2009/03/19 ( 1 / 6 ) NJU6312 series 0.9v operation fundamental quartz crystal oscillator ic for flip ! general description ! pakage outline the NJU6312 series is c-mos quartz crystal oscillator ic for fundamental (up to 80mhz) oscillation. the pad arrangement suitable for flip die mount simplifies development of small-sized oscillator. the operating voltage is from 0.9v to 3.0v, and the pad layout is for flip die based on smaller 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 3.0v " 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-chip " pad layout for flip die " package outline thin-die " c-mos technology ! line-up table ! coordinates starting point: die center unit[um] ! example of part number die size: 0.8x0.6mm 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 NJU6312 f f 0 /32 connected f line 8/9pf no pad name x y 1 xt -271 171 2v dd -271 -17 3f out -271 -171 4v ss 271 -171 5 cont 271 17 6 xt 271 171 NJU6312xc-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
