4.3. Parameters Settings for Generating ALTPLL IP Core
For more information about all ALTPLL parameters, refer to the related information.
Tab | Parameter | Setting |
---|---|---|
Parameter Settings > General/Modes | What is the frequency of the inclk0 input? | Specify the input frequency to the PLL. |
Parameter Settings > Inputs/Lock | Create an 'areset' input to asynchronously reset the PLL | Turn off this option. |
Create 'locked' output | Turn on this option. You need to connect this signal to the adc_pll_locked port of the Modular ADC Core or Modular Dual ADC Core IP core. |
|
Output Clocks > clk c0 | Use this clock | Turn on this option. |
Enter output clock frequency | Specify an output frequency of 2, 10, 20, 40, or 80 MHz. You can specify any of these frequencies. The ADC block runs at 1 MHz internally but it contains a clock divider that can further divide the clock by a factor of 2, 10, 20, 40, and 80. Use this same frequency value in your Modular ADC Core or Modular Dual ADC Core IP core. You need to connect this signal to the adc_pll_clock port of the Modular ADC Core or Modular Dual ADC Core IP core. Different ADC sampling rates support different clock frequencies. For a valid sampling rate and clock frequency combination, refer to the related information. |
