I-Cube Introduces 340-Port Crosspoint Switch for Input/Output Intensive Applications

Highly Flexible, Low-Power CMOS Device Eases Design of Telecomm Equipment



Apr 16, 2001, 01:00 ET from I-Cube, Inc.

    CAMPBELL, Calif., April 16 /PRNewswire/ -- I-Cube, Inc., today announced
 the newest member of its MSX(TM) family of SRAM-based, in-system programmable,
 digital crosspoint switches.  The MSX340 Crosspoint Switch allows OEMs to
 develop scalable system designs that can be easily modified to meet growing
 customer needs for increased I/O density.  The enhanced feature set of the
 MSX340 targets key specifications for such telecommunications applications as
 digital cross-connects and other access products.
     The foundation of the MSX340 Crosspoint Switch is I-Cube's
 silicon-efficient non-blocking crossbar architecture that uses the switch
 matrix to connect input/output buffers in one-to-one or one-to-many
 connections.  The MSX340 features a non-blocking switch matrix, providing
 340 individually configurable I/O ports and double-buffered configuration RAM
 cells for simultaneous global updates.
     "The MSX340 is a lower power, more cost-effective version of the MSX532,
 which remains the industry's largest switch matrix," said Sean Long, vice
 president of sales and marketing at I-Cube.  "The MSX340 retains all the same
 high-performance features of the MSX532, such as double-buffering, but with
 fewer ports.  With more and more telecomm systems being designed for
 3.3 volts, the MSX340 is the perfect low-power alternative to other higher
 power crosspoint switches."
 
     High-Performance Switching Matrix
     The MSX crossbar switch matrix, built in a 0.35-micron CMOS process,
 offers high performance and an aggregate bandwidth of over 25 Gigabits per
 second for bit-oriented applications.  The individually configured I/O buffers
 can be programmed to serve as inputs or outputs, to provide bi-directional
 operation, or to operate in Bus Repeater(TM) mode.  The MSX340 allows
 designers to select signal direction and data flow mode.
     The device also allows next-neighbor clocking, meaning that any I/O pin
 can be used as a clock source for an adjacent I/O pin.  This feature allows
 the device to independently switch different speed inputs at the same time
 since each input can have its own clock source.
     Additionally, the MSX340 switch matrix offers unique double-buffered
 configurable SRAM cells.  This double buffering allows designers to use the
 device for both bit switching and bus switching by simply enabling or
 disabling this feature.  The inherent flexibility of the switch matrix, when
 coupled with double-buffering, enables users to design a bus switch that can
 support a variety of bus widths.
     The device offers tight skew and identical pin-to-pin delays.  The MSX
 device offers a flow-through NRZ (Non-Return to Zero) data rate of
 150 Megabits per second and registered clock frequencies of 75MHz.  The device
 operates at 3.3 volt with LVTTL (Low Voltage TTL) I/Os.
 
     Fast, Flexible Programming Interfaces
     Designers can configure the device's switch matrix, I/O buffers, and
 control registers by using either the JTAG serial interface or the faster
 RapidConfigure(TM) interface.  The dedicated RapidConfigure parallel interface
 has 28 pins, allowing connections to be made in as little as 12ns.  Designers
 can use the "clear all connection" function incorporated in the RapidConfigure
 interface to clear all matrix connections from a single port.
     The JTAG interface is designed in compliance with the IEEE-1149.1 and has
 five pins (TDO, TMS, TDI, TRST, and TCK), allowing boundary scan testing as
 well as device configuration and verification.
 
     Pricing and Availability
     The MSX340 is available in production volumes now.  The device is packaged
 in a 480-Ball Grid Array (BGA) and is priced at $134.00 in 1000-unit
 quantities.
