2010/04/27 ( 1 / 7 ) NJU6214 series small-sized 1.8v operating voltage fundamental quartz crystal oscillator ic ! general description ! package outline the NJU6214 series is a c-mos quartz crystal oscillator ic realized excellent frequency st ability 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 char acteristic change of the oscillation amplifier for operating voltage variation, and has been stabilized oscilla tion frequency. the 4-stage divider generates only one frequency selected of f 0 ,f 0 /2,f 0 /4 f 0 /8 and f 0 /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 suit able 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 ! pad location " frequency stability 1ppm@v dd 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 f 0 /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 ! coordinates ! example of part number 1)NJU6214aw-l f out =f 0 , wafer thickness=140um 2)NJU6214cc-v f out = f 0 /4, die thickness=130um no pad name x y 1 cont -189 231 2 xti -189 77 3 xto -189 -77 4v ss -189 -231 5f out 215 -231 6v dd 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: v ss level internal connect type no. f out short open n cg/cd a f 0 a b - 9.3/10.7pf b f 0 /2 b a 2 9.3/10.7pf c f 0 /4 b a 4 9.3/10.7pf d f 0 /8 b a 8 9.3/10.7pf NJU6214 *e f 0 /16 b a 16 9.3/10.7pf * under development NJU6214xc-x die cont xti v ss f out xto v dd
