Analogue front end is dynamically reconfigurable
Lattice Semiconductor has added a new member to its ispPAC programmable analogue device family.
All 10GbE traffic that flows through the Avaya switches will be carried by Lattice's ORLI10G FPSC, a 10Gbit line interface device that acts as a high-speed conduit for Ethernet traffic transmitted over optical components.
Lattice's ORLI10G is the first programmable 10 Gigabit Ethernet line interface chip that provides data networking equipment designers with customisable, protocol-independent interfaces to high-speed optical transport facilities used in local area network (LAN), wide area network (WAN), and metro area network (MAN) deployments.
It implements a 10Gbit/s 16bit interface (XSBI) for optical transponders by combining optimised, embedded core logic together with up to 643K gates of programmable logic.

In-system reprogrammable 5th-order lowpass filter
Lattice Semiconductor has added to its ispPAC programmable analogue device family with the ispPAC81 in-system programmable continuous time filter.
The programmable logic employs Lattice's Orca Series 4 field-programmable gate array architecture, which is specifically designed to accommodate networking intellectual property (IP) cores.
"The Lattice ORLI10G is an elegant solution for enabling 10 Gigabit Ethernet capabilities on our Cajun switch products", said Roozbeh Ghorishi, Director of Engineering for Avaya.
"Lattice's FPSC technology provides us the flexibility of Ethernet PCS functionality implemented in programmable logic that seamlessly integrates with proven XSBI functionality in an embedded core.
Lattice has a novel system-on-a-chip approach that delivers clear time-to-market and customisation advantages while also addressing power, board space, interconnect, and design-complexity issues", Ghorishi added.
"Lattice is pleased to provide Avaya with a solution for 10 Gigabit Ethernet in their industry-leading Avaya Cajun family of MultiService Switches", said Stan Kopec, Vice President of Marketing at Lattice Semiconductor.
"The ORLI10G was designed to handle the demands of 10Gb Ethernet architectures, an essential technology for the rapidly expanding Metropolitan networking market.
The ORLI10G's embedded XSBI core solves high-speed transponder interface issues, while our PCS IP core provides the critical physical coding sublayer functions.
With leaders like Avaya designing our FPSC technology into their systems, Lattice's position as a recognised leader in 10GbE solutions is quickly becoming established".
"As communications networks become even more central to business, they will be called upon to do more: voice over IP, customer relationship management, video, unified messaging, supply chain management, process control and distance learning.
Meeting these demands will take more than just the muscle of additional bandwidth.
It will require the brains of smarter networking hardware and software.
That is where the AvayaMultiService Switches excel", said Graham Celine, Vice President, Solutions Management, Avaya.
At the top of Avaya's powerful line of Cajun network switches, the Avaya P580 and Avaya P882 scale beyond the shared bus and shared memory designs of other lower capacity switches.
The switches benefit from Avaya's standards-based VLAN support, impressive N+1 redundancy options, Avaya's comprehensive understanding of quality of service issues for voice and video traffic and labour-saving Avaya VisAbility Management Suite including Avaya MultiService Network Manager and Avaya Policy Manager software.
They are positioned to become core components of both current and future converged voice and data networks.
Lattice's ORLI10G encompasses forward clocked, 16bit transmit and receive 10Gbit/s interfaces (as per OIF 99.102.5).
This 16bit interface runs at 622, 645, 667, 781 and 850Mbits/s.
The device interfaces directly to industry-standard multiplexer and demultiplexer ICs.
This allows Lattice to offer cost-effective solutions for a variety of line interfaces: Optical Internetworking Forum (OIF) serdes - framer interface (SFI-4); 10 Gigabit Ethernet 16bit interface (XSBI); 10Gbit/s strong forward error correction (FEC) rates; and 12.5Gbit/s Super FEC rates.
Lattice's 10 Gigabit Ethernet PCS (physical coding sublayer) intellectual property core includes the following features: elastic buffers implemented as 256 x 72 FIFOs in embedded RAM; XGMII for interfacing to 10Gbit/s Ethernet MACs; 64/66b encoder/decoder; scrambler and descrambler with word aligner (x59 + x39 +1); quad 2.5Gbit/s Sonet/SDH to 10Gbit/s Sonet/SDH mux/demux functions; idle insertion and deletion; and a serial management interface compliant with Clause 45 of the IEEE802.3ae standard.
Lattice can deliver the PCS core as a ready-to-run bitstream or with VHDL source code, along with simulation and synthesis scripts, and complete documentation.
