| NJU6397 Series PRELIMINARY 3rd. Over Tone Quartz Crystal Oscillator for 135MHz sGENERAL DESCRIPTION The NJU6397 series that is a C-MOS IC for quartz crystal oscillator consists of an oscillation amplifier and 3-state output buffer. This series has three types of A, B and C. The frequency range of the A type is from 75 to 90MHz, and the B type is from 90 to 110MHz, and the C type is from 110 to 135MHz. The oscillation amplifier realizes very low oscillation stop current with NAND circuit. The 3-state output buffer is C-MOS compatible. sPACKAGE OUTLINE NJU6397XC-D 2.3 to 3.6V (See Line-up Table) IOH/IOL= 6mA @VDD=2.5V IOH/IOL= 8mA @VDD=3.3V qOscillation Stop and Output Stand-by Function q3-State Output Buffer qOscillation Capacitors Cg and Cg on-chip qPackage Outline Thin-Chip qC-MOS Technology s FEATURES qOperating Voltage qMaximum Oscillation Frequency qHigh Fan-out sPAD LOCATION Thin-Chip CONT XT XT VSS VDD FOUT sLINE-UP TABLE Type No. A B C Recommended Oscillation Frequency 75 to 90MHz 90 to 110MHz 110 to 135MHz Output Frequency f0 Cg/Cd 11/12pF 9/10pF 8/9pF sCOORDINATES No 1 2 3 4 5 8 Pad Name CONT XT XT VSS FOUT VDD X -178 -178 -178 -178 206 206 Y 231 77 -77 -231 -231 231 NJU6397 Starting Point:Chip Center Unit[um] Chip Size:0.7x0.75mm Thin-Chip Thickness:20020um Pad Size:90x90um sBLOCK DIAGRAM XT VDD VSS Rf XT Cg Cd 3 - STATE BUFFER FOUT CONT 2002/07/15 ( 1 / 5 ) NJU6397 Series sTREMINAL DESCRIPTION SYMBOL FUNCTION Oscillation and 3-state Output Buffer Control FOUT CONT CONT H or OPEN Output frequency f0 L Oscillation Stop and High impedance Output XT Quartz Crystal Connecting Terminals VSS=0V Frequency Output VDD=2.5V/3.3V XT VSS FOUT VDD 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 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 do not over the VDD level. Note2) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit. 2002/07/15 ( 2 / 5 ) NJU6397 Series sELECTRICAL CHARACTERISTICS PARAMETER Operating Voltage SYMBOL VDD CONDITIONS MIN 2.3 TYP MAX 3.6 (Ta=25C) UNIT V PARAMETER Operating Current Oscillation Stopping Current Stand-by Current Input Voltage Output Current Input Current 3-state Off Leakage Current Feedback Resistance SYMBOL IDD1 IDD2 Ist VIH VIL IOH IOL IIN IOZ Rf CONDITIONS A type, fosc=90MHz, CL=15pF B type, fosc=110MHz, CL=15pF C type, fosc=135MHz, CL=15pF CONT=VSS, No load CONT=XT=VSS, No load Note3) MIN (VDD=2.5V,Ta=25C) TYP MAX UNIT 10 20 mA 10 20 15 30 2 5 1 3.5 0.5 uA uA V V mA mA uA uA uA k VOH=2.2V VOL=0.3V CONT=0.8VDD CONT=0.2VDD CONT=VSS, FOUT= VDD or VSS A type B type C type A type, fosc=90MHz B type, fosc=110MHz C type, fosc=135MHz A type B type C type 2.0 0 6 6 7.5 1.2 12.0 2.0 0.1 Internal Capacitor Maximum Oscillation Frequency Cg/Cd 3.8 3.8 2.9 11/12 9/10 8/9 90 110 135 45 50 3 3 55 4 4 200 200 pF FMAX MHz % ns ns ns ns Output Signal SYM CL=15pF, @VDD/2 Symmetry Output Signal Rise tr CL=15pF, 10% to 90% Time Output Signal Fall tf CL=15pF, 90% to 10% Time Output Disable time TPLZ CL=15pF, RUP=10k Output Enable Time TPZL CL=15pF, RUP=10k Note3) Excluding input current on CONT Terminal. 2002/07/15 ( 3 / 5 ) NJU6397 Series PARAMETER Operating Current Oscillation Stopping Current Stand-by Current Input Voltage Output Current Input Current 3-state Off Leakage Current Feedback Resistance SYMBOL IDD1 IDD2 Ist VIH VIL IOH IOL IIN IOZ Rf CONDITIONS A type, fosc=90MHz, CL=15pF B type, fosc=110MHz, CL=15pF C type, fosc=135MHz, CL=15pF CONT=VSS, No load CONT=XT=VSS, No load Note3) 2.3 0 8 8 10.0 1.8 MIN TYP 13 13 18 (VDD=3.3V,Ta=25C) MAX UNIT 25 mA 25 35 10 1 3.3 1.0 uA uA V V mA mA uA uA uA k VOH=2.97V VOL=0.33V CONT=0.8VDD CONT=0.2VDD CONT=VSS, FOUT= VDD or VSS A type B type C type A type, fosc=90MHz B type, fosc=110MHz C type, fosc=135MHz A type B type C type 15.0 3.0 0.1 Internal Capacitor Maximum Oscillation Frequency Cg/Cd 3.8 3.8 2.9 11/12 9/10 8/9 90 110 135 45 50 2 2 55 3 3 150 150 pF FMAX MHz % ns ns ns ns Output Signal SYM CL=15pF, @VDD/2 Symmetry Output Signal Rise tr CL=15pF, 10% to 90% Time Output Signal Fall tf CL=15pF, 90% to 10% Time Output Disable time TPLZ CL=15pF, RUP=10k Output Enable Time TPZL CL=15pF, RUP=10k Note3) Excluding input current on CONT Terminal. 2002/07/15 ( 4 / 5 ) NJU6397 Series sMEASURMENT CIRCUITS (1)Output Signal Symmetry(CL=15pF) 1000pF Pulse Generator 50 XT VDD FOUT CL=15pF VSS 1/2VDD H L (2)Output Signal Rise/Fall Time(CL=15pF) 1000pF Pulse Generator 50 XT VDD FOUT CL=15pF VSS tr tf 90% 50% 10% (3)Output Disable/Enable Time(CL=15pF,RUP=10k) 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.
