Speeds Development of CPRI Interfaces for Next-Generation LTE, WiMAX as well as Multi-Mode Products
Altera Corporation currently voiced a accessibility of a Common Public Radio Interface (CPRI) v4.1 egghead skill (IP) core. Supporting channel speeds up to 6.144 Gbps, a CPRI v4.1 IP core supports a LTE as well as WiMAX standards as well as offers bequest await for WCDMA, CDMA as well as alternative air-interface standards in a singular system. It enables developers to simply ascent from exclusive CPRI implementations to a rarely configurable resolution ancillary today’s standards, mending patron capability as well as price of ownership.
This entirely configurable, off-the-shelf resolution complements Altera’s 40-nm portfolio of Arria® II GX FPGAs for up to 3.072G CPRI line rates as well as Stratix® IV GX FPGAs as well as HardCopy® IV ASIC solutions for up to 6.144G CPRI line rates. The IP core targets a far-reaching operation of wireless applications together with multi-mode air-interface support, single-hop as well as multi-hop complement topologies as well as modernized MIMO receiver configurations. It comes finish with exam benches which perform start-up sequences for usual pattern modes so developers can get up to speed fast as well as concentration on differentiating their product.
“There is an augmenting direct from a commercial operation worldwide to yield off-the-shelf solutions for implementing usual functions in wireless basestations,” pronounced Arun Iyengar, comparison executive of Altera’s promote as well as communications commercial operation units. “The Altera CPRI IP core enables commercial operation to minimize pattern efforts as well as accelerate time to marketplace for standards-based air wave entrance products whilst still maintaining a capability to customize for a singular mandate of their applications. With augmenting direct for bandwidth in a CPRI links, this core total with a transceiver record completely positions OEMs to residence destiny basestation mandate together with 10-Gbps CPRI links.”
The Altera® CPRI v4.1 IP core includes pass facilities such as:
- Built-in await for CPRI v4.1 as well as back concordant mapping methods
- Line rate await up to 6.144 Gbps requiring a time rate as low as 153.6 MHz to palliate timing closure
- Up to twenty-four receiver carriers per IP core
- Integrated 10/100 Ethernet MAC as well as HDLC controllers
“We have been gratified which Altera has comparison a CPRI v4.1 IP record to enhance their IP portfolio offering,” pronounced Christian Lanzani, comparison product physical education instructor in Radiocomp ApS. “This record is a many compact, stretchable as well as in-the-field entirely accurate CPRI interface resolution accessible for distributed bottom stations.”
This brand new CPRI v4.1 core adds to Altera’s extended portfolio of wireless basestation record together with IP, anxiety designs as well as DSP Builder apparatus await for formulating optimized digital downconverters (DDC), digital upconverters (DUC), design cause rebate (CFR), digital predistortion (DPD), as well as alternative functions.
Availability
The CPRI v4.1 core is accessible possibly in encrypted IP or as source formula for finish user control. Contact your Altera sales deputy for pricing. The CPRI IP is upheld in a Quartus® II program chronicle 9.0 SP2, for all Altera 40-nm transceiver-based products. For finish information, revisit www.altera.com/pr/products/ip/communications/cpri.
