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)

Key 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 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
