NJU6214 Series Small-Sized 1.8V Operating Voltage Fundamental Quartz Crystal Oscillator IC !GENERAL DESCRIPTION The NJU6214 series is a C-MOS quartz crystal oscillator IC realized excellent frequency stability for fundamental (up to 60MHz) oscillation, and consists of an oscillation amplifier, 4-stage divider, 3-state output buffer and a built-in LDO. The operating voltage is from 1.62V to 3.63V, and the LDO holds down the characteristic change of the oscillation amplifier for operating voltage variation, and has been stabilized oscillation frequency. The 4-stage divider generates only one frequency selected of f0,f0/2,f0/4 f0/8 and f0/16 internal circuits is output. The 3-state output buffer is C-MOS compatible of high fan-out. The oscillation stopping current is very low stand-by mode below 1uA, therefore, it is suitable for the portable items of the communication equipment and the like. The pad arranges “L” location to be easy to put on 2016 size oscillator by wire bonding. !FEATURES "Frequency Stability ±1ppm@VDD±10% "Operating Voltage 1.62 to 3.63V "Maximum Oscillation Frequency Up to 60MHz "Low Operating Current 5mA typ.@60MHz/3.3V/15pF "4-Stage Divider Maximum Divider f0/16 "Built-in LDO "Oscillation Stop and Output Stand-by Function "3-State Output Buffer "Variable Pull-up Resistance on-Die "Oscillation Capacitors Cg and Cg on-Die "Package Outline Die/Wafer "C-MOS Technology !LINE-UP TABLE Type No. FOUT Internal Connect Short Open N A B B A 2 B A 4 B A 8 B A 16 Cg/Cd 9.3/10.7pF 9.3/10.7pF 9.3/10.7pF 9.3/10.7pF 9.3/10.7pF !PACKAGE OUTLINE NJU6214XC-X !PAD LOCATION Die VDD VSS FOUT XTI XTO CONT !COORDINATES No Pad Name X Y 1 CONT -189 231 2 XTI -189 77 3 XTO -189 -77 4 VSS -189 -231 5 FOUT 215 -231 6 VDD 222 231 Starting Point: Die Center Unit[um] Die Size: 0.64x0.60mm 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: VSS level A f0 B f0/2 f0/4 NJU6214 C D f0/8 *E f0/16 * Under Development !EXAMPLE OF PART NUMBER 1)NJU6214AW-L FOUT=f0, Wafer Thickness=140um 2)NJU6214CC-V FOUT= f0/4, Die Thickness=130um 2010/04/27 ( 1 / 7 ) NJU6214 Series !BLOCK DIAGRAM VDD Regulator VSS XTO Rf XTI Level Shifter Cg Cd A 1/N Divider B 3-State Buffer FOUT OSC Detector CONT !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 and f0/16 Note1) L Oscillation Stop and High impedance Output XTI Quartz Crystal Connecting Terminals XTO VSS VSS=0V : GND FOUT Frequency Output VDD VDD=1.62 to 3.63V Note1) Refer to the line-up table. !ABSOLUTE MAXIMUM RATINGS (VSS=0V, Ta=25°C) PARAMETER SYMBOL RATING UNIT Supply Voltage VDD -0.5 to +7.0 V Input Voltage VIN -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. 2010/04/27 ( 2 / 7 ) NJU6214 Series !ELECTRICAL CHARACTERISTICS PARAMETER Operating Voltage Output Frequency Stability SYMBOL VDD df/f CONDITIONS fosc=60MHz VDD±10% MIN 1.62 TYP ±1 MAX 3.63 (Ta=25°C) UNIT V ppm PARAMETER SYMBOL Operating Current IDD CONDITIONS A version, f0=60MHz, CL=15pF B version, f0/2=30MHz, CL=15pF C version, f0/4=15MHz, CL=15pF D version, f0/8=7.5MHz, CL=15pF *E version, f0/16=3.75MHz, CL=15pF CONT=VSS, No load MIN (VDD=1.8V,Ta=+25°C) TYP MAX UNIT 3.0 4.0 1.8 2.6 mA 1.3 2.0 1.0 2.0 0.9 2.0 1 uA V V V V uA uA 1.8 0.54 0.18 2.7 0.25 Oscillation Stopping Current Input Voltage Output Voltage Input Current ISTB VIH VIL VOH VOL IIN IOH=2mA IOL=2mA CONT=0.8VDD CONT=0.2VDD 1.26 0 1.62 1.9 0.1 3-state Off Leakage IOZ CONT=VSS, FOUT= VDD or VSS ±0.1 uA Current Feedback Resistance Rf 270 kΩ Internal Capacitor Cg fosc=60MHz 9.3 pF Internal Capacitor Cd fosc=60MHz 10.7 pF Oscillation Frequency fosc Recommendation Note4) 60 MHz Output Signal 45 50 55 % SYM CL=15pF, @VDD/2 Symmetry Output Signal Rise 3.2 5.0 ns tr CL=15pF, 0.1VDD to 0.9VDD Time Output Signal Fall 3.2 5.0 ns tf CL=15pF, 0.9VDD to 0.1VDD Time Output Disable time TPOZ CL=15pF, RL=1kΩ 100 ns Output Enable Time TPZO CL=15pF 1 ms Note4) The oscillation frequency range has used NJRC’s standard crystal for measurement.
