Theory of operation The IRMS6118/IRMT6118 Slimline--Infrared Data Transceiver consists of a detector photodiode, an IR LED transmitter, an IC containing ambient light suppressor, and Automatic Gain control circuitry (AGC). The ambient light suppressor can cancel up to 10 mW/cm2 (typical) at 5.0 V of DC ambient signal. This will typically allow operation in all but direct sunlight. The AGC in the IC is to keep the system output constant by varying the gain to accommodate a wide range of input signals. It also provides noise immunity in the high noise ambient environment. For normal operation of the transmit and receiver modes, the Shut Down (SD) pin should be held low. It is recommended that this pin be connected to GND if Shut Down (SD) mode is not used. In receive mode, the receiver output (RxD) which normally stays high, will go low for duration of the receive 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 transmit mode, by asserting the TxD pin above 12 VCC will turn on IR LED transmitter. At the LED Anode (pin 1) connect this pin to VCC or unregulated power supply (not to exceed VCC + 4.0 V), through a resistor to set the proper LED current to reduce the thermal dissipation and to lower LED current.

Note 1: For Shut Down (SD) current to fall below 1 A requires driving Shut Down (SD) to within 0.5 V of VCC to ensure cutoff 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: "Near-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. "Transmit Receiver Latency" is commonly called "Receiver Latency" or "Transmitter Turnaround Time." Note 3: "AGC Decay Rate" is the rate at which the receiver gain increases following the cessation of signal input.
Note 4: The receiver VCC power supply rejection is significantly better for small ripple of less than 100 mVP-P than for larger values. For ripple of more than 100 mVP-P , internal circuits can maintain operating headroom provided that the slew rate is significantly slower. Typically, these specifications allow operation without an external filter from either switching supplies with less than 50 mV P-P ripple or unregulated supplies with less than 1 VP-P of 120 Hz ripple. Note 5: If the low going RxD pulse width exceeds 100 s, then the maximum DC ambient irradiance has been exceeded. Note 6: RxD is suppressed (forced high) while (TxD) transmit pulse is active and for the indicated period following the end of the TxD pulse.
