10006024-04 Katana®752i User’s Manual
1-1
Section 1
Overview
The Emerson Katana
®
752i is an intelligent input/output (I/O) processing blade for use in a
CompactPCI backplane. It is compatible with the CompactPCI Packet-Switched Backplane
(cPSB) and has two PCI Telecom Mezzanine Card (PTMC) sites that can support two tele-
communications interface cards, such as the Emerson PM/3Gv. The Katana®752i draws
processing power from its IBM PowerPC
®
750GL microprocessor, running at a speed of up
to 1GHz. A Marvell system controller serves as a PCI bridge. In the standard configuration,
the Katana®752i connects two Gigabit Ethernet ports to the front panel and two Gigabit
Ethernet ports to the J3 backplane connector, which (depending upon the configuration)
provides access to a rear transition module or cPSB. The Katana®752i supports various
memory configurations, user Flash memory, a front-panel serial port, and user I/O from the
PTMC sites. Optionally, the Katana®752i supports the H.110 Computer Telephony (CT) bus
and various clocking signals.
COMPONENTS AND FEATURES
The following is a brief summary of the Katana®752i hardware components and features:
CPU: The Katana®752i features an IBM 750GL central processing unit (CPU), operating at a rate
of up to 1GHz. The CPU is a 32-bit PowerPC RISC microprocessor with 32-kilobyte, Level-1,
data and instruction caches, as well as a one-megabyte, four-way, set-associative, Level-2
cache.
System Controller/PCI Bridge:
The Katana®752i employs a system controller/PCI bridge device from Marvell. The Discov-
ery
™
III MV64460 is a single-chip solution that provides a high-speed (up to 200MHz) 60x
bus interface, double-data rate (DDR) SDRAM controller, two 66-MHz PCI interfaces (64
bits for CompactPCI, 32 bits for PTMC sites), three 10/100/1000BaseT Ethernet MAC con-
trollers, two multi-protocol serial controllers (MPSC), an interrupt controller, and 32 gen-
eral-purpose input/output (I/O) signals. The MV64460 also includes an inter-integrated
circuit (I
2
C) interface.
