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 a Fractional, Left/Right, Top/Bottom, or an
LVDS PLL. This option is not applicable for all device families.
# PLL Blocks Enter the number of PLL blocks with the same specific output
frequency and VCO frequency combination.
# DPA Buses Enter the number of DPA buses in use. DPA is only available for LVDS
PLLs. This option is not applicable for all device families.
Output Freq (MHz) Enter the maximum output frequency of the PLL (in MHz). The
maximum output frequency is reported in the Output Frequency
column of the Quartus II Compilation Report. In the Compilation
Report, select Fitter and click Resource Section. Select PLL Usage and
click Output Frequency.
VCO Freq (MHz) Enter the internal VCO operating frequency for this module. The
LVDS PLL drives the LVDS clock tree and DPA bus at this frequency.
This frequency includes the VCO post scale counter.
Total Power (W) Shows the estimated combined power for V
CCA
and V
CCD
(in watts),
based on the maximum output frequency and the VCO frequency you
entered. This value is automatically calculated.
User Comments Enter any comments. This is an optional entry.
