NJU6311 Quartz Crystal Oscillator IC with Selectable Divider ■GENERAL 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. ■PAKAGE OUTLINE ■FEATURES ●Operating Voltage 2.0 to 5.5V ●Maximum Oscillation Frequency 50MHz ●Low Operating Current ●High Fan-out IOH/IOL=6mA @2.5V IOH/IOL=8mA @3.3V IOH/IOL=16mA @5.0V ●Selectable Divider fo, fo/2, fo/4, fo/8, fo/16 and fo/32 ●Oscillation Stop and Output Stand-by Function ●3-State Output Buffer ●Oscillation Capacitors Cg and Cg on-die ●Package Outline Thin-Die/TVSP-10 ●C-MOS Technology ■PAD LOCATION ■SELECTABLE 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 ■COORDINATES NJU6311C-D NJU6311RB2 Thin-Die VDD IN3 IN2 IN1 CONT XT XT VSS FOUT TVSP-10 VDD IN3 IN2 IN1 FOUT CONT XT XT NC VSS No 1 Pad Name CONT X -123 Y 325 2 3 XT XT -200 -200 105 -130 4 5 6 7 8 9 VSS FOUT IN1 IN2 IN3 VDD -221 57 221 221 221 221 -346 -325 -295 -60 160 346 Starting Point:Die Center Unit[um] Die Size:0.7x0.95mm Thin-Die Thickness (-D):200±20um Pad Size:90x90um 2012/04/06 ( 1 / 5 ) NJU6311 ■BLOCK DIAGRAM XT VDD VSS Rf XT 1/2 Cg 1/2 1/2 1/2 1/2 Cd Output Selector 3-State Buffer Fout CONT IN1 IN2 IN3 ■TERMINAL 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 IN1 IN2 IN3 VDD 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 IN3 H H H H L L L L FOUT fo f0/2 fo/4 fo/8 fo/16 fo/32 2012/04/06 ( 2 / 5 ) NJU6311 ■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 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. ■ELECTRICAL CHARACTERISTICS PARAMETER Operating Voltage PARAMETER Operating Current Oscillation Stopping Current Stand-by Current Input Voltage Output Current Input Current SYMBOL VDD SYMBOL IDD ISTB Ist VIH VIL IOH IOL IIN CONDITIONS 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 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% T Output Disable time CL=15pF,RUP=10kΩ PLZ TPZL Output Enable Time CL=15pF,RUP=10kΩ Note4) Excluding input current on CONT Terminal.
