Microtune's RF Technology Dominates Latest CableLab's Certification Wave in DOCSIS-Qualified Cable Modems

7/2/2002 - Microtune™, Inc. (NASDAQ: TUNE) today announced that 75% of the cable modems certified for DOCSIS™ 1.1 by Cable Television Laboratories, Inc. (CableLabs®) in Certification Wave 22 deployed its radio frequency (RF) electronics. With these newly certified products, Microtune extends its RF technology leadership to cable modems that expand the services-high-speed Internet access, Voice over IP (VoIP), home networking, wireless connectivity or tiered service offerings-available to consumers from broadband cable equipment.

Testifying to its dramatic success, Microtune was the only RF supplier furnishing a silicon tuner in cable modems qualified to the 1.1 version of the standard in this testing round. Microtune provided the silicon tuner for the ready-to-manufacture cable modem submitted by Texas Instruments that attained DOCSIS 1.1 certification. This solution was a result of the collaboration between the two companies. Microtune also provided the RF tuner for the only two qualified cable modems that offered wireless local area network (WLAN) capabilities.

Overall, including DOCSIS 1.0 certifications, Microtune supplied silicon tuners, amplifiers or silicon-based transceivers in 60% of the cable modems that received the CableLabs seal of approval.

"This most recent DOCSIS Certification Wave activity continues to solidify our position as the number one RF technology supplier to the cable modem market," stated Douglas J. Bartek, Chairman and CEO of Microtune. "Our success reflects our goal of providing customers a suite of cost-effective RF products that speed their time-to-market, certification and manufacturing. To directly address their increasing competitive and pricing pressures, our products also offer customers a critical migration path to continued cost, power and performance improvements."

To date, Microtune has provided the RF tuner solution in one or more models for 42 of the 67 companies that have been awarded DOCSIS or EuroDOCSIS certification, representing more than 60% of the certified suppliers.

When integrated into consumer cable products, Microtune's RF building blocks enable video, high-speed data and voice services via the broadband cable network. Designed to support the DOCSIS interoperability standards, its silicon and systems solutions meet the discriminating RF performance, power and reliability requirements specified by major suppliers for high-volume cable modem manufacturing and deployment.

Microtune offers a complete portfolio of radio frequency products for broadband cable applications, ranging from silicon tuners and broadband amplifiers to production-ready RF subsystems and wireless connectivity system-on-chip offerings. These products function as the critical RF gateway in consumer premises equipment, receiving and transmitting analog/digital data to and from the head end to the rest of the system's electronics. They are essential RF components in accelerating the broadband deployment of voice, video and data via two-way cable and/or terrestrial communications systems.
