2009/03/19 ( 1 / 6 ) NJU6316 series 0.9v operation fundamental quartz crystal oscillator ic ! general description ! pakage outline the NJU6316 series is c-mos quartz crystal oscillator ic for fundamental (up to 80mhz) 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 f 0 ,f 0 /2,f 0 /4 f 0 /8, f 0 /16 and f 0 /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. ! features ! pad location " operating voltage 0.9 to 3.3v " maximum oscillation frequency 80mhz " low operating current " 5-stage divider maximum divider f 0 /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 ! line-up table ! coordinates starting point: die center unit[um] ! example of part number die size: 0.7x0.75mm 1)nju6312aw-l die thickness (c-l): 140 10um f out =f 0 , wafer thickness=140um wafer thickness (w-l): 140 10um 2)nju6312cc-l pad size: 90x90um f out = f 0 /4, die thickness=140um die substrate: v dd level ! block diagram type no. f out internal connect cg/cd a f 0 connected a line 8/9pf b f 0 /2 connected b line 8/9pf c f 0 /4 connected c line 8/9pf d f 0 /8 connected d line 8/9pf e f 0 /16 connected e line 8/9pf NJU6316 f f 0 /32 connected f line 8/9pf no pad name x y 1 cont -178 231 2 xt -178 77 3 xt -178 -77 4v ss -178 -231 5f out 206 -231 6v dd 206 231 NJU6316xc-l thin-die cont xt v ss f out xt v dd xt xt co nt c g cd rf 1/2 a bc d 1/2 1/2 3-state buffer f out 1/2 e 1/2 f v dd v ss
