2.1.5 Basic Flow

The following flow is recommended to configure the clock generated by the selected CCC for basic use cases:

  1. Select the number of desired output clocks (up to four).
  2. Set the required output frequency, for each selected output clock.
  3. Configure the CCC/PLL reference clock source and frequency. For an oscillator input, a 50 MHz oscillator is available.

In basic configuration, the PLL is always used to generate the output frequency. The feedback of the PLL is internal to the CCC. Click the Basic tab of the RTG4 FCCC with Enhanced PLL Calibration Configurator for the basic configuration of the selected CCC.

Actual output frequencies achieved by the RTG4 FCCC with Enhanced PLL Calibration Configurator are shown in the Actual column.
