  DVB-T2 modulator  
         
  The DVB-T2 modulator modulates an MPEG-TS DVB-SPI input into a DVB-T2 output. DVB-T2 modulator block diagram  
         
Description

The DVB-T2 core allows the transmission of an MPEG-TS data stream to a digital to analog converter in base band, IF or RF mode.
The core is DVB T2 (ETSI EN 302 755 V1.1.1) compliant and support most of the standard parameters settings.

The core was developed in RTL VHDL in order to be implemented in any kind of FPGA programmable logic components.

The MPEG-TS input data stream comes from a Synchronous Parallel Interface (SPI). The core output is natively designed for AD9789 but, in addition to our optional UPSAMPLER or UPCONVERTER module, can drive a simple or a complex DAC (I and Q with two 16-bit outputs) in IF or RF application.

MVD delivers the core as netlist format according to targeted FPGA family.

Features
  • ETSI, DVB-T2 (EN 302 755 V1.1.1) compliant baseband transmitter for second generation Digital Terrestrial Television broadcasting system
  • The MVD DVB-T2 modulator core is delivered for baseband output to be natively connected to AD9789 DAC from Analog Device but can be used in Intermediate Frequency application or in RF application when respectively connected to our UPSAMPLER or our UPCONVERTER core (for Analog Devices (AD9739A) or Maxim RF DACs (MAX5881)).

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.
