GENERAL DESCRIPTION

SAA7219 overview

The device is part of a comprehensive source decoding kit which contains all the hardware and software required to receive and decode MPEG-2 transport streams, including descrambling, demultiplexing. In addition, it includes a PR3930 core which is a 32-bit MIPS RISC-based CPU core supporting the MIPS 16 instruction set to reduce memory requirements and several peripheral interfaces such as UARTs, I2C-bus units, an IEC 1883, and an IEEE 1284 (Centronics) interface. The SAA7219 is therefore capable of performing all controller tasks in digital television receiver applications such as set-top boxes. Furthermore, the SAA7219 is compliant to DVB and MULTI2 standards.

FEATURES
