LGS-8G75 and LGS-8G77 Improve Terrestrial DTV Reception, While Offering New Interfaces and Reducing Space and Power Requirements

FREMONT, Calif. — Legend Silicon Corporation, a leading technology company delivering semiconductor solutions for digital terrestrial high definition TV (HDTV), today introduced two new high-performance terrestrial demodulators for the China market. The LGS-8G75 and LGS-8G77 significantly improve end-user reception while offering unparalleled integration, new interfaces and space savings for mobile and portable applications. Fully compliant with China’s GB20600-2006 digital terrestrial television broadcast (DTTB) standard, the demodulators deliver industry-leading reception of both single- and multi-carrier broadcasts.

“More than 840 million television viewers in China watched the Olympic opening ceremonies, according to CSM Media Research. The Olympics offered the perfect opportunity for CCTV, China’s national television network, to showcase the capabilities of GB20600-2006 standard, which we co-invented and developed,” said Ben Runyan, vice president of marketing of Legend Silicon. “With our new products, Legend Silicon continues to demonstrate its leadership by bringing this digital television standard to virtually any device with a screen.”

The LGS-8G75 and LGS-8G77 are the first two members of the LGS-8G70 family, which bring higher levels of integration, performance and functionality to the market. These products support single- and multi-carrier broadcasts, integrate analog to digital converters (ADCs) and time de-interleaver memory, and provide correction for silicon tuner IQ imbalance. Both demodulators are packaged in a 10mm x 10mm 144 pin ball grid array (BGA). Some other key aspects of these products are:

  • LGS-8G75: Pin compatible to Legend Silicon’s highly successful LGS-8GL5, this demodulator improves single-carrier performance, lowers power and provides additional protection against adjacent channel interference compared to the previous generation.
  • LGS-8G77: Through its integration of a universal serial bus (USB) and secure digital input/output (SDIO) interfaces, this demodulator reduces critical board space and power requirements for mobile and laptop products.

“Designed to give the ultimate in flexibility and performance, Lifeview USB products enable users to watch digital TV when and where they want,” said Sherlock Shih, CEO at Lifeview. “We chose the Legend Silicon LGS-8G75 because it is well suited for integration into PC laptop designs in a miniCard, and these demodulators can be used for PCIe and Expresscard applications as well. And, by reducing the power and space requirements, it maximizes TV viewing time on those portable devices.”

Pricing and availability

The LGS-8G75 and LGS-8G77 are currently in production. Volume pricing for both demodulators is available upon request.
