DVB-C/J83 Mod.

General Description

The MW_DVBC modulator core performs the digital baseband functionality for the transmission side of Digital Video Broadcasting Cable link. The modulator core implements the framing functions as defined by ETSI EN 300 429 V1.2.1 (1998-04). It is configurable to supports all several configurations regard to constellation, 16QAM, 32QAM,64QAM, 128QAM and 256QAM. Microblaze or external processor interface,with status and control registers, is available for controlling and managing the core. TS over IP, for IP based contribution, or ASI contribution are available. A direct interface 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.
