3V to 5.5V, IrDA Infrared Transceiver with Integrated RS-232 Interface
General Description
The MAX3130/MAX3131 bine an IrDA 1.2 patible infrared transceiver with an RS-232 interface- all in a single 3V-powered hybrid microcircuit. The infrared transceiver supports IrDA data rates of 2.4kbps to 115kbps. The infrared receive channel provides a highgain/low-noise PIN-diode amplifier with 100µA of ambient photodiode current rejection at a +3V supply. A high-power LED driver capable of sinking 200mA is included in the infrared transmit path. The on-board encoder/decoder (ENDEC) presses/stretches signals to and from the external UART, allowing IrDA munication...
