Clock generator for digital still camera
BU2382FV
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.

Note) The BU2382FV is basically placed on the board. Decoupling capacitance (0.1F) need to be placed between Pin1 (VDD2) and Pin2 (VSS2), Pin5 (AVDD) and Pin6 (AVSS), Pin11 (DVSS) and Pin12 (DVDD). To obtain accurate frequency, capacitance (pF) need to be placed between Pin8 (XTAL IN) and Pin6 (AVSS). Pin7 (XTAL OUT) and Pin6 (AVSS). Tantalum capacitance (10 to 100F), ferrite beads may need to be placed to prevent power supply drop in certain board's case. To reduce high frequency noise, selected bypass capacitors (<1 at problem high frequency) maybe used for power pin as close to BU2382FV as possible.
