Crystal technician first STB source decoder IC helped domestic import farewell

Hangzhou imagesilicon (Image Silicon) announced that it will be officially released the country's first independent intellectual property rights of the digital TV set-top box special source decoder chip IS1521. Imagesilicon said, the successful development of the chip and release means Chinese digital TV industry will bid farewell to the era of high priced imports depends entirely on the chip.

According to reports, IS1521 using 0.18 micron manufacturing technology, LQFP144 package, the kernel uses 32 bit RISC CPU, 32 bit bus structure, the working frequency of 108MHz, to support the 5 layer graphic display, built-in common descrambling module supports CA (CA), support data broadcasting, middleware and EPG operating system, using C and Linux. Provide a complete development tools, support the user developed more applications in open software environment.

According to the company responsible for marketing deputy general manager Pan Jiangdong introduction, the chip is in fully understanding and analyzing the overall conversion of digital cable television application characteristics and requirements on the research and development, has a very strong applicability and high price, is believed to be a good role to accelerate the development of digital TV industry Chinese the. The chip from the R & D early developing thought of high performance and low cost, which is reflected in the architecture, structure design, algorithm implementation, manufacturing process until the package design and other aspects, the target market is very clear to lock in the service China cable overall transfer, provide the most suitable conditions China set-top box the core chip products to customers.

The product is also suitable for DVB-S high-end market and export market, is expected to replace the existing imported products, and significantly reduce the cost of satellite set-top boxes.

In addition to IS1521 products, Hangzhou imagesilicon company also for satellite and cable TV market FTA simultaneous launch of FTA digital TV set-top box special source decoder chip IS1561, using the LQFP128 package, as a necessary supplement of low performance chip products are widely used on the market, in order at the same price basis, to enhance the overall performance of the class the set-top box products.

IS1561 also uses the 0.18 micron manufacturing process, LQFP128 package, the kernel uses 32 bit RISC CPU, 32 bit bus structure, the working frequency of 108MHz, to support the 5 layer graphic display, operating system using C Linux, and provide complete development tools, support the user developed more applications in open software environment.

Pan Jiangdong introduction, the chip for the existing FTA set-top boxes, especially the actual application of satellite set-top box Market and the characteristics of the needs of the development and research, has a strong pertinence and high cost. At present, the domestic FTA set-top box market price competition, forcing many set-top box manufacturers have to reduce the requirements, and the use of 8 bit CPU low-end chip products, which limits the application of this kind of development more set-top box products, resulting in products of single function, large scale application of repeat stereotyped.

The crystal diagram from the IS1561 early development clearly the development thought of high performance and low cost, based on the pursuit of high performance, cost control will be listed the most important target for product development, and strive to ensure sustained competitive price of space, and the design thought embodied in the architecture, the structure design, implementation and manufacturing process until all aspects of packaging design.
