FLEXMod 111

DVB-T Modulator with embedded Remultiplexer

Integrated solution for the distribution/regeneration of DVB-T services. The system is composed by a demultiplexer/multiplexer and a COFDM modulator with RF output. Easily configurable through a UART serial port, allows the development of a complete and very compact modulation system.
