9.4 Camera clock, frequency selection
The MC130x operates with two clocks: the sensor and the pixel
clock. The sensor clock runs the sensor and thus defines the
cameras data rate. The pixel clock is responsable for the data rate
on the LVDS output. The ratio of both frequencies differ according
to selected camera mode. See:
Camera mode and maximum line
length . All frequencies are selected from an internal table with 4 x
16 entries. These are 4 camera modes x 16 select codes, 0..f
h
,
command :s<x
0
>, see chapter 6.5
The pixel clock is only dependant on the select code <x
0
> , the
sensor clock is dependant on the camera mode and select code.
Example:
Camera mode 3, selection 4:
Sensor clock = 3 MHz
Pixel clock = 15 MHz
Table 19 shows the selectable frequencies, table 20 shows the
programming codes that will be returned as a result from the
:w
command.
