Function Prototype
u32 XRFdc_DynamicPLLConfig(XRFdc *InstancePtr, u32 Type, u32 Tile_Id, u8 Source, double RefClkFreq, double SamplingRate);Arguments
- XRFdc *InstancePtr
- Pointer to the driver instance.
- u32 Type
- RF-ADC or RF-DAC; 0 for RF-ADC and 1 for RF-DAC.
- u32 Tile_Id
- RF-ADC/RF-DAC tile number. Valid values are 0-3.
- u8 Source
- Internal PLL or external clock source.
| Macro | Description |
|---|---|
| XRFDC_EXTERNAL_CLK | For external clock |
| XRFDC_INTERNAL_PLL_CLK | For internal PLL |
- double RefClkFreq
- Reference clock frequency in MHz (FREF min to FREF max).
- double SamplingRate
- Sampling rate frequency in MHz (Fs min to Fs max).Important: For the FREF and Fs specifications see the Zynq UltraScale+ RFSoC Data Sheet: DC and AC Switching Characteristics (DS926).
Description
This API function is used for dynamic switching between the internal PLL and the external clock sources, and for configuring the internal PLL for the RF-ADCs/RF-DACs.
Return Value
XRFDC_SUCCESS
XRFDC_FAILURE
