To meet the needs of the rapidly growing Japanese mobile TV market, MediaPhy Corp. introduced the second member of its product family, the J-Solo. The all CMOS single-die J- Solo covers ISDB-T 1-3-13 segments, enabling seamless mobile TV throughout Japan.

Among the most advanced features of the J-Solo device is Smart-Seg that allows seamless switching between 1-seg, 3-seg and 13-seg modes, improving quality reception at all times in all locations. Smart-Seg operates by intelligently monitoring a number of reception parameters and automatically selecting the mode that offers the best reception. All features of Smart-Seg are user-configurable to manual or automatic modes. A proprietary architecture that enables ultra-low power consumption, Integrated Services Digital Broadcasting (ISDB)-T 1-seg operates at 80mW of power, while ISDB-T 13-seg requires only 120mW. It is ideal for implementation in cell phones, laptops, PDAs, PMPs, as well as automotive systems throughout the Japanese market.

Manufactured in 130nm RF CMOS process and in a 7mm x 7mm package, the single-die monolithic design features a complex frequency-agile radio and unique configurable hardware engine-based architecture (CHE). Due to its system-level design many components have been integrated into the single-chip in order to reduce the bill of materials (BOM) cost while enhancing overall system performance.

The chip will sample to customers this month and is expected to go into volume production in the first quarter of 2008.
