S8819W

The S8819W is an application specific integrated circuit (ASIC) designed for mobile broadband reception of digital television signals, specifically the Mobile TV broadcast. The circuit is based on the Singlechip architecture, which incorporates both analog and digital components on one chip, eliminating the need for separate components and costly packaging. The S8819W is designed as a low-cost and easy to deploy solution for the mobile sector, and it is often found in handsets, tablets and other devices. The S8819W provides high-quality mobile TV reception with low-power consumption, while making efficient use of available spectrum.

The S8819W application field includes mobile TV, broadband radio, digital audio and multimedia broadcasting, media streaming, and content delivery networks (CDNs). The circuit supports a variety of broadcast standards, such as Digital Video Broadcasting (DVB-T/H), DVB-S/S2, ATSC, and ISDB-T, allowing for flexibile configurations for various usage scenarios. The S8819W also supports multiple bands (e.g. 2.4 GHz, 5 GHz, etc.) and a frequency range from 700 MHz to 1.8 GHz. This makes it suitable for terrestrial and satellite broadcast reception.

The working principle of the S8819W is based on the digital signal processing technology. The signal received by the antenna is first converted into digital information. This information is then processed by the integrated digital processing system to extract digital signal parameters from the received signal. The extracted parameters are used to control the analog signal receiver (ASR) and also to control transmission and multiplexing of data. The process includes equalizing, synchronization, channel estimation, and frame decoding.} The output of the ASR is a digital stream of symbols, which is converted back to analog signal by a digital-to-analog converter.

The S8819W is a cost-effective solution for mobile TV reception, providing high-quality performance and supporting multiple standards. By leveraging the selection of broadcast standards, multiple x-modes of operation, and frequency range, it is suitable for a wide range of applications in the mobile sector.
