简单介绍

XTA-0808: ATM-Ethernet media converter

产品描述

desc-ription:

xta-0808 is a high-speed, low-latency solution for ethernet lan and wan connection, which facilitates the integration of atm into any network cabling system by converting an atm cell to the ethernet packet format, and vice versa. the xta-0808 provides transparent operation of data rates up to 40 mbps in full duplex for each channel.
you can form a 24-channel eodsl co device by integrating three xta-0808 and one 24-port switch controller(such as xte-2402g). xta-0808 adopts utopia interface on a port-to-port basis, which is more cost effective and flexible.

xta-0808 contains eight atm-ethernet converting channels. it supports reversed sssmii interface for ethernet ports and utopia interface for atm circuits, and rfc 2864 ethernet bridging mode is supported. xta-0808 is manufactured on a 0.35-micro process and operates from a 3.3v core power. it is offered in a 128-pin tqfp package.

feature:

-single chip for eight-port atm(cell)/ethernet(packet) converter

-comply with rfc 2684 bridge mode

-llc/vc-mux encapsulation

-aal5 sar(segmentation and reassembly)

-utopia level 2(ul2) interface up to eight xdsl ports

-eight-bit ul2 data bus up to 40mhz

-embedded table configuration by serial interface (mdc/mdio)

-embedded table supports configurable vci/vpi per xdsl port.

-reversed sssmii interface on eight 100mbps full duplex ethernet ports

-ieee 802.3x flow control compliant

-downstream memory buffer size up to 16 packets and 8 packets for upstream

-memory segmentation by page, 256 bytes per page.

-3.3v, 0.35 m cmos core

-62.5mhz system frequency

-128 pins tqfp package

benefit:

-eight channel atm-ethernet media converter

-flexible for eodsl integrated application

-embedded memory for packet/cell buffer

-ieee802.3x flow control
