Manufacturer:XILINX Description:The value of the load capacitors can be roughly determined by the formula C = 2(CL - 6) where C is the load capacitor connected to X1 and X2, and CL is the specified value of the load capacitance for the crystal. A typical crystal CL is 18 pF, so C = 2(18 - 6) = 24 pF. Because these capacitors adjust the stray capacitance of the PCB, check the output frequency using your final layout to see if the value of C should be changed. |
