Grabber is EEM module dedicated to cooperate with typical scientific EMCCD cameras with CameraLink port. Its output is already digitized pixel data at high speed and low latency before and independent of it being transferred over USB or Ethernet.

A Base CameraLink has a clock, four data, four control and two serial communications lines. The clock and data lines carry the frame data. They also carry FVAL/DVAL/LVAL (frame, data, line valid flags to describe the shape of the frame and validity of the data). Base transfers 28 bits (4 control and 24 data) per clock cycle. Maximum clock frequency is 85 MHz, line rate on the data lines is 85 MHz * 7 = 595 MHz. Signal standard is LVDS. The extension module should be a dumb adapter.

Medium or Full CameraLinks use more clock and data lines.

Grabber was designed to cooperate especially with Andor‘s EMCCD cameras.
