ISDB-T Modulator
The MVD ISDB-T core is a drop-in module that includes the following functions :
• Input data framer from DVB-SPI source (MPEG-TS flow)
• ISDB-T modulator (Reed-Solomon encoder, Energy dispersal, Convolutional interleaver, FEC convolution encoder, QAM symbol mapper, Time & Frequency Interleaver, IFFT)
• Low Pass Filter
• Output for complex DAC (2 x 16 bits)
The MVD ISDB-T modulator core is delivered for baseband output to be natively connected to AD9789 DAC from Analog Devices but can be used in Intermediate Frequency application (for Analog Devices (AD9744)) or in RF application when respectively connected to our UPSAMPLER or our UPCONVERTER core (for Analog Devices (AD9739A) or Maxim RF DACs (MAX5881)).
