clock generator ic BU2288FV description dimension (units : mm) features applications the BU2288FV is an ic that generates plural clocks required for dvd system from a 2-channel pll external crystal oscillator. the six kinds of signals for video and audio system are generated with low jitter. 00w130a 1) all clock signals needed for dvd can be generated by a single chip. 2) all output low jitter (no load 30psec) 3) no need for additional components. (BU2288FV has a pll loop filter inside.) 4) 3.3v single power supply 5) small ssop-b16 package ssop-b16 all dvd sets february, 2001 0.15 0. 1 0.22 0. 1 1. 15 0.1 0.65 0. 1 18 0.3min. 0. 1 6.4 0.3 9 16 4.4 0.2 5.0 0.2 absolute maximum ratings (ta=25?c) power supply voltage power dissipation operating temperature range storage temperature range parameter symbol limits unit v dd pd topr tstg 450 +70 +125 5 30 ~ 3.6 3.0 ~ ~ mw ? c ? c v ? ? derating : 4.5mw/ ? c for operation above ta=25 ? c
