CUBIT Device
CellBus Bus Switch TXC-05801 DATA SHEET FEATURES DESCRIPTION
UTOPIA or ALI-25 physical-layer cell interface CUBIT is a single-chip solution for implementing low-cost ATM multiplexing and switching systems, Inlet-side address translation and routing header based on the CellBus bus architecture. Such systems insertion, using external SRAM are constructed from a number of CUBIT devices, all Programmable OAM cell routing interconnected by a 37-line common bus, the CellBus CellBus bus access request, grant reception and bus. When operating at a 38 MHz clock rate, a CellBus bus transmission bus system can handle 1 Gbit/s of net ATM cell band CellBus bus cell reception and address recogniwidth. CUBIT supports unicast and multicast transfers, tion and has all necessary functions for implementing a Outlet cell queuing: various modes switch: inlet queuing, cell address translation, cell routing, and outlet cell queuing. Ability to insert GFC field in real time Ability to insert FECN indication, under programmable conditions Support for ABR-type traffic with minimal cell loss Ability to send and receive cells for control purposes over same CellBus bus Cell insertion and extraction via microprocessor port APPLICATIONS Master bus arbiter included in each CUBIT Internal GTL transceivers for CellBus bus connecDataSheet4U.com ATM LAN hub tion Router Front-End Interface port to translation table SRAM ATM multiplexer/concentra...
