Microtune Continues RF Silicon Leadership with Triple-Tuner Design for Multi-Functional, Multimedia Set-Top Boxes
-- Using three of its single-chip tuners, Microtune's proof-of-concept design demonstrates a complete RF/IF transceiver for cable set-top boxes, enabling multi-tuner personal video recording, picture-in-picture and DOCSIS Set-top Gateway applications
 
Plano, Texas, United States

Reinforcing its leadership position in radio frequency (RF) technology, Microtune(R), Inc (Nasdaq:TUNE) Wednesday announced that it has successfully demonstrated a concept design for future-proof cable set-top boxes that feature three silicon tuners. To develop the design, Microtune solved the extremely challenging RF problem of engineering three tuners to operate simultaneously in the same system without interference. Based on its most advanced tuner-on-chip technology, Microtune's forward-looking design verifies the real-world RF feasibility, performance and functionality of multi-tuner set-tops, media servers or residential gateways.

The triple-tuner architecture is the next stage in the evolution of the set-top box. It paves the way for advanced set-top functionality, including the ability of the cable subscriber to watch one channel while recording another.

"Microtune's triple-tuner design is engineered to be the smallest form-factor, highest performance RF front end for multi-tuner applications in the cable industry," said Albert Taddiken, Microtune's Chief Operating Officer. "It is a proof-of-concept that offers a practical demonstration of an RF solution that can be deployed today using Microtune's leading-edge products."

Integrated into a very small 5.3 x 5.5-inch form factor, the triple-tuner concept design is a complete RF/intermediate frequency solution. It encompasses all transceiver features and functions, from the RF input connector to the demodulator input interfaces. It features two of Microtune's high-performance MicroTuner(TM) MT2121 tuners and one MicroTuner MT2060 low-power tuner.

The tuners enable multiple streams of video and data inside the set-top box, supporting high-definition video, on-demand services, personal video recording, DOCSIS(R)-based high-speed Internet access and Digital Set-top Gateway (DSG)-based conditional access. The design also features Microtune's MicroStreamer(TM) MT1550 upstream amplifier for two-way communications and an out-of-band converter for conventional conditional access.

"Backed by our expertise in RF silicon, hardware and software and our understanding of our customer's systems issues," Mr. Taddiken added, "we engineered a solution that demonstrates what customers can achieve in their next-generation boxes -- superior performance, compliance to industry standards, support for legacy cable systems and low bill-of-materials cost."

Microtune Silicon Components

The MT2121 and MT2060 are patented, dual-conversion, single-chip tuners that require very few external components. The MT2121 provides excellent end-to-end linearity performance utilizing an integrated pre-select filter and is targeted for both analog/digital applications at frequencies up to 1 GigaHertz. The MT2060 is a low-power tuner designed to enable reception of digital data inside a set-top box.

The MicroStreamer MT1550 upstream amplifier, featuring an on-chip antialiasing filter, is engineered to support the increased upstream bandwidth capacity of the DOCSIS 2.0 cable modem specification.
