RTL2830
DVB-T COFDM Demodulator
 
General Description
The RTL2830 is a high-performance DVB-T COFDM demodulator that integrates a COFDM demodulator, FEC decoder, and de-interleavers, and complies with NorDig 1.02 and ETS 300 744 (ETSI Specification).
 
The RTL2830 supports tuners at IF (Intermediate Frequency) (36MHz/44MHz) or low-IF (4.57MHz) input using a 28.8MHz or 25MHz crystal. Embedded with an advanced ADC, the RTL2830 features high stability in portable reception. Via a two-wire interface, the output transport stream supports parallel and serial interfaces, providing great flexibility for implementation with different back-end ICs or USB bridge ICs.
 
The state-of-the-art RTL2830 features Realtek proprietary algorithms (patent-pending), including superior channel estimation, co-channel interface rejection, long echo channel reception, and impulse noise cancellation, and provides an ideal solution for a wide range of applications for PC-TV, portable TV, Set-Top Box, TV tuner module etc.
