Mindspeed Rolls Out Highly Integrated and Power-efficient IMA Processor

12/16/2003 - Mindspeed Technologies, Inc. (NASDAQ: MSPD), a leading supplier of semiconductor solutions for network infrastructure applications, introduced the industry's most highly integrated and power-efficient 32-port single-chip IMA processor for access concentrators, digital subscriber line access multiplexers (DSLAMs), third-generation (3G) wireless networking equipment, multi-service platforms and T1/E1 and DSL line cards.

Mindspeed's 32-port M28529 IMA processor is used to provide bandwidth between T1/E1 and T3/E3 speeds. Consuming 40 percent less power than any other 32-port IMA solution on the market, the M28529 processor also is the most highly integrated solution of its kind to include 512 Kbytes of on-chip memory that surpasses the standards requirements of 25 milliseconds of differential delay compensation. This eliminates the need for an external memory device, which saves cost and board space.

A complete Transmission Convergence (TC) block provides Utopia 2 or serial line connectivity to T1/E1 framers and DSL transceivers for each link. The combination of a Utopia interface on the physical layer (PHY) side, and the ability to deliver the industry's highest data rates per link makes both the M28529 and the 16-port M28525 processors ideal for DSL applications. Mindspeed's third generation of IMA devices include a field-proven, comprehensive software package.

The inclusion of integrated memory, low power consumption and comprehensive software support is particularly important in wireless network infrastructure applications.

These features led ZTE Corporation to select the M28529 processor. ZTE is China's largest listed telecommunications equipment provider specializing in offering customized network solutions for telecom carriers worldwide. The M28529 processor gives ZTE the flexibility to develop IMA-32 line cards for both radio network controller (RNC) and core network (CN) equipment, in either wideband code division multiple access (W-CDMA) or CDMA2000 networks.

"Mindspeed's M28529 processor has significantly cut the costs and size of our IMA-32 line cards, while providing excellent power efficiency," said Li Guang, general manager for ZTE's 3G Public Platform Division. "Mindspeed has a long history of leadership in IMA solutions using a field-proven architecture, and the company is a valued supplier that continues to offer superior product features and outstanding software support."

"We are pleased to have been selected by ZTE for another IMA design," said Taqi Mohiuddin, product line manager with Mindspeed. "ZTE has become an important global player in the telecommunications industry with products deployed in more than 40 countries and regions, and Mindspeed has played a key role in helping ZTE deliver outstanding results to its customers."

Technical Details
Mindspeed's M28525 and M28529 devices are general-purpose processors suitable for both T1/E1 and DSL applications. The new devices meet the ATM Forum IMA specifications AF-PHY-0086.001 versions 1.0 and 1.1. Both devices have 512Kb of on-chip SRAM memory for compensation of differential delay. This memory block is capable of supporting 50ms to 100ms of delay, sufficient to meet the requirements of most applications. Additionally, an external memory interface is also available on both devices to support up to 275ms of delay.

Both the M28525 and M28529 have a standard Utopia Level 2 system interface. The parts have 3 PHY interfaces to choose from, giving the designer maximum flexibility and design choice. Standard Utopia Level 2, serial TDM streams, and 8MHz interleaved highway interfaces are available as multiplexed options.

The IMA engine supports industry-high link data rates up to 8.192Mbps, with up to 16 links running concurrently. Data rates for the multiple xDSL standards that are in use are migrating towards continually higher speeds and these devices help future proof designs. The IMA block is capable of forming groups of up to 16 links for the M28525 or 32 links for the M28529. The IMA block also may be bypassed on a per-port basis to enable any combination of IMA-enabled or non-IMA-enabled links.

The M28525 and M28529 devices are packaged in a 27-mm, 484-pin ball grid array. The M28525 device is priced at $105.60 in OEM quantities of 10,000, and the M28529 device is priced at $140.80 in the same quantities. Samples will be available in January 2004, and volume production is scheduled to begin in the first calendar quarter of 2004.
