The case of the failing Camera Link cables
December 18, 2007
Why were Camera Link cables tested at 85 MHz failing in 80-MHz camera applications? That’s a situation that puzzled cable manufacturers such as
Components Express and frame-grabber makers such as
BitFlow. The problem seems to center on different test methods: eye-diagram measurements using an oscilloscope and bit-error-rate measurements using a frame-grabber and camera emulator. Components Express enlisted the help of camera-emulator maker
Vivid Engineering to develop a test bed to investigate the problem. The companies presented their findings to the Automated Imaging Association’s
Camera Link committee, which formed a cable subcommittee to consider the issue. The subcommittee may revise the eye-pattern test specified in Camera Link standard based on the data from the bit-error-rate tests when it meets in June. AIA contributing editor Winn Hardin has the
