BU2285FV

BU2285FV Multimedia ICs Clock generator IC BU2285FV BU2285FV is an IC which produces plural clocks required for a DVD system from an external crystal oscillator and a built-in 2-channel PLL. Seven kinds of signals such as 54MHz, 27MHz and 13.5 MHz for a video clock, 33.8688MHz and 16.9342MHz for a CD clock, 33.864MHz and 18.432MHz for a DVD clock can be outputted with low jitter and high S/N. zApplications DVD System zExternal dimensions (Unit : mm) 7.8 ± 0.2 24 13 zFeatures 1) Available with seven output clock signals 2) All output low jitter (No load 30ps) High S/N (More than 50dB) 3) No need for additional components (BU2285FV has a PLL loop filter inside) 4) 3.3V signal power supply 7.6 ± 0.3 5.6 ± 0.2 1 12 1.15 ± 0.1 0.1 0.15 ± 0.1 0.65 0.22 ± 0.1 0.1 SSOP-B24 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 +125 630 Unit V V °C mW ∗An operation is not guaranteed. ∗ In case it is used at Ta=25°C or more, 6.3mW is reduced at every 1°C. ∗Radiation resistance design is not used. ∗Power dissipation is measured when BU2285FV is placed on the board. zRecommended operating conditions (Ta=25°C) Parameter Supply voltage Input "H" voltage range Input "L" voltage range Operating temperature range Output 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 ...
