2002/03/11 ( 1 / 4 ) NJU6396 3rd. over tone quartz crystal oscillator for 166mhz general description the NJU6396 is a c-mos ic for xos, and can oscillate up to 166mhz maximum at very low operating voltage. high fan-out is gained from low operating voltage with 3-state output buffer and the oscillation amplifier that is realized very low stand-by current using nand circuit. furthermore, not using pll, the electrical character shows a very low jitter. the NJU6396 is suitable for mobile, optical communications (included wdm system) and not to mention previous applications; computer & peripherals, telecommunications, lan/wan, wireless and so on. features operating voltage 2.7 to 3.6v maximum oscillation frequency 166mhz high fan-out i oh /i ol = 8ma v dd =3.3v oscillation stop and output stand-by function 3-state output buffer oscillation capacitors cg and cg on-chip package outline thin-chip c-mos technology starting point:chip center unit[um] chip size:0.7x0.75mm thin-chip thickness:200 20um pad size:90x90um ! block diagram no pad name x y 1 cont -178 231 2 xt -178 77 3 xt -178 -77 4 v ss -178 -231 5 f out 206 -231 8 v dd 206 231 product s p ecification thin-chip cont xt v ss f out xt v dd NJU6396c-d package outline pad location ! coordinates cont xt xt cg cd rf buffer state 3 ? out f dd v ss v
