DESCRIPTION
CUBIT-Pro
TM
is a single-chip solution for implementing
cost effective ATM access systems. It is based on the
CellBus
廬
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 band-
width. CUBIT-Pro supports unicast and multicast trans-
fers, 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 tar-
geted for GTL+ applications. It can operate with dual 5 V
and 3.3 V supplies, or a single 3.3 V supply.
