NJU6314

NJU6314 Series High Frequency-Stability Fundamental Quartz Crystal Oscillator IC !GENERAL DESCRIPTION The NJU6314 series is a C-MOS IC for fundamental quartz crystal oscillator that consists of an oscillation amplifier, 6-stage divider and 3-state output buffer. The operating voltage is from 2.0V to 3.6V and high frequency-stability based on most suitable oscillation circuit including Cg, Cd and Rf. The 6-stage divider generates only one frequency selected of f0,f0/2,f0/4 f0/8, f0/16 f0/32 and f0/64 by internal circuits is output. The oscillation amplifier is realized very low stand-by current using NAND circuit. The 3-state output buffer is C-MOS compatible. !FEATURES "High Frequency-Stability for Operating Voltage "Operating Voltage 2.0 to 3.6V "Maximum Oscillation Frequency 60MHz "Low Operating Current "6-Stage Divider Maximum Divider f0/64 "Oscillation Stop and Output Stand-by Function "3-State Output Buffer "Oscillation Capacitors Cg and Cg on-Die "Package Outline Die/Wafer "C-MOS Technology !LINE-UP TABLE Type No. A B C D E F G FOUT f0 f0/2 f0/4 f0/8 f0/16 f0/32 f0/64 Internal Connect Connected A Line Connected B Line Connected C Line Connected D Line Connected E Line Connected F Line Connected G Line Cg/Cd 8/9pF 8/9pF 8/9pF 8/9pF 8/9pF 8/9pF 8/9pF !PACKAGE OUTLINE NJU6314XC-X !PAD LOCATION Die VDD VSS FOUT XT XT CONT !COORDINATES No 1 2 3 4 5 6 Pad Name XT XT CONT VDD VSS FOUT X -173 -173 -173 -53 67 187 Y 164 0 -164 182 182 182 NJU6314 Note) Please contact us about the divider type (B to G) of 130um die and wafer. !EXAMPLE OF PART NUMBER 1)NJU6314CW-L FOUT=f0/4, Wafer Thickness=140um 2)NJU6314AC-V FOUT= f0, Die Thickness=130um !BLOCK DIAGRAM XT Rf XT Cg Cd A CONT B C D 1/2 1/2 1/2 Starting Point: Die Center Unit[um] Chip Size: 0.6x0.6mm Die Thickness(C-V): 130±10um Die Thickness(C-L): 140±10um Wafer Thickness(W-V): 130±10um Wafer Thickness(W-L): 140±10um Pad Size: 70x70um Die Substrate: VDD Level VDD VSS 1/2 1/2 1/2 E F G 3-STATE BUFFER FOUT 2011/02/24 ( 1 / 6 ) NJU6314 Series !TERMINAL DESCRIPTION SYMBOL FUNCTION CONT Oscillation and 3-state Output Buffer Control CONT FOUT Output either one frequency selected of f0, H or OPEN f0/2,f0/4,f0/8, f0/16 f0/32 and f0/64 Note1) L Oscillation Stop and High impedance Output XT Quartz Crystal Connecting Terminals XT VSS VSS=0V FOUT Frequency Output VDD VDD=2.5V/3.3V Note1) Refer to the line-up table. !ABSOLUTE MAXIMUM RATINGS (Ta=25°C) 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 Note2) 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. Note3) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit. 2011/02/24 ( 2 / 6 ) NJU6314 Series !ELECTRICAL CHARACTERISTICS PARAMETER Operating Voltage SYMBOL VDD CONDITIONS MIN 2.0 TYP MAX 3.6 (Ta=25°C) UNIT V PARAMETER SYMBOL Operating Current IDD Oscillation Stopping Current Stand-by Current Input Voltage Output Current Input Current ISTB Ist VIH VIL IOH IOL IIN CONDITIONS A version,fosc=16MHz,CL=15pF B version,fosc=16MHz,CL=15pF C version,fosc=16MHz,CL=15pF D version,fosc=16MHz,CL=15pF E version,fosc=16MHz,CL=15pF F version,fosc=16MHz,CL=15pF G version,fosc=16MHz,CL=15pF CONT=VSS, No load CONT=XT=VSS, No load Note4) MIN (VDD=2.5V,Ta=25°C) TYP MAX UNIT 2.5 2.0 1.5 mA 1.5 1.5 1.5 1.5 1 uA uA V V mA mA uA uA uA kΩ pF MHz 50 50 2.8 4.5 2.8 4.5 55 60 5.5 9 5.5 9 200 200 % ns ns ns ns 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% Output Disable time tPLZ CL=15pF,RUP=10kΩ Output Enable Time tPZL CL=15pF,RUP=10kΩ Note4) Excluding input current on CONT Terminal.
