SM18 is a dual channel aCVi to HD-SDI receiver module

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

SM18 accepts two independent channels of aCVi which it decodes to two HD-SDI outputs making it ideal for stereo/3D camera video installations. It is available either as a built and tested PCB (SB18) for incorporation into your own products, or as a complete boxed module (SM18).

aCVi has applications in:

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

SM18 is a dual channel aCVi to HD-SDI converter module.

  • Two completely independent receive channels.
  • Coaxial or twisted pair cable support (user selectable).
  • Accepts 720p-25/30/50/60Hz, 1080p-24/25/30Hz and 1080i-50/60Hz video standards.
  • Automatic video standard detection.
  • HD-SDI output format.
  • 30MHz luma bandwidth and 7.5MHz chroma bandwidth (4:1:1 format)
  • Fully specified for reception of >300m (RG-59 coaxial).
  • Automatic cable length equalisation.
