ATSC Modulator
Integrated solution for the modulation of ATSC services. The system is composed by an ATSC modulator with RF output. Easily configurable through a UART serial port, allows the development of a complete and very compact modulation system.
General specifications

  • ASI and SPI TS inputs.
  • ASI and SPI TS outputs.
  • Visualization of the Input/Output TS bandwidth.
  • 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.
  • ATSC Digital Television Standard (A/53) Modulator.
  • Selectable RF power output up to -7dBm.
  • Frequency Range 0 - 300 MHz RF out through internal 1 GHz DAC.
