Description

CUBIT-ProTM is a single-chip solution for implementing cost effective ATM access systems. TXC-05802B is based on the CellBus® Bus Architecture (CellBus). Such systems are constructed from a number of CUBIT-Pro devices, all interconnected by a 37-line common bus, the CellBus bus. When operating at a 38 MHz clock rate, a CellBus bus system can handle 1 Gbit/s of net ATM cell bandwidth. CUBIT-Pro supports unicast and multicast transfers, and has all necessary functions for implementing a switch: cell address translation, cell routing, and outlet cell queuing.

The TXC-05802B has GTL+ drivers with improved slew rate control. This ensures CellBus compatibility with new generations of CellBus devices. The TXC-05802B is a functional replacement for the TXC-05802 and is targeted for GTL+ applications. It can operate with dual 5 V and 3.3 V supplies, or a single 3.3 V supply.
