BU2382FV Multimedia ICs 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. zApplications Digital still camera zExternal dimensions (Unit : mm) 5.0±0.2 9 1 8 0.3Min. 16 1.15±0.1 0.1 6.4±0.3 4.4±0.2 zFeatures 1) Generate clocks for CDS, USB with standard clock input 2) No external elements required 3) Standard clocks apply to two kinds of NTSC/PAL 4) Power down control in each 2-channel PLL 5) Single power supply of 3.3V operating 6) SSOP-B16 small package 0.65 0.15±0.1 0.1 0.22±0.1 SSOP-B16 zAbsolute maximum ratings (Ta=25°C) Parameter Symbol Limits Unit Applied voltage VDD −0.5 to +7.0 V Input voltage VIN −0.5 to VDD+0.5 V Tstg −30 to +125 °C Pd 450 mW Storage temperature range Power dissipation ∗IC destruction is not occurred, however, operation can not be guaranteed. ∗Derating : 4.5mW/°C for operation above Ta=25°C. ∗This product is not designed for protection against radioactive rays. ∗Power dissipation is the rate when the IC is mounted on the board. zRecommended operating conditions (Ta=25°C) Parameter Symbol Min.

Decoupling capacitance (0.1µF) 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 100µF), 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 (<1Ω at problem high frequency) maybe used for power pin as close to BU2382FV as possible. 6/6 Appendix Notes No technical content pages of this document may be reproduced in any form or transmitted by any means without prior permission of ROHM CO.,LTD.
