3.4 Clocking Structure

The following figure shows the clocking structure of the design.

  • PF_CCC generates 125 MHz fabric clock from 148.5 MHz on-board reference clock. This generated clock is used to drive FIC0 and FIC1 interface of the MSS. This also acts as the AXI4-Lite interface clock.
  • The on-board 27 MHz Oscillator on the camera module is used as a reference clock for IOD in the IMX334 block. The CCC inside the IMX334 uses reference clock from IOD and generates 170 MHz clock.
