MW_DVBTH Modulator Core


General Description

The MW_DVBTH modulator core performs the digital baseband functionality for the transmission side of Digital Video Broadcasting Terrestrial link. The modulator core implements the framing functions as defined by ETSI EN 300 744 V1.5.1 (2004-11).
The modulator core is deliverable in DVB-T and DVB-H functionality, ASI based contribution. It is configurable to supports all several configurations regard to constellation, 4QAM, 16QAM and 64QAM, code rate, 1/2, 2/3, 3/4, 5/6 and 7/8, guard interval, 1/32, 1/16, 1/8 and 1/4, 2K-4K-8K. A reduced 2k compact version of the DVB-T/H core is deliverable. Microblaze or external processor interface, with status and control registers, is available for controlling and managing the core. External memories (SDRAM and DDR) are used to support SFN functionality. A dedicated interface is perfomed. TS over IP is available, for IP based contribution. A direct interfave with Analog Devices AD9789, covering VHF-UHF bands is available. Internal 20-bit architecture for high level MER and BER performances.
FPGA netlist only or complete design environment package are deliverable.
