il715/il716/il717 7 80 ns application information electrostatic disch arge sensitivity this product has been tested for electrostatic sensitivity to the limits stated in the specifications. however, nve recommends that all integrated circuits be handled with appropriate care to avoid damage. damage caused by inappr opriate handling or storage could range from performance degrad ation to complete failure. electromagnetic compatibility isoloop isolators have the lowest emc footprint of any isolation technology. isoloop isolators? wheatstone bridge configuration and differential magnetic field signaling ensure excellent emc performance against all relevant standards. these isolators are fully compliant with generic emc standards en50081, en50082-1 and the umbrella line-voltage standard for information technology equipment (ite) en61000. nve has completed compliance tests in the categories below: en50081-1 residential, commercia l & light industrial methods en55022, en55014 en50082-2: industrial environment methods en61000-4-2 (esd), en61000-4-3 (electromagnetic field immunity), en61000-4-4 (ele ctrical transien t immunity), en61000-4-6 (rfi immunity), en61000-4-8 (power frequency magnetic field immunity), en61000-4-9 (pulsed magnetic field), en61000-4-10 (damped oscillatory magnetic field) env50204 radiated field from digita l telephones (immunity test) immunity to external magnetic fields is even higher if the field direction is ?end-to-end? rather than to ?pin-to-pin? as shown in the diagram below: cross-axis field direction dynamic power consumption isoloop isolators achieve their low power consumption from the way they transmit data across the isolation barrier. by detecting the edge transitions of the input logic signal and converting these to narrow current pulses, a magnetic field is created around the gmr wheatstone bridge. depending on the direction of the magnetic field, the bridge causes the output comparator to switch following the input logic signal. since the current pulses are narrow, about 2.5 ns, the power consumption is independent of mark-to-space ratio and solely dependent on frequency. this has obvious advantages over optocouplers, which have power consumption heavily dependent on mark-to-space ratio. power supply decoupling both power supplies to these devi ces should be decoupled with low esr 47 nf ceramic capacitors. ground planes for both gnd 1 and gnd 2 are highly recommended for data rates above 10 mbps. capacitors must be located as close as possible to the v dd pins. signal status on start-up and shut down to minimize power dissipation, i nput signals are differentiated and then latched on the output side of the isolation barrier to reconstruct the signal. this could result in an ambiguous output state depending on power up, shutdown and power loss sequencing. therefore, the designer should cons ider including an initialization signal in the start-up circuit. ini tialization consists of toggling the input either high then low, or low then high. data transmission rates the reliability of a transmission system is directly related to the accuracy and quality of the transmitted digital information. for a digital system, those parameters which determine the limits of the data transmission are pulse widt h distortion and propagation delay skew. propagation delay is the time taken for the signal to travel through the device. this is usually different when sending a low-to-high than when sending a high-to-low signal. this difference, or error, is called pulse width distortion (pwd) and is usually in nanoseconds. it may also be expressed as a percentage: pwd% = maximum pulse width distortion (ns) x 100% signal pulse width (ns) for example, with data rates of 12.5 mbps: pwd% = 3 ns x 100% = 3.75% this figure is almost three times better than any available optocoupler with the same temperature range, and two times better than any optocoupler regardless of published temperature range. isoloop isolators exceed the 10% maximum pwd recommended by profibus, and will run to nearly 35 mb within the 10% limit. propagation delay skew is the signal propagation difference between two or more channels. this becomes significant in clocked systems because it is undesirable for the clock pulse to arrive before the data has settled. short propagation delay skew is therefore especially critical in high data rate parallel systems for establishing and maintaining accuracy and repeatability. worst- case channel-to-channel skew in an il700 isolator is only 3 ns, which is ten times better than any optocoupler. il700 isolators have a maximum propagation delay skew of 6 ns, which is five times better than any optocoupler.
