4 in 1 mux-scrambling encoder modulator

  NDS3343D 4 in 1 mux-scrambling encoder modulator is a high performance and cost-effective mux-scrambling encoding QAM modulator. It has multiple input ports optional. After encoding, multiplexing, scrambling and QAM modulating process, then it gives RF output. To meet customers’ various requirements, this device is also equipped with Tuner input to extend the signal source. Its pluggable structure design greatly facilitates the change of modules (demodulator or encoder etc) as needed.

The device is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation CATV broadcasting system.
