AE98

Advanced Information Data Sheet AE98 10 Gb/s Ethernet Optical Switch Port Features Provides LAN/WAN PHY layer operations for IEEE 802.3 10 Gigabit Ethernet Includes MAC layer ethernet functionality plus TCP/UDP and IP hardware assist Supports 16-bit wide LVDS 622/645 MHz System Packet Interface Level 4 (SPI-4). Delivers network side data over full-duplex 16-bit wide LVDS interface at 622 MHz in WAN mode or 644 MHz in LAN mode Performs SONET/SDH compatible encapsulation for transmission over OC-192/ STMo-64 or faster fiber links Includes 128 kbytes of buffering for Rx frames Provides network and chip statistics Requires minimal number of power supplies and external components for simplified integration and operation Manufactured in 0.15 micron CMOS technology General Description The Nortel Networks AE98 is a singlechip implementation of the PHY and MAC layer functions of a 10Gb/s Ethernet interface. The device is optimized for a System Packet Interface Level 4 (SPI-4) cell and packet interface for switches requiring costeffective access to 10 Gb/s Ethernet pipes. Typically the device accepts TCP/IP or UDP/IP packets, encapsulates them in Ethernet frames, encodes the data for efficient delineation and improved security, then packages it in SONET/ http://www.DataSheet4U.net/ SDH compatible WIS frames for transmission over high performance fiber links. WIS encapsulation can be bypassed to support LAN applications. The AE98 operates in full-duplex mode, providing independent t...
