5.5 Pulse Generator
The EL-2800-CXP has a frequency divider using the pixel clock as the basic clock and four pulse
generators. In each Pulse Generator, various Clear settings are connected to GPIO. The following
shows Pulse Generator default settings.
Table - 10 Pulse Generator default settings
5.5.1 Clock Pre-scaler
Clock pre-scaler (Divide Value) can set the dividing value of the frequency divider (12-bit
length) and the pixel clock is used for this. Four built-in pulse generators work by the same
clock. In the EL-2800M/C-PMCL, the pixel clock is 108 MHz.
5.5.2 Pulse Generator Selector
This is where you select one of the 4 pulse generators in order to set or modify its parameters.

Note:]
When Pulse
Generator Repeat Count is set to “0”, the camera is operating in Free Running mode.
However, based on the above default settings (Length=1, Start Point=0 and End Point=1), Pulse Generator stops at
High output. Therefore, if Start Point=0 and End Point=1 are configured, Length should be
“

”
as the minimum active
width.
