document number: 82589 www.vishay.com revision 05-july-02 2 figure 1. block diagram theory of operation the IRM5000D microline infrared data transceiver consists of a detector photodiode, an ir led transmitter, an ic con- taining ambient light suppressor and automatic gain control circuitry (agc). the agc in the ic is to keep the system output constant by varying the gain to accommodate a wide range of input sig- nals. it also provides noise immunity in the high noise ambi- ent environment. for normal operation of the transmit and receiver modes, the shut down (sd) pin should be held low. it is recom- mended that this pin be connected to gnd if shut down (sd) feature is not used. in receive mode, the receiver output (rxd) which normally stays high, will go low for duration of the received pulses. it is a push-pull cmos driver capable of driving a standard cmos or ttl load. no external pull-up or pull-down resistor is required. in transit mode, by asserting the txd pin above 1 2 v cc will turn on ir led transmitter. led anode (pin 1) can be con- nected to v cc or an unregulated power supply (not to exceed v cc + 4.0 v). it is recommended that a series resis- tor be connected at pin1 (led anode) to reduce the thermal dissipation and to lower led current when v led is greater than 3.3 v. + - + - receiver output receive detector regulated voltage & current sources power down current limited transmit error amp v cc detector reference lowpass filter ir led agc & signal reference processor agc tx blanking switched current source tx in tx input buffer main amp pre amp ambient dc cancelling led anode receive ouput blanking txd sd rxd tri-state control tri-state cmos buffer driver gnd 500 k ? differential photodiode 500 k ? v cc v cc v cc pin 2 pin 6 pin 5 pin 3 pin 4 pin 1 table 2. microline IRM5000D truth table inputs outputs sd v cc txd detector rxd led high 2.4 to 5.0 v x=don? care state x=don? care state 500 k ? pull-up off low 2.4 to 5.0 v high high on 2.4 to 5.0 v low <0.4 w/cm 2 high off 2.4 to 5.0 v <4.0 w/cm 2 low

document number: 82589 www.vishay.com revision 05-july-02 4 table 6. transmitter output note 1: for shut down (sd) current to fall below 1.0 a requires driving shut down (sd) to within 0.5 v of v cc to ensure cut- off of the pmos transistor of the input cmos totem pole. in most applications this is not an issue if shut down (sd) is driven from a cmos driver supplied from the same voltage supply. note 2: ?ear-far receiver latency?is the time required for the agc and ambient correction circuits to return to maximum sensitivity (far) following reception of a maximum (near) signal or a change in ambient. ?ransmit receiver latency? is commonly called ?eceiver latency?or ?ransmitter turn- around time? note 3: the receiver v cc power supply rejection is signi?antly bet- ter for small ripple of less than 100 mv p-p than for larger val- ues. for ripple of more than 100 mv p-p , internal circuits can maintain operating headroom provided that the slew rate is signi?antly slower. typically, these speci?ations allow operation without an external ?ter from either switching sup- plies with less than 50 mv p-p ripple or unregulated supplies with less than 1.0 v p-p of 120 hz ripple. parameter sym. min. typ. max. unit conditions maximum data rate 115.2 kb/s txd pulse width=1.63 s txd radiant intensity 40 70 230 mw/sr 5.1 ? led resistor, 5.0 v led supply txd 1/2 angle 15 20 30 degrees irda physical layer specification 1.3 txd peak wavelength 850 870 900 nm radiant 50% pulse width, tx high/low 1.51 1.61 1.71 s txd=1.63 s, i led =330 ma, v cc =5.0 v optical rise/fall time, tx high or low 30 600 ns txd=1.63 s, v cc =5.0 v i led limit, tx standard 250 350 400 ma txd=v cc , led anode=3.3 v, v cc =5.0 v figure 2. timing diagrams 100 s 1.6 s 8.7 s 8.7 s latency 5.0 v 0 v sd 5.0 v 0 v txd in 5.0 v 0 v rxd out receive mode transmit mode 5.0 v 0 v sd optical signal received txd in rxd out 5.0 v 0 v 5.0 v 0 v 5.0 v 0 v sd 5.0 v 0 v txd in 5.0 v 0 v rxd out led optical signaloutput e e 1.6 s (echo-off)
