Outline
SNK3121A 4 in 1 mux-scrambling QAM Modulator is a high performance and cost-effective mux-scrambling QAM modulating device latest designed by Shineco Company. It provides optional interface:16 ASI input, 4 ASI input, 8 DVB-S2 and 6 DVB-S2 tuner+4 ASI input. After 4 channels multiplexing, scrambling and QAM modulating process, then it gives 4 RF output (4 adjacent frequencies by 1 RF port) and gigabit IP output. The device is characterized with high integrated level, high performance and low cost. This is very adapting to newly generation CATV broadcasting system.
