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. 1.15 ± 0.1 6.4 ± 0.3 0.1 4.4 ± 0.2 5.0 ± 0.2 16 9 1 8 0.3Min.
