.. CUBIT®-Pro Device Cell Bus® Bus Switch TXC-05802B DATA SHEET Features DESCRIPTION CUBIT-Pro TM is a single-chip solution for implementing - UTOPIA and 16-Bit (ATM or PHY) Layer cell interfaces cost effective ATM access systems. It is based on the Cell Bus® Bus Architecture (Cell Bus). Such systems are - Inlet-side address translation and routing header constructed from a number of CUBIT-Pro devices, all insertion, using external SRAM of up to 256 k B interconnected by a 37-line mon bus, the Cell Bus - Programmable OAM-cell and RM-cell routing bus. When operating at a 38 MHz clock rate, a Cell Bus - Cell Bus bus access request, grant reception and bus system can handle 1 Gbit/s of net ATM cell bandbus transmission width. CUBIT-Pro supports unicast and multicast trans- Cell Bus bus cell reception and address recognition fers, and has all necessary functions for implementing a - Outlet cell queuing: various modes switch: cell address translation, cell routing, and outlet - Ability to insert GFC field in real time cell queuing. - Ability to insert FECN indication, under program The TXC-05802B has GTL+ drivers with improved slew mable conditions rate control. This ensures Cell Bus patibility with new - Ability to send and receive cells for control purposgenerations of Cell Bus devices. The TXC-05802B is a es over same Cell Bus bus functional replacement for the TXC-05802 and is tar- Cell insertion and extraction via microprocessor geted for GTL+ applications. It can operate with dual 5 V port and 3.3 V supplies, or a single 3.3 V supply. - Master bus arbiter and frame pulse generator included in each CUBIT-Pro, with enabling pin APPLICATIONS - Improved internal GTL+ transceivers for Cell Bus - x DSL Access Multiplexer bus connection . - Remote Access Equipment - Interface port to translation table in SRAM - Cable Modem Access Multiplexer - Microprocessor control port, selectable for Intel or - ATM LAN hub Motorola interface - ATM...
