA and other air-interface standards.

Offered for the firm's 40nm portfolio of Arria II GX FPGAs for up to 3.072G CPRI line rates and Stratix IV GX FPGAs and HardCopy IV Asics 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 CPRI v4.1 core is available either in encrypted IP or as source code for complete user control.
