  Full ATSC modulator - RF output  
         
  The ATSC modulator modulates an MPEG-TS DVB-SPI input into an ATSC signal in Radio Frequency (RF). ATSC modulator block diagram  
         
Description

The MVD ATSC core is a drop-in module for FPGA that includes the following functions:
  • Input data framer from DVB-SPI source (MPEG-TS flow)
  • ATSC modulator
    • Energy dispersal
    • Reed Solomon encoder
    • Interleaver
    • Trellis encoder
  • VSB modulator
  • Output for simple DAC (14 bits) or baseband outputs (2x16bits)
  Features

Ready to use ATSC modulator
  • Supported FPGA families: Spartan®-6, Virtex®-6/7, Kintex™-7, Artix™-7, Zynq™
  • Single clock
  • Robust SPI input (null packets deletion in option)
  • PCR re-stamping
  • 19.39 Mbit/s maximum input rate for 8-VSB
  • Possibility of supporting a variable symbol rate
  • Complexe baseband outputs (2 x 16 bits)
  • Single / multi channel
  • Fully synthetizable RTL VHDL design (not delivered) for easy customization
Applications

The ATSC modulator may be used in applications related to terrestrial transmission, typically at the cable head end.
