General Description

The MW_ATSC modulator core performs the digital baseband function for the transmission side of new generation Digital Video Broadcasting in the United States. It implements the framing functions as defined by A/53: ATSC Digital Television Standard, Parts 1-6, 2007. The MW_ATSC core is designed to achieve high performance for a single chip FPGA based design, including control and status management. 8VSB is used as the terrestrial transmission format. The modulator using eight discrete amplitude modulation levels, that are assigned eight different symbol values, to convey the MPEG compressed transport stream. It supports a payload data rate of 19.39 Mb/s in a 6 MHz channel. The input to the transmission subsystem from the transport subsystem is a data stream comprised of 188 byte MPEG-2. Internal 20-bit architecture for high level MER and BER performances is provided. A larger capability could be obtained using additional FPGA resources. FPGA netlist only or complete design environment package are deliverable. The core was developed in Vivado tool, written in HDL code.
