20 rev. 1.6 si8640/41/42/45 2. functional description 2.1. theory of operation the operation of an si864x channel is analogous to that of an opto coupler, except an rf carrier is modulated instead of light. this simple archit ecture provides a robust isolated data path and requires no special considerations or initialization at start-up. a simplified block diagram for a single si864x channel is shown in figure 6. figure 6. simplified channel diagram a channel consists of an rf transmitter and rf receiver separated by a semiconductor-based isolation barrier. referring to the transmitter, input a modulates the carrier provided by an rf oscillator using on/off keying. the receiver contains a demodulator that decodes the input state according to its rf energy content and applies the result to output b via the output driv er. this rf on/off keying scheme is superior to pulse code schemes as it provides best-in-class noise immunity, low power consum ption, and better immunity to magnetic fields. see figure 7 for more details. figure 7. modulation scheme rf oscillator modulator demodulator a b semiconductor- based isolation barrier transmitter receiver input signal output signal modulation signal free datasheet http://www..net/

rev. 1.6 25 si8640/41/42/45 3.3. layout recommendations to ensure safety in the end us er application, high voltage circ uits (i.e., circuits with >30 v ac ) must be physically separated from the safety extra-low voltage circuits (selv is a circuit with <30 v ac ) by a certain distance (creepage/clearance). if a component, su ch as a digital isolator, straddles this isolation barrier, it must meet those creepage/clearance requirements and also provide a sufficiently large high-voltage breakdown protection rating (commonly referred to as working voltage protection). table 5 on page 15 and table 6 on page 16 detail the working voltage and creepage/clearan ce capabilities of the si86xx. thes e tables also detail the component standards (ul1577, iec60747, csa 5a), which are readily accepted by certif ication bodies to provide proof for end-system specifications requirements. refer to t he end-system specification (6 1010-1, 60950-1, 60601-1, etc.) requirements before starting any design that uses a digital isolator. 3.3.1. supply bypass the si864x family requires a 0.1 f bypass capacitor between v dd1 and gnd1 and v dd2 and gnd2. the capacitor should be placed as close as possible to the package. to enhance the robustness of a design, the user may also include resistors (50?300 ? ) in series with the inputs and outp uts if the system is excessively noisy. 3.3.2. output pin termination the nominal output impedance of an isolat or driver channel is approximately 50 ? , 40%, which is a combination of the value of the on-chip series term ination resistor and channel resistance of the output driver fet. when driving loads where transmission line effects will be a factor, output pins should be appr opriately terminated with controlled impedance pcb traces. 3.4. fail-saf e operating mode si86xx devices feature a selectable (by ordering option ) mode whereby the default ou tput state (when the input supply is unpowered) can either be a logic high or logi c low when the output supply is powered. see table 12 on page 22 and "5. ordering guide" on page 28 for more information. free datasheet http://www..net/
