MINDSPEED DEBUTS SINGLE-CHIP IMA FOR DSL AND T1/E1.

Mindspeed Technologies(TM), the Internet infrastructure business of Conexant Systems, Inc. (Nasdaq:CNXT), Newport Beach, Calif., has introduced a complete family of inverse multiplexing over ATM (IMA) devices designed for a wide range of T1/E1 and digital subscriber line (DSL) applications.

The CX2822x family delivers the only single-chip IMA devices -- with fully integrated differential delay SRAM -- available today for DSL applications. The new IMA chips, which are available in a wide range of port configurations from 2 to 32 ports, are the smallest and lowest power IMA devices on the market.

IMA provides the capability to provision bandwidth in T1/E1 or x.DSL increments, allowing networking systems to be more precisely scalable in the intermediate range between a basic T1 link (1.5 Mbps) or G.shdsl link (2.0 Mbps) and a DS3 connection (45 Mbps). Mindspeed's IMA solution is ideal for a wide range of networking systems, including access concentrators, digital subscriber line access multiplexers (DSLAMs), integrated access devices (IADs), DSL modems, third-generation (3G) wireless base stations, multi-service platforms, T1/E1 line cards and DSL line cards.

"Combined with Mindspeed's ZipWire G.shdsl modems, this new family of IMA devices offers our customers a complete, scalable DSL solution for new system designs, something none of our competitors can do today," said David Cayer, product line manager with Mindspeed Technologies. "In addition, the IMA chips complement our full line of T1/E1 components, allowing us to be a single source for T1/E1 solutions."

With the addition of the CX2822x family of IMA devices, Mindspeed offers a full portfolio of components for 3G wireless, customer premises and DSLAM applications, allowing networking equipment makers to purchase a complete set of integrated components from one supplier. Products include: network processors, T1/E1 framers, ZipWireMulti G.shdsl chipsets, hardware segmentation and reassemble (SAR) devices, and SONET framers. IMA is used in system solutions for DSLAMs, T1/E1 access and 3G Wireless. IMA is also used in customer premises equipment.

Technical Details

The CX2822x IMA family is available in three port densities: the 2-port CX28224, the 4-port CX28225 and the 8/32-port CX28229. All three devices are designed into a compact 17-mm 256-pin ball grid array (BGA) package, making them the smallest IMA chips on the market. With fully integrated differential delay SRAM, these devices are the first single-chip IMA devices for DSL.

The new IMA devices are the only IMA chips that support both Universal Test & Operations Physical Interface for ATM (UTOPIA) Level 2 and serial pulse code modulated (PCM) physical layer interfaces, making the chip ideal for either T1/E1 applications where PCM is the most popular interface or DSL applications where UTOPIA 2 is favored.

In addition, the CX2822x chips are the only IMA devices to have an integrated timing circuit that reproduces all possible DSL data rates, which is key to taking full advantage of the UTOPIA interface in DSL applications.

Mindspeed has had IMA products on the market since 1998. Mindspeed's IMA software and hardware algorithms are field-proven in all major IMA applications and have been fully tested for interoperability at the University of New Hampshire InterOperability Laboratory in 1998 and 1999.

Pricing and Availability

The CX2822x family is currently sampling and volume production will commence in January 2002. OEM pricing in volumes of 1,000 is $40 for the 2-port CX28224, $82 for the 4-port CX28225 and $135 for the 8-32 port CX28229.
