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. !PACKAGE OUTLINE !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 !PAD LOCATION !LINE-UP TABLE !COORDINATES Type No. NJU6314 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 NJU6314XC-X Die VDD VSS FOUT XT XT CONT Cg/Cd 8/9pF 8/9pF 8/9pF 8/9pF 8/9pF 8/9pF 8/9pF No 1 2 3 4 5 6 Note) Please contact us about the divider type (B to G) of 130um die and wafer.
