410900.gif

Single Package Is Less than 1/100th the Size of Previous Tuner2

Sharp Corporation has developed the VA3C5CZ920, the industry’s first1 tuner module compatible with GB20600-2006, the China Digital Television Terrestrial Broadcasting System Standard. Sample shipments will start in late January 2008. This tuner module is less than 1/100th the size of conventional “can” tuners3 for receiving China’s terrestrial digital broadcasts. The small package size of just 10.7 x 10.7 x 1.4 mm means that this tuner module can go into mobile equipment such as portable TVs and allow them to receive terrestrial digital broadcasts.

Established in August 2006, China’s terrestrial digital broadcast standard has begun test service and plans are for a gradual conversion to full-fledged service. This is fueling expectations for a growing market in mobile equipment capable of receiving high-quality HD broadcasts as the country heads for major events like the 2008 Beijing Olympics and Expo 2010 in Shanghai.

Unlike conventional can tuners, key component tuners like this one mainly go into mobile equipment and must therefore be extremely small. The VA3C5CZ920 answers this call with a compact, single package achieved through proprietary high-frequency and high-density-mounting technologies that came out of Sharp’s experience in developing tuner modules for One-Seg, Japan’s terrestrial digital broadcast format.
