This is an ISDB-T Modulator IP core, which provides all the necessary processing steps to modulate one, two or three transport stream into a complex I/Q signal for input to a pair of DACs, or an interpolating DAC device such as the AD9857/9957 or AD9789. Optionally the output can be selected as an IF to supply a single DAC. The design has been optimized to provide excellent performance in low-cost FPGA devices such as the Cyclone, range from Altera or the Spartan, range from Xilinx.
