| Abstract: | Digital TV tuner is an important part in the TV set top box, and it is an upgrade of analogue TV, which makes it possible for analogue TV to receive digital TV programs, also it has all broadcasting and multimedia application function. This paper introduced the basic components, operating process and operating principle of digital satellite Set-Top-Box. It laid emphasis on the internal components and relative parameters of the single chip tuner LW10039 which adopts the design of Zero IF. Also the paper gave a detailed analysis of the operating principle and advantages of every component integrated in LW10039, displayed the characteristics of this chip. Finally it showed the current state and developing trend of digital satellite Set-Top-Box. |
