ORCA Series 4 FPGAs
Phase-Locked Loops (continued)
Table 29. STS-3/STM-1 PLL2 Specications
All Series 4 PLLs operate from the VDD33 power supply. Care needs to be taken during board layout to properly iso-
late and lter this power supply. More information about the PLLs is available in the Series 4 FPGA PLL Elements
application note. The location of all eight PLLs on Series 4 FPGAs is shown in Figure 32 and Table 30.
