ADUM2200/adum2201 rev. 0 | page 16 of 20 applications information pc board layout the adum220x digital isolator requires no external interface circuitry for the logic interfaces. power supply bypassing is strongly recommended at the input and output supply pins (see figure 12 ). bypass capacitors are most conveniently connected between pin 1 and pin 3 for v dd1 and between pin 14 and pin 16 for v dd2 . the capacitor value should be between 0.01 f and 0.1 f. the total lead length between both ends of the capacitor and the input power supply pin should not exceed 20 mm. bypassing between pin 3 and pin 7 and between pin 9 and pin 14 should be considered unless the ground pair on each package side are connected close to the package. gnd 1 nc v dd1 v ia /v oa gnd 2 nc v dd2 v oa /v ia v ib v ob nc nc gnd 1 nc nc gnd 2 07235-012 figure 12. recommended printed circuit board layout in applications involving high common-mode transients, care should be taken to ensure that board coupling across the isolation barrier is minimized. furthermore, the board layout should be designed such that any coupling that does occur equally affects all pins on a given component side. failure to ensure this could cause voltage differentials between pins exceeding the devices absolute maximum ratings , thereby leading to latch-up or permanent damage. propagation delay-related parameters propagation delay is a parameter that describes the length of time it takes for a logic signal to propagate through a compo- nent. the propagation delay to a logic low output can differ from the propagation delay to logic high. input ( v ix ) output (v ox ) t plh t phl 50% 50% 07235-018 figure 13. propagation delay parameters pulse width distortion is the maximum difference between these two propagation delay values and is an indication of how accurately the input signals timing is preserved. channel-to-channel matching refers to the maximum amount the propagation delay differs among channels within a single adum220x component. propagation delay skew refers to the maximum amount the propagation delay differs among multiple adum220x components operated under the same conditions. dc correctness and magnetic field immunity positive and negative logic transitions at the isolator input cause narrow (~1 ns) pulses to be sent via the transformer to the decoder. the decoder is bistable and is therefore either set or reset by the pulses, indicating input logic transitions. in the absence of logic transitions at the input for more than ~1 s, a periodic set of refresh pulses indicative of the correct input state is sent to ensure dc correctness at the output. if the decoder receives no internal pulses for more than approximately 5 s, the input side is assumed to be without power or nonfunctional; in which case, the isolator output is forced to a default state (see table 11 and table 12 ) by the watchdog timer circuit. the limitation on the adum220x magnetic field immunity is set by the condition in which induced voltage in the trans- former receiving coil is large enough to either falsely set or reset the decoder. the following analysis defines the conditions under which this can occur. the 3 v operating condition of the adum220x is examined because it represents the most suscept- ible mode of operation. the pulses at the transformer output have an amplitude greater than 1.0 v. the decoder has a sensing threshold at about 0.5 v, therefore establishing a 0.5 v margin in which induced voltages can be tolerated. the voltage induced across the receiving coil is given by v = (? d / dt ) r n 2 ; n = 1, 2,, n where: is the magnetic flux density (gauss). n is the number of turns in the receiving coil. r n is the radius of the n th turn in the receiving coil (cm). given the geometry of the receiving coil in the adum220x and an imposed requirement that the induced voltage be at most 50% of the 0.5 v margin at the decoder, a maximum allowable magnetic field is calculated as shown in figure 14 . magnetic field frequency (hz) 100 maximum allowable magnetic flux density (kgauss) 0.001 1m 10 0.01 1k 10k 10m 0.1 1 100m 100k 07235-019 figure 14. maximum allowable external magnetic flux density
ADUM2200/adum2201 rev. 0 | page 17 of 20 for example, at a magnetic field frequency of 1 mhz, the maximum allowable magnetic field of 0.2 kgauss induces a voltage of 0.25 v at the receiving coil. this is about 50% of the sensing threshold and does not cause a faulty output transition. similarly, if such an event were to occur during a transmitted pulse (and was of the worst-case polarity), it would reduce the received pulse from >1.0 v to 0.75 vstill well above the 0.5 v sensing threshold of the decoder. the preceding magnetic flux density values correspond to specific current magnitudes at given distances away from the adum220x transformers. figure 15 expresses these allowable current magnitudes as a function of frequency for selected distances. as can be seen, the adum220x is immune and can be affected only by extremely large currents operated at high frequency and very close to the component. for the 1 mhz example noted previously, one would have to place a 0.5 ka current 5 mm away from the adum220x to affect operation of the component. magnetic field frequency (hz) maximum allowable current (ka) 1000 100 10 1 0.1 0.01 1k 10k 100m 100k 1m 10m distance = 5mm distance = 1m distance = 100mm 07235-020 figure 15. maximum allowable current for various current-to-adum220x spacings note that at combinations of strong magnetic field and high frequency, any loops formed by printed circuit board traces can induce sufficiently large error voltages to trigger the thresholds of succeeding circuitry. care should be taken in the layout of such traces to avoid this possibility. power consumption the supply current at a given channel of the adum220x isolator is a function of the supply voltage, the channels data rate, and the channels output load. for each input channel, the supply current is given by i ddi = i ddi (q) f 0.5 f r i ddi = i ddi (d) (2 f ? f r ) + i ddi (q) f > 0.5 f r for each output channel, the supply current is given by i ddo = i ddo (q) f 0.5 f r i ddo = ( i ddo (d) + (0.5 10 ?3 ) c l v ddo ) (2 f ? f r ) + i ddo (q) f > 0.5 f r where: i ddi (d) , i ddo (d) are the input and output dynamic supply currents per channel (ma/mbps). c l is the output load capacitance (pf). v ddo is the output supply voltage (v). f is the input logic signal frequency (mhz, half of the input data rate, nrz signaling). f r is the input stage refresh rate (mbps). i ddi (q) , i ddo (q) are the specified input and output quiescent supply currents (ma). to calculate the total i dd1 and i dd2 , the supply currents for each input and output channel corresponding to i dd1 and i dd2 are calculated and totaled. figure 6 and figure 7 provide per- channel supply currents as a function of data rate for an unloaded output condition. figure 8 provides per-channel supply current as a function of data rate for a 15 pf output condition. figure 9 through figure 11 provide total i dd1 and i dd2 as a function of data rate for ADUM2200/adum2201 channel configurations.
ADUM2200/adum2201 rev. 0 | page 18 of 20 insulation lifetime all insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. the rate of insulation degradation is dependent on the characteristics of the voltage waveform applied across the insulation. in addition to the testing performed by the regulatory agencies, analog devices carries out an extensive set of evaluations to determine the lifetime of the insulation structure within the adum220x. analog devices performs accelerated life testing using voltage levels higher than the rated continuous working voltage. accel- eration factors for several operating conditions are determined. these factors allow calculation of the time to failure at the actual working voltage. the values shown in table 10 summarize the peak voltage for 50 years of service life for a bipolar ac operating condition and the maximum csa/vde approved working voltages. in many cases, the approved working voltage is higher than 50-year service life voltage. operation at these high working voltages can lead to shortened insulation life in some cases. the insulation lifetime of the adum220x depends on the voltage waveform type imposed across the isolation barrier. the i coupler insulation structure degrades at different rates, depending on whether the waveform is bipolar ac, unipolar ac, or dc. figure 16 , figure 17 , and figure 18 illustrate these different isolation voltage waveforms. bipolar ac voltage is the most stringent environment. the goal of a 50-year operating lifetime under the ac bipolar condition determines the analog devices recommended maximum working voltage. in the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower. this allows operation at higher working voltages while still achieving a 50 year service life. the working voltages listed in table 10 can be applied while main- taining the 50-year minimum lifetime, provided the voltage conforms to either the unipolar ac or dc voltage cases. any cross insulation voltage waveform that does not conform to figure 17 or figure 18 should be treated as a bipolar ac waveform and its peak voltage should be limited to the 50-year lifetime voltage value listed in table 10 . note that the voltage presented in figure 17 is shown as sinusoidal for illustration purposes only. it is meant to represent any voltage waveform varying between 0 v and some limiting value. the limiting value can be positive or negative, but the voltage cannot cross 0 v. 0v rated peak voltage 07235-021 figure 16. bipolar ac waveform 0v rated peak voltage 07235-022 figure 17. unipolar ac waveform 0v rated peak voltage 07235-023 figure 18. dc waveform
