Lantiq Debuts Family of Gigabit Speed Gateway Processors

Lantiq expanded its family of home gateway processors with three, new single-chip Gigabit Ethernet processors designed for DOCSIS3.0, VDSL2 and xPON access technologies.


The new "XWAY" GRX168, GRX188 and GRX288 ICs are based on the same architecture as Lantiq's existing "XWAY" ARX100 and VRX200 ADSL2+ / VDSL2 solutions, with a 32-bit MIPS CPU core and separate 32-bit Protocol Processor Engine (PPE). The IPv6-ready PPE offloads all data routing from the CPU for optimal throughput at much lower system clock speeds than alternative chips and supports QoS features that enable smooth handling for concurrent serving of IPTV, voice lines, and data on wired or wireless LANs.


The designs also enable concurrent operation of 802.11n WLAN at 2.4 and 5 GHz with aggregate throughput up to 270 Mbps. The highest performance device in the family, "XWAY" GRX288, achieves routing throughput up to 2 Gbps to meet the requirements of xPON connectivity.


Lantiq said the common architecture of the xRX family allows system builders to produce a complete portfolio of home gateway solutions, including platforms that support new "Over-The-Top" services may be linked to a residence's broadband gateway via Ethernet/Gbps Ethernet, WLAN, or the emerging G.hn standard.


"As the range of applications running on or beside residential gateways broadens, system developers face challenges to meet operator requirements and match device functionality to suit specific customer needs within tight time and budget constraints," said Ulrich Huewels, Senior Vice President and Head of the Customer Premises Equipment Business Unit at Lantiq. "The GRX family provides full flexibility for our customers to design a range of solutions while controlling R&D spending. Lantiq continues to deliver on its promise: one investment, many applications."


Additional common features across the GRX family include integrated data encryption for IPsec and energy savings features that enable designs to meet the recently defined 2011/2012 requirements of the European Union Code of Conduct (CoC) on Energy Consumption of Broadband Equipment.
