BU2288FV

BU2288FV Multimedia ICs Clock generator IC BU2288FV 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. zApplication All DVD sets zExternal dimensions (Unit : mm) 5.0±0.2 16 9 zFeatures 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. 6.4±0.3 4.4±0.2 1 8 1.15±0.1 0.1 0.15±0.1 0.1 0.65 0.22±0.1 SSOP-B16 zAbsolute maximum ratings (Ta=25°C) Parameter Applied voltage Input voltage Storage temperature range Power dissipation Symbol VDD VIN Tstg Pd Limits −0.5 to +7.0 −0.5 to VDD+0.5 −30 to +125 450 Unit V V °C mW ∗ An operation is not guaranteed. ∗ In case it is used at Ta=25°C or more, 4.5mW is reduced at every1°C. ∗ Radiation resistance design is not used. ∗ Power dissipation is measured when BU2288FV is placed on the board. zRecommended operating conditions (Ta=25°C) Parameter Supply voltage Input "H" voltage range Input "L" voltage range Operation temperature range Output maximum load Symbol VDD VIH VIL Topr CL Min. 3.0 0.8VDD 0 −5 − Typ. − − − − − Max. 3.6 VDD 0.2VDD 70 15 Unit V V V °C pF 0.3Min. 1/6 BU2288FV Multimedia ICs zBlock diagram 27MHz XTALIN XTAL XTALOUT XTALIN=27MHz 1/6 CLK512FS 24.576MHz or 22.57...
