bu2382fv ETC-unknow, bu2382fv Datasheet - Page 2

• Manufacturer Part Number: bu2382fv
• Description: Clock Generator For Digital Still Camera
• Manufacturer: ETC-unknow

Note) Output frequency is determined by the operation expression (Frequency divide) input to XTAL IN.
•¦ 1•j Low and high limit voltage in the schmitt trigger input Pin having hysteresis features shown in •¦ 3 diagram.
•¦ 2•j Time that output takes to stabilize in the specific frequency range after the power supply reaches to 3.0V.
•¦ 3•j Make reference to the diagram.
