Configuration Tab
The Configuration Tab lists all user accessible attributes with default values set. Upon completion, clicking Gener-
ate will generate source and constraint files. Users may choose to use the .lpc file to load parameters.
Configuration Modes
There are two modes that can be used to configure the PLL in the Configuration Tab, Frequency Mode and Divider
Mode.
Frequency Mode: In this mode, the user enters input and output clock frequencies and the software calculates the
divider settings. If the output frequency entered is not achievable the nearest frequency will be displayed in the
‘Actual’ text box. After input and output frequencies are entered, clicking the Calculate button will display the
divider values.
Divider Mode: In this mode, the user sets the divider settings with input frequency. Users must choose the CLKOP
Divider value to maximize the f
and achieve optimum PLL performance. After input frequency and divider set-
VCO
tings are set, clicking the Calculate button will display the frequencies. Figure 9-9 shows the Configuration Tab.
