Lantiq’s new ADSL chips add onboard Ethernet support
Lantiq has introduced a set of chips for ADSL gateways that directly integrate support for Ethernet and Gigabit Ethernet.
Lantiq’s Xway ARX300 device family for ADSL2/2+ customer premises equipment (CPE) designs has four iterations addressing different system configurations, ranging from cost-optimized fast Ethernet to feature-rich, high-performance Gigabit Ethernet systems, the company said.
The new chips integrate a complete ADSL PHY on-chip, including line-driver circuitry compliant with ITU-T G.992 for 28 Mbps downstream and 2.7 Mbps upstream data rates, supporting physical layer features such as erasure decoding and retransmission (G.998.4), Lantiq said.
The company has also integrated Gigabit Ethernet switch and Gigabit or Fast Ethernet PHYs.
The chips also support 802.11n Wi-Fi connectivity, at either 2.4 GHz or 5 GHz. Companion chips are used to implement Wi-Fi connectivity in either a 2 x 2 MIMO or 3 x 3 MIMO configuration.
The high-performance dual-processor architecture includes a 500 MHz CPU and dedicated 32-bit protocol processing engine that assures Gigabit routing performance with zero load on the application processor, the company said.
Xway ARX300 devices are available now for engineering development with key customers. Volume production to support customer rollouts will begin in the fourth quarter of this year.
