NJU6315 Series 0.9V Operation Fundamental Quartz Crystal Oscillator IC !GENERAL DESCRIPTION The NJU6315 series is C-MOS quartz crystal oscillator IC for fundamental (up to 50MHz) oscillation. The operating voltage is from 0.9V to 3.3V, and the pad layout is suitable for wire bonding mount of existing-sized ceramic package. The 5-stage divider generates only one frequency selected of f0, f0/2,f0/4 f0/8, f0/16 and f0/32 by internal circuits is output. The oscillation amplifier is realized very low stand-by current using NAND circuit. Furthermore, The 3-state output buffer is C-MOS compatible. !PACKAGE OUTLINE !FEATURES "Operating Voltage 0.9 to 3.3V "Maximum Oscillation Frequency 50MHz "Low Operating Current "5-Stage Divider Maximum Divider f0/32 "Oscillation Stop and Output Stand-by Function "3-State Output Buffer "Oscillation Capacitors Cg and Cg on-Die "Package Outline Thin-Die "C-MOS Technology !PAD LOCATION !LINE-UP TABLE !COORDINATES Type No. FOUT A f0 B* f0/2 C* f0/4 NJU6315 D* f0/8 E* f0/16 F* f0/32 * Under Development Internal Connect Connected A Line Connected B Line Connected C Line Connected D Line Connected E Line Connected F Line NJU6315XC-L Thin-Die CONT XTI XTO VSS Cg/Cd 9/10pF 9/10pF 9/10pF 9/10pF 9/10pF 9/10pF VDD FOUT No Pad Name X Y 1 CONT -178 231 2 XTI -178 77 3 XTO -178 -77 4 VSS -178 -231 5 FOUT 206 -231 6 VDD 206 231 Starting Point: Die Center Unit[um] Die Size: 0.7x0.75mm Die Thickness (C-L): 140±10um Wafer Thickness (W-L): 140±10um Pad size: 90x90um Die Substrate: VDD level !EXAMPLE OF PART NUMBER 1)NJU6315AW-L FOUT=f0, Wafer Thickness=140um 2)NJU6315CC-L FOUT= f0/4, Die Thickness=140um !BLOCK DIAGRAM VDD XTO VSS Rf XTI 1/2 Cg 1/2 1/2 1/2 1/2 Cd A B C D E F 3-STATE BUFFER FOUT CONT 2010/07/28 ( 1 / 4 ) NJU6315 Series !TERMINAL DESCRIPTION SYMBOL FUNCTION Oscillation and 3-state Output Buffer Control CONT FOUT Output either one frequency selected of f0, CONT H or OPEN f0/2,f0/4,f0/8, f0/16 and f0/32 Note1) L Oscillation Stop and High impedance Output XTI Quartz Crystal Connecting Terminals XTO VSS VSS=0V FOUT Frequency Output VDD VDD=1.2V/1.5V Note1) Refer to the line-up table.

Note3) Decupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit. Note4) Please handle with care because of sensitive to ESD. 2010/07/28 ( 2 / 4 ) NJU6315 Series !ELECTRICAL CHARACTERISTICS PARAMETER Operating Voltage PARAMETER Operating Current Oscillation Stopping Current Input Voltage Output Current Input Current 3-state Off Leakage Current Feedback Resistance Internal Capacitor Oscillation Frequency SYMBOL VDD SYMBOL IDD ISTB VIH VIL IOH IOL IIN IOZ CONDITIONS 8MHz≤fosc≤40MHz fosc≤50MHz CONDITIONS A version, f0=50MHz, CL=15pF MIN 0.9 1.1 MIN CONT=VSS, No load VOH=1.08V VOL=0.12V CONT=0.8VDD CONT=0.2VDD TYP MAX 3.3 3.3 (Ta=25°C) UNIT V (VDD=1.2V, Ta=25°C) TYP MAX UNIT 2.8 4.0 mA 1 0.84 0 2 2 3.0 0.5 CONT=VSS, FOUT= VDD or VSS 3 uA 1.2 0.36 4.5 0.7 V V mA mA uA uA ±0.1 uA Rf 255 kΩ Cg/Cd fosc=16MHz 9/10 pF fMAX Recommendation Note5) 50 MHz Output Signal Symmetry SYM CL=15pF, @VDD/2 45 50 55 % Output Signal Rise Time tr CL=15pF,10% to 90% 3 6 ns Output Signal Fall Time tf CL=15pF,90% to 10% 3 6 ns Output Disable time tPLZ CL=15pF,RUP=10kΩ 250 ns Output Enable Time tPZL CL=15pF,RUP=10kΩ 250 ns Note5) The oscillation frequency range has used NJRC’s standard crystal for measurement.
