| 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) 5.0 0.2 1.15 0.1 6.4 0.3 0.1 4.4 0.2 16 9 1 8 0.15 0.1 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 0.65 0.1 0.22 0.1 SSOP-B16 Applications DVD sets Absolute Maximum Ratings (Ta=25C) Parameter Maximum applied voltage Power dissipation Operating temperature range Storage temperature range Symbol VDD Pd Topr Tstg -10 -30 -0.5 Limits Unit V mW ~ 7.0 450 * ~ ~ +70 +125 C C *Derating :4.5mW/C for operation above Ta=25C Recommended Operating Conditions (Ta=25C) Parameter Power supply voltage Symbol VDD Min. 3.0 Typ. 3.3 Max. 3.6 Unit V December, 2001 0.3Min.
