BCON Output Clock
The base clock for the BCON output is the word clock WordClk. Its frequency can range from
12 MHz to 84 MHz (settable in increments of 8, i.e. 12, 20, 28, etc.).
The word clock duty cycle is 4/7, i.e, the word clock signal is active (high) during 4/7 of each period
(
≈
57.14% of the time).
The word clock is transmitted on the separate output clock line XCLK.
The bit clock frequency f
BitClk
is not transmitted, but can be calculated. The bit clock frequency is 7
times faster than the word clock frequency:
f
BitClk
= f
WordClk
* 7
Setting the Clock Speed
You can use the pylon API to set the BCON pixel clock speed from within your application software.
The following code snippet illustrates using the API to set the clock speed:
// Set the BCON output clock speed to 84 MHz
Camera.BCONClockFrequency.SetValue(BCONClockFrequency_MHz_84);

BCON Input
The BCON input line can be used to send a trigger or other input signals to the camera.
The state of the input can be read via the camera’s control interface at any time.
