DVB-S/S2 Modulator with embedded Remultiplexer
Integrated solution for the distribution/regeneration of DVB-S/S2 services. The system is composed by a demultiplexer/multiplexer and a DVB-S/S2 modulator with RF output. Easily configurable through a UART serial port, allows the development of a complete and very compact modulation system.
Remultiplexer specifications

  • ASI and SPI TS inputs.
  • ASI and SPI TS outputs.
  • Automatic recognition, analysis and demultiplexing of the incoming services.
  • Visualization of the Input/Output TS bandwidth.
  • Selection and removal of unwanted services.
  • QoS (Quality of Service) function for the selected services.
  • NIT (Network Information Table) insertion for a correct Bouquet generation.
  • Automatic service monitoring and PID tracking for the desired services.
  • Supports Service-ID remapping.
  • Embedded DVB-Tables regeneration.
  • Embedded remultiplexer for the DVB-S TS reconstruction.
  • PCR restamper for a correct timing reconstruction.
  • Non-volatile memory for system configuration.
  • Easy configuration through asynchronous serial port with high-level commands.
  • No need for additional programming on power-up.
Modulator specifications:

  • QPSK DVB-S (ETSI ETS 300 421) & DVB-S2 (ETSI EN 302 307) Modulators.
  • Selectable RF power output up to -7dBm.
  • The internal oscillator can be locked to an external arbitrary clock source or to a GPS pps reference clock.
  • Support to SFN-Link (packet signature for compatibility with DVB-T SFN distribution networks).
  • Frequency range 0 - 500 MHz RF out through internal 1 GHz DAC.
  • Modulation type: QPSK DVB-S (ETSI ETS 300 421).
  • Symbol rate:1 - 32 Ms/s.
  • Constellation: QPSK.
  • FEC: 1/2, 2/3, 3/4, 5/6, 7/8.
  • Spectrum mode: Normal/Inverted.
  • PCR Restamper: Selezionabile ON/OFF.
  • SFN Compatibility: Selectable ON/OFF (packet signature for compatibility with DVB-T SFN distribution networks).
  • Output Frequency: 0-500 MHz 1 Hz Step (Internal 1Ghz DAC).
