JUNE 3, 2008 -- Vitesse Semiconductor Corp. (search for Vitesse) says that CyberTAN, a Taiwanese ODM of broadband networking equipment, is using Vitesse's G-RocX Gigabit Router SoC in a production-level EPON FTTH residential gateway. The SoC integrates a CPU with Gigabit Ethernet switch and voltage-mode PHY technology into a single chip. Vitesse says that the low-power SoC provides the performance needed to support triple-play networking services while simultaneously lowering overall bill of material (BOM) costs.
Vitesse's G-RocX VSC7501 provides Gigabit LAN connectivity, including Gigabit Ethernet system performance and quality of service (QoS) technology, for home residential gateways. This enables CyberTAN to quickly develop its family of gateways that meet the carrier-class video, data, and voice delivery requirements of the FTTH market, the chip vendor says.
The G-RocX VSC7501 includes 10/100/1000-Mbit/sec copper PHY ports, line-side termination resistors, a router engine with a custom Hardware Network Address Translation (HNAT), a UART, two USB 2.0 interfaces, and a PCI port. The enhanced triple play experience is delivered through a Gigabit Ethernet WAN port. The custom HNAT, which offloads packet header extraction, SIP, ARP, and session table search, enables full gigabit per second line rate routing. Vitesse says that this router engine architecture significantly offloads software drivers and accelerates the delivery of wired and wireless Ethernet packets. G-RocX requires less than 3 W, enabling the removal of heat dissipating fans and the use of less expensive plastic housings.
