PLL Reference Window
The PLL reference window lets you change the charge pump current settings and change the PLL power down settings. The charge pump
current settings are located on the left while the power down settings are located on the right (see Figure 21).
The charge pump current options can be changed by altering the value of the CP Rset list box in the main interface window (see Figure
15). It is located in the upper right-hand corner of the PLL section (see Figure 16). Changing this resistor alters the lowest
charge pump current setting and the charge pump current increment. The CP Rset value defaults to 5.1 kΩ, which is how the AD9510
evaluation board is shipped. If you want to change this value, the software accepts Rset values between 3.1 kΩ and 11 kΩ. You must
also change the physical CP Rset resistor value on the evaluation board itself. For more information on either of these two options,
please refer to the AD9510 data sheet.

The PLL settings window (Figure 22) allows you to select which signal is presented to the status pin. For more information on any of
these outputs, please refer to the AD9510 data sheet.
