Program the R (reference) divider by clicking the
R DIVIDER box at the top of the main window. Set
the desired value and click OK (see Figure 12).
Program the N (feedback) divider by clicking the
N DIVIDER box at top of the main window. Set the
desired value and click OK. For the example, N = 200
can use 8/9 dual modulus mode with A = 0 and B = 25.
Set the charge pump current by clicking the CHARGE
PUMP box in the upper right corner of the main window,
and then click OK.
Note that if the desired configuration has the phase
detector frequency above 50 MHz, an antibacklash pulse
width of 1.3 ns may work better. This setting is accessed by
clicking the PFD button to the left of the CHARGE PUMP
box. However, this setting normally does not need to be
modified.
