Product code: CMS0041
The Commsonic DVB-T2 Modulator core provides a very efficient FPGA or ASIC implementation of all functions required to modulate the output from a MPEG-2 transport multiplexer according to the DVB-T2 ETSI EN302 755. The DVB-T2 modulator core is compliant with the specification and fully supports 1K, 2K, 4K, 8K, 16K and 32K COFDM modes. The DVB-T2 core features an integrated normal- and short-frame length BCH/LDPC encoder. L1FIELD padding, encoding and puncturing are performed automatically. Support for single or multiple PLP network configurations.
The standard output is a baseband I/Q digital pair for direct connection to a DAC. Alternative output configurations include a low IF, direct connection to standard Analog Devices Direct Digital Synthesizers (e.g. AD9857), or Analog Device RF DACs (e.g. AD9789).
Every effort has been made to keep the size of the DVB-T2 modulator to an absolute minimum in order to target the low-cost FPGA families, however this has not been at the expense of functionality. Synthesis directives are used wherever possible to remove blocks within the design which contain functionality not required for all applications.
