ETC BU2382FV

01W095A
Clock generator for digital still camera
BU2382FV
Dimension (Units : mm)
BU2382FV is a high-performance 2-channel PLL IC.
PLL circuit generates necessary clocks by inputting
standard clocks of crystal oscillator from outside.
Changing a connection of wire can generate any
clocks required for any applications of users.
Jitter and S/N characteristic has achieved almost
the same high-quality sound and vision as oscillating
module because of optimization of PLL. Frequency
can be changed by the internal dividing control.

Note) Output frequency is determined by the operation expression (Frequency divide) input to XTAL IN.
Output at 27MHz input is shown above.
Jitter is value when using Time interval analyzer with 10000 sampling.
※1) Low and high limit voltage in the schmitt trigger input Pin having hysteresis features shown in ※3 diagram.
※2) Time that output takes to stabilize in the specific frequency range after the power supply reaches to 3.0V.
※3) Make reference to the diagram.
