• Manufacturer Part Number: BU3076HFV
• Description: Clock Generator
• Manufacturer: ROHM Co. Ltd.

The following parameters represent design guaranteed performance.
BU7322HFV（Ta=25℃, VDD=3.3V, Crystal frequency=27.0000MHz, unless otherwise specified.）
Note) The output frequency is determined by the arithmetic (frequency division) expression of a frequency input to IN.
BU7325HFV （ Ta=25 ℃ , VDD=3.3V, Crystal frequency=27.0000MHz, unless otherwise specified. ）
The following parameters represent design guaranteed performance.

Common to BU3071HFV, BU3072HFV, BU3073HFV, BU3076HFV, BU7322HFV, BU7325HFV
∗1
This parameter represents standard deviation (=1σ) on cycle distribution data at the time when the output clock cycles are
sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
∗2
This parameter represents a maximum distribution width on cycle distribution data at the time when the output clock cycles are
sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
∗3
This parameter represents elapsed time after power supply turns ON to reach a voltage of 3.0 V, after the system is switched from
Power-Down state to normal operation state, or after the output frequency is switched, until it is stabilized at a specified frequency,
respectively.
