4.7. Cyclone® 10 GX EPE - PLL Worksheet

Each row in the PLL worksheet of the Early Power Estimator (EPE) for Cyclone® 10 GX represents one or more PLLs in the device.

For Cyclone® 10 GX devices, the supported PLL types are IOPLL, fPLL, ATX PLL, and CMU PLL.

Table 12.  PLL Worksheet Information
Column Heading Description
Module Specify a name for the PLL in this column. This is an optional value.
PLL Type 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.
# Counters 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).
User Comments Enter any comments. This is an optional entry.

For more information about the PLLs available in Cyclone® 10 GX devices, refer to the Clock Networks and PLLs chapter of the Cyclone® 10 GX Device Handbook.
