Section 4 Clock Pulse Generator (CPG)
A circuitry shown in figure 4.6 is recommended as an external circuitry around the PLL. Separate
the PLL power lines (PLLVss) and the system power lines (Vcc, Vss) at the board power supply
source, and be sure to insert bypass capacitors CB and CPB close to the pins.
