The APLL1 PFD frequency can operate up to 50 MHz and can be computed by Equation 1. APLL1 has programmable charge pump settings from 0 to 1500 µA in 100-µA steps. Best performance from APLL1 is achieved with a charge pump currents of 800 µA or higher.
The APLL2 PFD frequency can operate up to 150 MHz and can be computed by Equation 5 in Cascaded mode or Equation 6 in Non-cascaded mode. APLL2 has programmable charge pump settings of 1.6, 3.2, 4.8, or 6.4 mA.
