PLL input clock frequency range is 2.0 –11.5 MHz.
The usage of the output clocks is shown below:
• vt_pix_clk is used by the sensor core to control the timing of the pixel array. The

In Profile 1,2, the output clock frequencies can be calculated as:

izer. The output FIFO generates one pixel each op_pix_clk period. The pixel is either
8-bit or 10-bit depending upon the output data format, controlled by the
ccp_data_format register (R0x0112–3).
tionship between this clock frequency and the op_pix_clk frequency is dependent
upon the output data format.
