13.2 External Clock Input/Output
External Clock Input
CAUTION
Only input signals that meet the specifications below. Otherwise, undesirable
signal such as excessive voltage may damage the VB8300.
The VB8300 generates waveforms by synchronizing to the internal or external clock
signal. If the clock signal is set to external (see section 5.2), apply a clock signal.
