sysCLOCK PLL Design and Usage Guide
Figure 11-7. Configuration Tab
Divider Mode: In this mode, the user sets the input frequency and divider settings. It is assumed the user is famil-
iar with the PLL operation. The user must choose the CLKOP Divider value to maximize the f
to achieve opti-
VCO
mum PLL performance. After input frequency and divider settings are set, clicking the ‘Calculate’ button will display
the output frequencies. If the divider settings are out of the PLL specification, the software will generate an error.
