The MT2170 tuner offers the equivalent functionality of four DOCSIS 2.0 digital tuners in a highly integrated miniature package, shrinking the tuner footprint and reducing the power consumption by approximately 75% compared to pre-DOCSIS 3.0 multi-tuner solutions. Equally important, the MT2170 significantly reduces the radio frequency (RF) bill of materials costs.

o Microtune’s new DOCSIS 3.0 tuner enables a wider (100 MHz) and faster (160 Mbps) pipeline into the home, dramatically increasing cable modem transmission speeds and flexibility

o New tuner offers the equivalent functionality of four DOCSIS 2.0 tuners, shrinking RF footprint by 75%, cutting power consumption by 75% and significantly reducing BOM costs for DOCSIS 3.0 cable equipment manufacturers

When integrated into cable modems or video-over-IP set-top boxes, the MT2170 delivers speeds greater than 160 Mbps. This enhanced throughput will permit cable operators to cost-effectively offer bandwidth-intensive digital services today, to position their products for integrated service innovations in the future, and to aggressively compete with high-powered fiber-to-the-home networks. Cable premise equipment can be designed to support fast high-definition video downloads, video file exchanges, time-shifted and place-shifted video, Internet-Protocol (IP) voice and interactive on-line gaming.

PLANO, Texas–March 12, 2007–Leveraging both its experience and expertise as a leading silicon tuner supplier to the cable market, Microtune®, Inc. (Nasdaq:TUNE) today introduced the MicroTuner(TM) MT2170, the industry’s first 1-gigahertz (GHz) input tuner based on the new CableLabs® DOCSIS® 3.0 specification. Microtune’s new tuner chip is engineered to deliver the impressive data speeds (greater than 160 Mbps) and wider bandwidth (100 MHz) demanded by cable equipment manufacturers for an easy, reliable, and cost-effective way to implement DOCSIS 3.0.

The MT2170 is the first in a new generation of Microtune products to support the DOCSIS 3.0 industry specifications. In the cable modem, the tuner functions as a ‘gateway’ component; it receives and tunes the signals, embedded with data and/or voice, delivered over the cable network to the subscriber.
