NN6-1130™ : ASI to SPI (LVDS or TTL)


Real Time MPEG2 DVB ASI to RS 422 Converter
Standard Features

     

  • Digital TV broadcast dedicated interface Compatible with DVB and ATSC MPEG2 Transport Stream
  • Performs ASI to SPI (LVDS or TTL) conversion
  • 1x ASIinput
    1x ASI loopthrough
    1x DVB SPI (LVDS) output
    1x DVB SPI (TTL) output
  • ASI input equalization (75 ohms adapted), allowing over 100 meters cable length ASI burst (=packet) or continuous (=byte) mode equally supported
  • MPEG2 Transport stream packet size changing
    188 or 204 bytes per packet automatically detected at input
    Output framing is user defined (188, 188+16 or 204 bytes per packet)
  • PCR restamping
    Seamless insertion in any broadcasting chain
