10 propagation delay, pulse-width distortion and propaga - tion delay skew propagation delay is a fgure of merit which describes how quickly a logic signal propagates through a system. the propagation delay from low to high (t plh ) is the amount of time required for an input signal to propagate to the output, causing the output to change from low to high. similarly, the propagation delay from high to low (t phl ) is the amount of time required for the input signal to propa - gate to the output, causing the output to change from high to low (see figure 9). pulse-width distortion (pwd) results when t plh and t phl difer in value. pwd is defned as the diference between t plh and t phl and often pwd is defned as the diference between t plh and t phl and often determines the maxi - mum data rate capability of a transmission system. pwd can be expressed in percent by dividing the pwd (in ns) by the minimum pulse width (in ns) being transmitted. typically, pwd on the order of 20-30% of the minimum pulse width is tolerable; the exact fgure depends on the particular application (rs232, rs422, t-1, etc.). propagation delay skew, t psk , is an important parameter to consider in parallel data applications where synchroni - zation of signals on parallel data lines is a concern. if the parallel data is being sent through a group of opto - couplers, diferences in propagation delays will cause the data to arrive at the outputs of the optocouplers at difer - ent times. if this diference in propagation delays is large enough, it will determine the maximum rate at which par - allel data can be sent through the optocouplers. propagation delay skew is defned as the diference be - tween the minimum and maximum propagation delays, either t plh or t phl , for any given group of optocouplers which are operating under the same conditions (i.e., the same supply voltage, output load, and operating temper - ature). as illustrated in figure 10, if the inputs of a group of optocouplers are switched either on or off at the same time, t psk is the diference between the shortest propaga - tion delay, either t plh or t phl , and the longest propagation delay, either t plh or t phl . as mentioned earlier, t psk can de - termine the maximum parallel data transmission rate. figure 10 is the timing diagram of a typical parallel data application with both the clock and the data lines being sent through optocouplers. the fgure shows data and clock signals at the inputs and outputs of the optocou - plers. to obtain the maximum data transmission rate, both edges of the clock signal are being used to clock the data; if only one edge were used, the clock signal would need to be twice as fast. propagation delay skew represents the uncertainty of where an edge might be after being sent through an opt - ocoupler. figure 10 shows that there will be uncertainty in both the data and the clock lines. it is important that these two areas of uncertainty not overlap, otherwise the clock signal might arrive before all of the data outputs have settled, or some of the data outputs may start to change before the clock signal has arrived. from these considerations, the absolute minimum pulse width that can be sent through optocouplers in a parallel application is twice t psk . a cautious design should use a slightly longer pulse width to ensure that any additional unc er tain t y in the r est of the cir cuit does not cause a problem. data input s cl ock d a t a output s clock t psk t psk 50% 50% t psk i f v o i f v o 50%, cmos 50%, cmos figure 9. propagation delay and skew waveform figure 10. parallel data transmission example
11 the t psk specifed optocouplers ofer the advantages of guaranteed specifcations for propagation delays, pulse- width distortion and propagation delay skew over the rec - ommended temperature, and power supply ranges. powering sequence v dd needs to achieve a minimum level of 3.0v before powering up the output connecting component. input limiting resistors ACPL-071L and acpl-074l are direct current driven (figure 8), and thus elimina t e the need f or input po w er supply . t o limit the amount of current fowing through the led, it is recommended that a 210ohm resistor is connected in se - ries with anode of led (i.e. pin 2 for ACPL-071L and pin 1 and 4 f or a cpl -074l) a t 5v input sig nal . a t 3.3v input sig - nal, it is recommended to connect 80ohm resistor in series with anode of led. the recommended limiting resistors are based on the assumption that the driver output impedence is 50? (as shown in figure 11). speed improvement a peaking capacitor can be placed across the input cur - rent limit resistor (figure 11) to achieve enhanced speed performance. the value of the peaking cap is dependent to the rise and fall time of the input signal and supply volt - ages and led input driving current (i f ). f igur e 12 sho w s sig nifcan t impr o v emen t of pr opaga tion dela y and pulse with distortion with added peak capacitor at driving cur - rent of 14ma and 3.3v or 5v power supply. figure 11 connection of peaking capacitor (cpeak) in parallel of the input limiting resistor (rllimit) to improve speed performance figure 12. improvement of t p and pwd with added 100pf peaking capacitor in parallel of input limiting resistor. t a - temperature - o c t p - propagation delay; pwd-pulse width distortion -ns t a - temperature - o c t p - propagation delay; pwd-pulse width distortion -ns 0 . 0 0 5 . 0 0 1 0 . 0 0 1 5 . 0 0 2 0 . 0 0 2 5 . 0 0 3 0 . 0 0 3 5 . 0 0 - 4 0 - 2 0 0 2 0 4 0 6 0 8 0 1 0 0 t phl t plh t plh t phl |pwd| with peaking cap without peaking cap 0.00 5.00 10.00 15.00 20.00 25.00 30.00 -40 -20 0 20 40 60 80 100 t phl t plh t plh t phl |pwd| with peaking cap without peaking cap (i) v dd =3.3v, c peak =100pf, r limit =80 (ii) v dd =5v, c peak =100pf, r limit =210 g n d 2 v d d 2 0 . 1 f g n d 1 r l i m i t s h i e ld v in + - c pe a k v o r d r v =5 0 ?
