DESCRIPTION IRMS6100/IRMT6100 is an IrDA compliant 1.152 Mb/s infrared data transceiver. Its external Shut Down (SD) feature cuts current consumption to typically less than 0.01 A. The Shut Down (SD) mode disables the transmit input and tri-states the receiver output with a 500 k pull up. The transmit input is AC coupled, limiting transmit pulse duration to 70 s, preventing transmitter damage and continuous LED output which also provides protection for eye safety. Selectable LED transmit power (Pin 7) makes it easy for designers to use standard power mode (Pin 7=H) for 1 meter link or low power mode (Pin7=L) for 20 cm link.

Theory of Operation The IRMS6100/IRMT6100 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). at The ambient light suppressor can cancel up to 10 5.0 V. This will typically allow operation in all but direct sunlight. The receiver automatic gain control (AGC) circuit normalizes pulse width despite 120 dB signal range. The AGC also improves noise immunity while receiving a transmission by reducing gain so that noise less than 1/2 the peak signal height will not be detected. Asserting shutdown powers down the transceiver, and for bus multiplexing, tri-states the receiver output and disables TxD input. 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 1.4 V will turn on IR LED transmitter. This pin has a 500 k pulldown. 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. mW/cm2 Table 2.

The transmitter current limit is programmed to the high or low value by the state of Power Selection pin. If Power Select is low, low drive current limit is set. If the Power Select is high, high drive current limit is set.

Note 1: For Shut Down (SD) current to fall below 1.0 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: "AGC Attack Time" is the time required for internal AGC (Automatic Gain Control) attenuation to rise to within 10% of final value. Note 3: "AGC Settling" is the number of pulses within 100 s required for the output pulse width to settle to 90% of its final value. Note 4: "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 5: "AGC Decay Rate" is the rate at which the receiver gain increases following the cessation of signal input. Note 6: 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 1.0 V P-P of 120 Hz ripple. Note 7: RxD is suppressed (forced high) while (TxD) transmit pulse is active and for the indicated period following the end of the TxD pulse. Note 8: "First Pulse Width" specifies the width of the first pulse received after AGC has decayed to maximum sensitivity. "Subsequent Pulse Width" defines the width of subsequent pulses received within 100 s of first pulse.
