3V to 5.5V, IrDA Infrared Transceiver with
Integrated RS-232 Interface
General Description
The MAX3130/MAX3131 combine an IrDA 1.2 compati-
ble 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 high-
gain/low-noise PIN-diode amplifier with 100µA of ambi-
ent 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) compresses/stretches sig-
nals to and from the external UART, allowing IrDA com-
munication even with non-IrDA UARTs.
A 2-driver/2-receiver RS-232 transceiver supports data
rates up to 120kbps. A proprietary, high-efficiency, dual
charge-pump power supply and a low-dropout trans-
mitter combine to deliver true RS-232 performance from
a single +3.0V to +5.5V supply. Selectable shutdown
for IR and RS-232 circuitry reduces supply current to
1µA.
The MAX3130 is optimized for applications using a sin-
gle UART for both infrared and RS-232 communication.
The infrared transmitter input and infrared receiver out-
put are multiplexed with one RS-232 transmitter input
and one RS-232 receiver output, respectively. The
MAX3131’s IrDA transceiver and RS-232 transceivers
are separate and have their own data inputs and outputs.
Both these devices require a minimum of external com-
ponents: four small 0.1µF capacitors, a photodiode, an
infrared LED, and a current-setting resistor.
