Applications

• The MVD DVB-T2 modulator may be used to broadcast a high rate stream (HD or 3D for example) or a multiplexed stream with many services.
• The standard allows choosing from a strongly robust stream to a very high data bitrate stream.

Deliverables

• Datasheet
• Netlist for core generation
• VHDL top file
• VHDL source code: can be delivered as an option under NDA and other specific clauses
