DVB-C Modulator J.83 Annex A/C Core

Overview

The MVD DVB-C core is a drop-in module that includes the following functions :
- Input data framer from DVB-SPI source (MPEG-TS flow)
- J83AC modulator
- Energy dispersal
- Reed-Solomon encoder
- Interleaver
- QAM symbol mapper)
- Output for complex DAC (2 x 8 bits)

The MVD DVB-C 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))
