DVB-T/H Modulator - RF output with AD9789 DAC

Overview

The MVD DVB-T/H modulator is a drop-in module for FPGA that includes the following functions :
• Input data framer from Microprocessor, DVB-SPI source (MPEG-TS flow)
• DVB-T modulator◦Energy dispersal
◦ Reed Solomon encoder
◦ Convolutional interleaver
◦ FEC convolution encoder
◦ Inner interleaver
◦ QPSK/QAM symbol mapper
◦ Framer with pilots & TPS inserter
◦ IFFT and guard interval insertion
• Low pass filter
• Output for complex DAC (2 x 16 bits)
