adum2210/adum2211 data sheet rev. a | page 16 of 2 applications information pcb layout the adum221x 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 is 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 09233-012 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% 09233-013 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 adum221x component. propagation delay skew refers to the maximum amount the propagation delay differs among multiple adum221x 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 adum221x magnetic field immunity is set by the condition in which induced voltage in the transformer 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 adum221x 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 adum221x 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 09233-014 figure 14. maximum allowable external magnetic flux density
