DVB-T/H Modulator

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)

• 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 Xilinx Spartan-6, Virtex-6, Artix-7, Kintex-7, Virtex-7, Zynq 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

• The MVD DVB-T/H modulator may be used in applications related to terrestrial transmission, typically at the head end.
