U2532B
IR Transmitter and Receiver
Description
The IC U2532B is a complete IR-Transmitter-Receiver IC according to the new IrDA 1.
0 standard.
ASK-modulation is also possible.
Only an external PIN-photodiode and an infrared emitting diode with current limiting resistor must be connected to the corresponding pins.
The amplifier with Schmitt-Trigger formed output signal and the IR-driver need no further external components.
The IC allows data rates from 2.
4 kbit/s to 115.
2 kbit/s and up to 500 kHz for ASK-modulation.
Two different sensitivity modes, which can be programmed by applying a “High” or “Low”
voltage at pin SC, ensure either an increase in transmission distance or...
