Some of them require two cables for transmission. The data counter has reached its terminal value.Ĭamera Link comes in several variants which differ in the amount of data that can be transferred.
Then registers the data out into the parallel clock domain - once The shift register catches each of the serialized bits, one at a time, To deserialize the data,Ī shift register and counter may be employed. Order to transmit or receive the serialized video. Typically a 7× clock must be generated by a PLL or SERDES block in The camera link standard calls for these 28 bits to be transmitted over 4 serializedĭifferential pairs with a serialization factor of 7. Then drives the 28 bits and a clock to the board. The receiver accepts the four LVDS data streams and LVDS clock, and The data are serialized 7:1, and the four data streams and a dedicated clock are driven over five LVDS pairs. The video sync bits are Data Valid, Frame Valid, and Line Valid. Īt a minimum, Camera Link uses 28 bits to represent up to 24 bits of pixel data and 3 bits for video sync signals, leaving one spare bit.

The standard is maintained and administered by the Automated Imaging Association or AIA, the global machine vision industry's trade group.Ĭamera Link uses one to three Channel-link transceiver chips with four links at 7 serial bits each. It was designed for the purpose of standardizing scientific and industrial video products including cameras, cables and frame grabbers. Serial communication protocol for digital camera sensorsĬamera Link is a serial communication protocol standard designed for camera interface applications based on the National Semiconductor interface Channel-link.
