High-performance RF receiver chip RDA5880 chip using CMOS technology, QFN32 5 x 5 mm package, off-chip device is minimal, with highly integrated features. Support the AGC mode, able to support the current mainstream digital TV broadcasting standard (DVB-T, DVB-C, ATSC, DMB-T / H, CMMB, etc.) as well as analog TV standards, support for multi-band band III 174M-240M , VHF band 470M-870M.
RDA5880 is a chip designed specifically for China's terrestrial digital TV market, and further strengthen the characteristics of various products to enhance the possibility of the RDA5880 used in mobile systems. Within RDA5880 piece of powerful, high-performance (noise figure less than 5 dB), low power consumption (less than 150mA), can be widely used in notebook computers, of MP3/MP4, high-end mobile phone, PMP, PDA, car entertainment, navigation systems, digital the portable terminal of the camera, etc., can also be used in set-top box, to meet the user for a long time, to directly watch the digital terrestrial television broadcasting needs.
In addition to the high level of integration features, RDA5880 also has a very good performance. System noise figure less than 5 dB (including front-end band III and VHF Band crossover network), good sensitivity to ensure the application of the terminal can receive terrestrial digital TV programs even in the distance, the signal is weak; signal signal-to-noise more than 30dB in the application to meet the demodulation requirements of QAM256, RDA5880 also extremely low power consumption of a product, power consumption is less than 150mA, extended battery life; the chip performance in anti-interference ability to meet NorDig1 .0.3 standards to ensure that the received sound, clear, smooth video. |
