4.7. Cyclone® 10 GX EPE - PLL Worksheet
For Cyclone® 10 GX devices, the supported PLL types are IOPLL, fPLL, ATX PLL, and CMU PLL.
|Specify a name for the PLL in this column. This is an optional value.
|Select whether the PLL is an IOPLL, fPLL, ATX PLL, or CMU PLL.
|# PLL Blocks
|Enter the number of PLL blocks with the same combination of parameters.
|Enter the number of counters of the PLL. For fPLL, this includes C counter, L counter, and feedback. This field is not applicable for ATX PLLs and CMU PLLs.
|VCCR_GXB and VCCT_GXB Voltage
|Specify the voltage of the VCCR_GXB and VCCT_GXB rails. This field is not applicable for I/O PLLs.
|Output Freq (MHz)
|Specify the output frequency for CMU and ATX PLLs.
|VCO Freq (MHz)
|Specify the internal VCO operating frequency for fPLLs and I/O PLLs. When using an fPLL as a transmitter PLL for XCVR channels, the VCO frequency has to be such that the required fPLL output frequency can be achieved using a legal value of the counter used for HSSI clock output.
|Total Power (W)
|Shows the total estimated power for this row (in W).
|Enter any comments. This is an optional entry.
