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.
