| Multimedia ICs Clock generator for PD BU2190F The BU2190F is a clock generator IC for PD system drives, and uses a single crystal resonator to generate the three clock signals needed for PD system drives. *Applications PD system *Features of three different frequencies can be 1) Clock signals generated with a single attached crystal resonator. 2) Internal PLL loop filter, eliminating the need for an attached loop. 3) Single 5.0V power supply. 4) SOP 8-pin package. *Block diagram XTALI BCLK XTAL OSC XTALO 16.9344MHz PLL 1 DATA 1 1/2 59.2704MHz 16.9344MHz CLK 1 CLK 2 PLL 2 DATA 2 1/2 40.2192MHz VREF OE 1 Multimedia ICs BU2190F *Pin descriptions Pin No. 1 2 3 4 5 6 7 8 Pin name CLK2 GND XTALI XTALO BCLK CLK1 VDD OE Clock output 2 (f2 = 40.2192MHz) Ground Reference oscillation input Reference oscillation output Reference oscillation buffer output (fBCLK = 16.9344MHz) Clock output 1 (f1 = 59.2704MHz) VDD Output enable OE = H BCLK, CLK1, CLK2, enable OE = L BCLK, CLK1, disable, CLK2, enable Function Circuit B -- C C B B -- A *Absolute maximum ratings (Ta = 25C) Parameter Applied voltage Input voltage Storage temperature Power dissipation Symbol VDD VIN Tstg PD Limits - 0.5 ~ + 7.0 - 0.5 ~ VDD + 0.5 - 30 ~ + 125 Unit V V C mW 450 Does not represent guaranteed performance Reduced by 4.5mW for increase in Ta of 1C over 25C.
