Lantiq Samples ADSL2/2+ Gateway System-on-Chip

Lantiq unveiled its XWAY ARX300 device family for new ADSL2/2+ Customer Premise Equipment (CPE) designs. Four versions will be offered for different broadband gateway models. Key features include:


  • 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), directly benefiting Internet Protocol Television (IPTV) applications.


  • Fully integrated Gigabit Ethernet switch and Gigabit or Fast Ethernet PHYs.


  • Integrated, flexible 802.11n Wireless LAN (WLAN) connectivity supporting 2.4 GHz or 5 GHz frequency band operation. XWAY WRX312 (2x2 MIMO) and XWAY WRX313 (3x3 MIMO) companion chips are low power multi-standard IEEE 802.11 a/b/g/n RF transceiver with integrated power amplifier for 2.4 GHz band operation.


  • Two device versions: XWAY ARX382 and XWAY ARX388 derivatives leverage Lantiq’s extensive voice communications and home networking portfolio in multiple reference designs, including XWAY SLIC 100 voice interface, COSIC Modem DECT/CAT-iq single-chip device, and XWAY HNX G.hn chipsets for powerline/phone line/copper wire connectivity.


  • Low system Bill of Materials (BOM)


  • 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.


  • Fully-compliant 802.11n.e/i/h WLAN performance at up to 300 Mbps with zero-packet-error rate technology and “Thick MAC�? architecture to offload processor intensive operations from the main CPU supports carrier grade wireless links for rich media, including IPTV.


  • Designed with power management mechanisms to meet European CoC v4 and beyond requirements.
