02W139A Clock generator for DVD BU2362FV Dimension (Unit : mm) 5.0 ± 0.2 Features 16 9 1 8 0.3Min. 1.15 ± 0.1 6.4 ± 0.3 0.1 4.4 ± 0.2 Description BU2362FV is a high-performance 2-channel PLL integrated Circuit. PLL circuit generates necessary clocks by inputting standard clocks of crystal oscillator from outside. Frequency can be changed by the internal dividing control. 0.15 ± 0.1 0.1 0.65 0.22 ± 0.1 SSOP-B16 1) Generate Sound clock (44.1k, 48k) from basic video clock 2) No external element required for PLL 3) 3.3V single power supply (2.7V~3.6V operation) 4) –25˚C ~ 85˚C operation 5) SSOP-B16 package Applications DVD-P, DVD-R, DVD-R/W, DVC DVD car navigation (Expanded operating temperature range for car navigation: –25˚C ~ 85˚C) DVD camcoder (Low power operation (3.0V±0.3V) for portable appliances) Absolute Maximum Ratings (Ta=25˚C) Parameter Applied voltage Input voltage Storage temperature range Limits Symbol VDD -0.5 VIN Tstg -0.5 Power dissipation Pd -30 ~ ~ ~ Unit +7.0 V VDD+0.5 V +125 ˚C 450 mW ∗Derating : 4.5mW/˚C for operation above Ta=25˚C December, 2002 Recommended Operating Conditions (Ta=25˚C) Symbol Min.

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, some capacitance( µF) need to be placed nearly between pin7 and GND, pin8 and GND. In certain condition of the board, the electrolytic capacitor may need to be placed between power supply and GND. As a measure against EMI, it is effective to place ferrite beads on the starting point of power supplied from the board to BU2362FV, and to use selected bypass capacitor(1Ω or less) between power supply and GND that can reduce high frequency noise.
