| NJU6311 PRELIMINARY Quartz Crystal Oscillator IC with Selectable Divider sGENERAL DESCRIPTION The NJU6311 is a fundamental quartz crystal oscillator, up to 50MHz. The oscillation amplifier incorporates feedback resistor and capacitors (Cg, Cd), therefore, it requires no external component expect quartz crystal, and realizes very low standby current with NAND circuit. The output frequency select 6-stage to use selectable switch IN1, IN2, and IN3, divided output are f0, f0/2, f0/4, f0/8, f0/16 and f0/32. The drivability of the 3-state output buffer is 16mA@5V, thus it can drive C-MOS load. Furthermore, the package is Thin-VSP10. sPAKAGE OUTLINE NJU6311C-D NJU6311RB2 sFEATURES qOperating Voltage 2.0 to 5.5V qMaximum Oscillation Frequency 50MHz qLow Operating Current qHigh Fan-out IOH/IOL=6mA @2.5V IOH/IOL=8mA @3.3V IOH/IOL=16mA @5.0V qSelectable Divider fo, fo/2, fo/4, fo/8, fo/16 and fo/32 qOscillation Stop and Output Stand-by Function q3-State Output Buffer qOscillation Capacitors Cg and Cg on-chip qPackage Outline Thin-Chip/TVSP-10 qC-MOS Technology sPAD LOCATION Thin-Chip CONT XT XT VSS FOUT TVSP-10 CONT XT XT NC VSS VDD IN3 IN2 IN1 FOUT VDD IN3 IN2 IN1 sSELECTABLE DIVIDER LOGIC IN1 IN2 IN3 FOUT H H H fo L H H f0/2 H L H fo/4 L L H fo/8 H H L fo/16 L H L fo/32 H L L L L L sCOORDINATES No 1 2 3 4 5 6 7 8 9 Pad Name CONT XT XT VSS FOUT IN1 IN2 IN3 VDD X -123 -200 -200 -221 57 221 221 221 221 Y 325 105 -130 -346 -325 -295 -60 160 346 Starting Point:Chip Center Unit[um] Chip Size:0.7x0.95mm Thin-Chip Thickness (-D):20020um Pad Size:90x90um 2003/08/19 ( 1 / 5 ) NJU6311 sBLOCK DIAGRAM XT Rf XT Cg Cd Output Selector 3-State Buffer Fout VDD VSS 1/2 1/2 1/2 1/2 1/2 CONT IN1 IN2 IN3 sTREMINAL DESCRIPTION SYMBOL FUNCTION CONT Oscillation and 3-state Output Buffer Control CONT FOUT Frequency Output corresponding to H or OPEN Selectable Divider L Oscillation Stop and High impedance Output XT XT VSS FOUT Quartz Crystal Connecting Terminals VSS=0V Frequency Output Selectable Divider IN1 IN2 H H L H H L L L H H L H H L L L "H" or OPEN VDD=2.5/3.3V/5.0V IN1 IN2 IN3 IN3 H H H H L L L L FOUT fo f0/2 fo/4 fo/8 fo/16 fo/32 VDD 2003/08/19 ( 2 / 5 ) NJU6311 sABSOLUTE MAXIMUM RATINGS (Ta=25C) PARAMETER SYMBOL RATING UNIT Supply Voltage VDD -0.5 to +7.0 V Input Voltage VIN VSS-0.5 to VDD+0.5 V Output Voltage VO -0.5 to VDD+0.5 V Input Current IIN mA 10 Output Current IO mA 25 Power Dissipation PD 320 (TVSP-10) mW Operating Temperature Range Topr -40 to +85 C Storage Temperature Range Tstg -55 to +125 C Note1) If the supply voltage(VDD) is less than 7.0V, the input voltage must not over the VDD level though 7.0V is limit specified. Note2) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit. Note3) The power dissipation is the maximum value at only the package. sELECTRICAL CHARACTERISTICS PARAMETER Operating Voltage SYMBOL VDD CONDITIONS MIN 2.0 TYP MAX 5.5 (Ta=25C) UNIT V PARAMETER Operating Current Oscillation Stopping Current Stand-by Current Input Voltage Output Current Input Current SYMBOL IDD ISTB Ist VIH VIL IOH IOL IIN CONDITIONS fosc=16MHz,CL=15pF CONT=IN1=IN2=IN3=VSS, No load CONT=XT=VSS, No load Note4) CONT, IN1, IN2, IN3 CONT, IN1, IN2, IN3 VOH=2.25V VOL=0.25V CONT= IN1=IN2=IN3=0.8VDD CONT= IN1=IN2=IN3=0.2VDD CONT=VSS, FOUT= VDD or VSS MIN (VDD=2.5V,Ta=25C) TYP MAX UNIT 6 mA 4 10 1 2.5 0.75 uA uA V V mA mA uA uA uA k pF MHz 50 50 2 4 2 4 55 60 4 8 4 8 200 200 % ns ns ns ns 1.75 0 6 6 7.5 1.2 12.0 2.0 0.1 3-state Off Leakage IOZ Current Feedback Resistance Rf Internal Capacitor Cg/Cd fosc=16MHz Maximum Oscillation FMAX Frequency Output Signal CL=15pF, @VDD/2 SYM Symmetry CL=30pF, @VDD/2 Output Signal Rise CL=15pF,10% to 90% tr Time CL=30pF,10% to 90% Output Signal Fall CL=15pF,90% to 10% tf Time CL=30pF,90% to 10% TPLZ Output Disable time CL=15pF,RUP=10k TPZL Output Enable Time CL=15pF,RUP=10k Note4) Excluding input current on CONT Terminal. 255 15/15 50 45 40 2003/08/19 ( 3 / 5 ) NJU6311 PARAMETER Operating Current Oscillation Stopping Current Stand-by Current Input Voltage Output Current Input Current SYMBOL IDD ISTB Ist VIH VIL IOH IOL IIN CONDITIONS fosc=16MHz,CL=30pF CONT=IN1=IN2=IN3=VSS, No load CONT=XT=VSS, No load Note4) CONT, IN1, IN2, IN3 CONT, IN1, IN2, IN3 VOH=2.97V VOL=0.33V CONT= IN1=IN2=IN3=0.8VDD CONT= IN1=IN2=IN3=0.2VDD CONT=VSS, FOUT= VDD or VSS MIN TYP 8 2.31 0 8 8 10.0 1.8 (VDD=3.3V,Ta=25C) MAX UNIT 8 mA 20 1 3.3 0.99 uA uA V V mA mA uA uA uA k pF MHz 50 50 2 4 2 4 55 55 4 8 4 8 150 150 % ns ns ns ns 15.0 3.0 0.1 3-state Off Leakage IOZ Current Feedback Resistance Rf Internal Capacitor Cg/Cd fosc=16MHz Maximum Oscillation FMAX Frequency Output Signal CL=15pF, @VDD/2 SYM Symmetry CL=30pF, @VDD/2 Output Signal Rise CL=15pF,10% to 90% tr Time CL=30pF,10% to 90% Output Signal Fall CL=15pF,90% to 10% tf Time CL=30pF,90% to 10% TPLZ Output Disable time CL=15pF,RUP=10k TPZL Output Enable Time CL=15pF,RUP=10k Note4) Excluding input current on CONT Terminal. 255 15/15 50 45 45 PARAMETER Operating Current Oscillation Stopping Current Stand-by Current Input Voltage Output Current Input Current SYMBOL IDD ISTB Ist VIH VIL IOH IOL IIN CONDITIONS fosc=16MHz,CL=50pF CONT=IN1=IN2=IN3=VSS, No load CONT=XT=VSS, No load Note4) CONT, IN1, IN2, IN3 CONT, IN1, IN2, IN3 VOH=2.97V VOL=0.33V CONT= IN1=IN2=IN3=0.8VDD CONT= IN1=IN2=IN3=0.2VDD CONT=VSS, FOUT= VDD or VSS MIN (VDD=5.0V,Ta=25C) TYP MAX UNIT 15 mA 20 40 1 5.0 1.5 uA uA V V mA mA uA uA uA k pF MHz 50 50 2 4 2 4 55 55 4 8 4 8 100 100 % ns ns ns ns 3.5 0 16 16 27.0 5.5 40.0 8.0 0.1 3-state Off Leakage IOZ Current Feedback Resistance Rf Internal Capacitor Cg/Cd fosc=16MHz Maximum Oscillation FMAX Frequency Output Signal CL=15pF, @VDD/2 SYM Symmetry CL=50pF, @VDD/2 Output Signal Rise CL=15pF,10% to 90% tr Time CL=50pF,10% to 90% Output Signal Fall CL=15pF,90% to 10% tf Time CL=50pF,90% to 10% TPLZ Output Disable time CL=15pF,RUP=10k TPZL Output Enable Time CL=15pF,RUP=10k Note4) Excluding input current on CONT Terminal. 255 15/15 50 45 45 2003/08/19 ( 4 / 5 ) NJU6311 sMEASURMENT CIRCUITS (1)Output Signal Symmetry 1000pF Pulse Generator 50 XT VDD FOUT CL=15/30/50pF VSS 1/2VDD H L (2)Output Signal Rise/Fall Time 1000pF Pulse Generator 50 XT VDD FOUT CL=15/30/50pF VSS tr tf 90% 50% 10% (3)Output Disable/Enable Time VDD XT Pulse Generator 50 CONT VSS FOUT RUP=10k CONT CL=15pF FOUT VOL 0.2VDD TPLZ 0.8VDD TPZL VOH [CAUTION] The specifications on this data book are only given for information , without any guarantee as regards either mistakes or omissions.
