Market for Legend Silicon's Products
China is the world's largest television market with 380M households in 2007, and it is expected to grow even larger with the introduction of digital TV devices and programming in advance of the 2008 Beijing Olympics. As one of the co-inventors and developers of the China DTTB standard, Legend Silicon has a first-to-market advantage with products that support the design of both fixed and mobile applications. Legend Silicon's products use the technology they invented, Time Domain Synchronous-Orthogonal Frequency Division Multiplexing (TDS-OFDM), the core technology on which the China standard is based.
Legend Silicon has designed GB20600-2006 semiconductor products that offer:
■ high bandwidth to support HDTV and / or multiple SDTV channels;
■ low power dissipation for handheld applications;
■ small form factor for space constrained applications;
■ optimized multi-path performance that improves mobile reception under channel fading, echoes and impulse noise conditions;
■ high quality HDTV while moving at high speeds.

DMB-TH is a subset of the GB20600-2006 standard.
■ LGS-8G13-the first GB20600-2006 compliant solution in the market-a single chip demodulator that uses Time Domain Synchronous-Orthogonal Frequency Division Multiplexing (TDS-OFDM). It is a pin-compatible upgrade to the LGS-8913. This chip is intended as a seamless upgrade to customer's existing LGS-8913 based iDTVs and STBs to the GB20600-2006 standard.
■ LGS-8913-a single chip DMB-TH demodulator that uses TDS-OFDM. After the approval of the GB20600-2006 standard in August 2006, this was the first device available for customers to design in for integrated digital televisions (iDTVs), set-top boxes (STBs) and automobile receivers.
Portable Applications
■ LGS-8G75- a highly integrated single-chip China Digital Television Terrestrial Broadcasting System Standard (GB20600-2006) demodulator. Designed for single-carrier and multi-carrier mobile digital terrestrial reception of high definition, standard definition and other multimedia-based services, the LGS-8G75 is intended for low power and space constrained applications such as Portable Media Players (PMP), Mobile phones, USB sticks and laptops.
■ LGS-8GL5-a single chip demodulator fully compliant with the GB20600-2006 standard. It features an integrated analog-to-digital converter (ADC), fully integrated memory for the time de-interleaver and is available in a 144 ball-grid-array (BGA). The LGS-8GL5 can be used with low power,small footprint silicon tuners in portable and mobile applications.
