high performance products 1 www.semtech.com revision 5/january 14, 2002 sk10/100el16v differential receiver with variable output swing description features functional block diagram the sk10/100el16v is a differential receiver with variable output swing. its vctrl input controls the amplitude of the q and q* outputs. the operating range of the el16v control input, vctrl, is from vbb (large swing) to vcc (min swing), see figure 2. simple control of the output swing can be obtained by a variable resistor between the vbb and vcc pins, with wiper driving ctrl. typical application circuits and results are described in figures 1a, 1b, and 2. the sk10/100el16v provides a vbb output for either single-ended use or as a dc bias for ac coupling to the device. the vbb pin should be used only as a bias for the el16v as its current sink/source capability is limited. whenever used, the vbb pin should be bypassed to vcc via a 0.01 f capacitor. under open input conditions, the pulldown resistor on d, pulldown and pullup resistors on d* will force the q output low and q* output high. the vctrl pin should be bypassed to vcc via a 0.01 f capacitor when the pin is used. ? extended supply voltage range: (vee = ?5.5v to ?3.0v, vcc = 0v) or (vcc = +3.0v to +5.5v, vee = 0v) high bandwidth output transitions 240 ps typical propagation delay vbb output internal input resistors: pulldown on d, pulldown and pullup on d* q output will default low with inputs open or at vee new differential input common mode range esd protection of >4000v specified over industrial temperature range: ?40 o c to 85 o c available in both 8 pin soic (150 mil) and msop (3mm x 3mm) packages flammability rate: ul-94 code v-0. moisture sensitivity: level 1. pin description n i pn o i t c n u f * d , ds t u p n i a t a d l a i t n e r e f f i d * q , qs t u p t u o a t a d l a i t n e r e f f i d b b ve g a t l o v t u p t u o e c n e r e f e r l r t c vl o r t n o c g n i w s t u p t u o high performance products 1 2 3 4 8 7 6 5 75k 75k 36.5k v ctrl v bb d d* v cc v ee q q*
