SM08-SD is an aCVi to SDI converter module.

aCVi is a video interface for transmitting SD and HD video over long distances of coaxial or twisted pair cable.

aCVi has applications in:

  • CCTV/security.
  • Industrial inspection.
  • Remote imaging.
  • Subsea imaging, ROV vehicles.
  • Pipeline inspection.
  • Vehicle cameras.
  • Information displays.
  • 3D/stereo inspection.

SM08-SD accepts 525i/625i aCVi inputs which it decodes to an SDI output. It is available either as a built and tested PCB (SB08-SD) for incorporation into your own products, or as a complete boxed module (SM08-SD).

It is compatible with the SM06-SD aCVi transmitter module.


  • No user setup and adjustment required.
  • Coaxial or twisted pair cable support (user selectable).
  • Accepts aCVi inputs in 525i or 625i video standards which it decodes to SDI outputs.
  • Automatic standard detection.
  • 5.5MHz luma bandwidth and 1.3MHz chroma bandwidth.
  • Transmitted with non-overlapping luma and chroma to avoid cable distortion issues.
  • Fully specified for transmission of >1000m of RG-59 coaxial cable.
  • Automatic cable length equalisation.
