Clock generator for digital still camera
BU2381FV
BU2381FV is a high-performance 3-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.
zApplications
Digital still camera
