Section 10 On-Chip Oscillation Circuits
Decoupling Capacitors: Insert a laminated ceramic capacitor of 0.01 to 0.1 µF as a passive
capacitor for each V
use components with a frequency characteristic suitable for the SH3 operating frequency, as well
as a suitable capacitance value.

On-chip oscillator V
When Using a PLL Oscillator Circuit: Keep the wiring from the PLL V
pattern to the power supply pins short, and make the pattern width large, to minimize the
inductance component. Ground the oscillation stabilization capacitors C1 and C2 to V
and V
locate a wiring pattern in the vicinity. In clock mode 7, connect the EXTAL pin to V
and leave the XTAL pin open.
Notes on using pins CKIO and CKIO2 as the clock outputs: Perform board design so that the
sum of pin capacitances of the CPU and socket that are connected to pins are 50 pF or less.
