Dual SPI converter (LVDS <>TTL)
NN6-4142


NN6-4142

 

 

Performs conversion of an MPEG2 transport stream from one of the electrical format of synchronous parallel interface to the other: LVDS or TTL (LVTTL). Conversion can be alternatively done in one way or the other.

 

 

 
Features

 

  • Digital TV broadcast dedicated interface
  • Compatible with DVB and ATSC MPEG2 Transport Stream

  • DVB SPI converter:
    Performs TTL to LVDS or LVDS to TTL conversion
    Note: NN6-3011 and NN6-1130 models also deal with DVB-ASI interface

  • 1x DVB-SPI (TTL) input/output

  • 1x DVB-SPI (LVDS) output/input

  • MPEG2 Transport stream packet size changing

  • 188, 188+16 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

  • Compact equipment with external power supply
