Microtune Ships 10 Millionth Cable Modem Tuner; Solidifies Position as a Leading DOCSIS-Based Tuner Supplier to the Cable Broadband Access Market

7/10/2002 - Microtune™, Inc. (NASDAQ: TUNE) solidified its position as a leading radio frequency (RF) supplier in the standards-based cable access market with the shipment of its 10 millionth cable modem tuner. This tuner, the MicroTuner™ MT2040 single-chip integrated circuit, is based on the DOCSIS™ 1.1 standard and shipped on July 1, 2002 to Samsung Electronics Co., Ltd. This achievement was reached three years after Microtune introduced its first-generation cable modem tuner solutions, developed to deliver the high-performance, low-power RF capability required for high-speed Internet access via two-way cable communications.

"Shipping our 10 millionth cable modem tuner is a significant milestone," commented Douglas J. Bartek, Chairman and CEO of Microtune. "It reflects the continuing demand by worldwide consumers for high-speed broadband access and demonstrates our aggressive strategy of providing customers a portfolio of tuner options based on innovative RF silicon and systems technology, superior price/performance and streamlined manufacturability."

A key element of Microtune's market success has been anticipating customer demand for RF components that support international standards, such as the 1.0, 1.1 and 2.0 versions of DOCSIS and Euro-DOCSIS. The company has continued to evolve its tuner technology to meet the increasingly complex requirements of these cable specifications, as well as the new services fostered by them, including Voice over Internet Protocol (VoIP), rich multimedia, gaming, home networking and videoconferencing.

In the process, Microtune's RF technology was responsible for a number of industry firsts, including the first cable modems based on a true single-chip tuner technology for DOCSIS 1.0 and 1.1 certifications. Recently, Microtune provided the RF tuner and amplifier core for a DOCSIS 2.0-based cable modem that received the CableLabs® seal of approval in Certification Wave 21.

As customers' requirements have changed over the last three years, particularly in the demand for lower cost, lower power and more manufacturable solutions, Microtune has kept pace with these needs by introducing new breeds of tuners, as typified by Microtune's fifth- generation MicroTuner MT2050 single-chip integrated circuit. These tuner solutions were engineered to reduce RF price, performance, size and power barriers, enabling cable manufacturers to place more cost-efficient, more reliable end products into high-volume production.

Also critical for manufacturers, Microtune's RF technology provides a reliable solution that eliminates the problems that have plagued competing silicon tuner chip sets. These include microphonics, which can cause a loss of signal, and electrical spikes, which can damage the cable modem.

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.
