Speeds Development of CPRI Interfaces for Next-Generation LTE, WiMAX
and Multi-Mode Products
Altera
Corporation (NASDAQ: ALTR) today announced the availability of its
Common Public Radio Interface (CPRI) v4.1 intellectual property (IP)
core. Supporting channel speeds up to 6.144 Gbps, the CPRI v4.1 IP core
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.
This fully configurable, off-the-shelf solution complements Altera's
40-nm 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.
“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.”
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 6.144 Gbps requiring a clock rate as low as
153.6 MHz to ease timing closure
-
Up to 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.”
This new CPRI v4.1 core adds to Altera's broad portfolio of wireless
basestation technology including IP, reference designs and DSP Builder
tool support for creating optimized digital downconverters (DDC),
digital upconverters (DUC), crest factor reduction (CFR), digital
predistortion (DPD), and other functions.
Availability
The CPRI v4.1 core is available either in encrypted IP or as source code
for complete user control. Contact your Altera sales representative for
pricing. The CPRI IP is supported in the Quartus®
II software version 9.0 SP2, for all Altera 40-nm transceiver-based
products. For complete information, visit www.altera.com/pr/products/ip/communications/cpri.
