 MVD Cores 
Short Desc. : DVB-T/H Modulator
Overview :
The MVD DVB-T/H modulator is a drop-in module that includes the following functions :
· Input data framer from DVB-SPI source (MPEG-TS flow)
· DVB-T/H modulator (Energy dispersal, Reed Solomon encoder, Convolutional interleaver, FEC convolution encoder, Inner interleaver, QPSK/QAM symbol mapper, Framer with pilots & TPS inserter, IFFT and guard interval insertion)
· Flexible Digital Upsampler
· Modulator for IF output
· Output for simple DAC (14 bits) or baseband outputs (2x16bits)
Features : - ETSI, DVB-T/H (EN 300 744 V1.5.1) Compliant baseband transmitter for Digital Terrestrial Television
- · The MVD modulator cores can be delivered with an Intermediate Frequency output or a RF output when using Analog Devices or Maxim RF DACs (see separate datasheet, available on request)
- · Drop-in module for Virtex-6™, Virtex-5™, Spartan-6™ and Spartan™-3/E/A FPGAs
- · Single clock (up to 140 MHz+ for Spartan-3/6™, 180 MHz+ for Virtex-5/6™)
- · Robust SPI input (discarding incorrect input packets)
- · PCR re-stamping
- · Single channel, supports hierarchical transmission
- · Configurable Convolutional Rate
- · Configurable in-depth interleaving for DVB-H
- · Programmable QPSK, 16-QAM and 64-QAM Symbol Mapping
- · Configurable support for 2k, 8k and 4k (DVB-H) OFDM modes
- · Programmable Guard Interval (1/4, 1/8, 1/16, 1/32)
- · Supports variable channel width 5MHz to 8MHz
- · Intermediate frequency output for single DAC (14 bits) or baseband outputs (2 x 16 bits)
- · Single / multi channel
- · Fully synthesizable RTL VHDL design (not delivered) for easy customization
- · Design delivered as Netlist
- · MER > 42dB
- · Carrier Suppression > 45dB
