Pixel Clock

Pixel Clock connector locations

When the digital synchronization is used, the camera channel generates a clock signal. The video signal is synchronized with this clock signal.

The GND connection is used in case of single-ended clock sensing.

Non-inverted differential pixel clock (default setting)

This configuration is used with a non-inverted differential pixel clock signal. The pixel clock is applied to CK+ and CK-.

The MultiCam parameter JumperCK is set to CKDPOS and the electrical equivalent schematics is:

Alpha2PxlClkDiffInputLine

Inverted differential pixel clock

This configuration is used with an inverted differential pixel clock signal. The pixel clock is applied to CK+ and CK-.

The MultiCam parameter JumperCK is set to CKDNEG and the electrical equivalent schematics is:

Alpha2PxlClkDiffCrossedInputLine

Equivalent schematics for CKDNEG

Non-inverted single-ended pixel clock

This configuration is used with a non-inverted single-ended pixel clock signal. The pixel clock is applied to CK+ and GND.

The MultiCam parameter JumperCK is set to CKSPOS and the electrical equivalent schematics is:

Alpha2PxlClkSingleEndedInputLine

Equivalent schematics for CKSPOS

Inverted single-ended pixel clock

This configuration is used with an inverted single-ended pixel clock signal. The pixel clock is applied to CK- and GND.

The MultiCam parameter JumperCK is set to CKSNEG and the electrical equivalent schematics is:

Alpha2PxlClkSingleEndedCrossedInputLine

Equivalent schematics for CKSNEG

No pixel clock

If the camera does not use a pixel clock, the CK jumper block is empty with no jumper installed.

The MultiCam parameter JumperCK is set to EMPTY and the electrical equivalent schematics is:
