Clock Oscillator Characteristics (T
(a) Ceramic resonator or crystal resonator connection
Parameter
Oscillation frequency
Remarks 1. Connect the oscillator as close to the X1 and X2 pins as possible.
2. Do not wire any other signal lines in the area indicated by the broken lines.
3. For the resonator selection and oscillator constant, customers are required to either evaluate the
oscillation themselves or apply to the resonator manufacturer for evaluation.
(b) External clock input
Cautions 1. Connect the high-speed CMOS inverter as closely to the X1 pin as possible.
2. Thoroughly evaluate the matching between the V850E/IA1 and the high-speed CMOS
inverter.
