01W031A Clock generator IC BU2286FV Description BU2286FV is an IC that generates multiple clocks from the built-in 2ch PLL of the external crystal oscillator used for DVD system. This IC creates six kinds of signals for video, audio, and low jitter system. Dimension (Units : mm) Features 1) Can generate clock signals needed for DVD by a single chip 2) All output low jitter (No load 30ps) 3) Built-in PLL loop filter, No external components needed 4) 3.3V single power supply 5) Small SSOP-B16 package 16 9 1 8 0.3Min. 1.15 ± 0.1 6.4 ± 0.3 0.1 4.4 ± 0.2 5.0 ± 0.2 0.65 0.15 ± 0.1 0.1 0.22 ± 0.1 SSOP-B16 Applications DVD sets Absolute Maximum Ratings (Ta=25°C) Parameter Limits Symbol Maximum applied voltage VDD Power dissipation Pd –0.5 Operating temperature range Topr –10 Storage temperature range Tstg –30 Unit ~ 7.0 450 * ~ ~ V mW +70 +125 °C °C *Derating :4.5mW/°C for operation above Ta=25°C Recommended Operating Conditions (Ta=25°C) Parameter Power supply voltage Symbol Min.
