Description
The TOIM3232 IC provides proper pulse shaping for the front end infrared transceivers of the 4000-series (4000-series devices are infrared transceiver compliant to the IrDA standard made by Vishay Telefunken), as specified by the IrDA standard. In the transmit mode, the TOIM3232 shortens the RS232 output signal to IrDA compatible electrical pulses to drive the infrared. In the receive mode, the TOIM3232 stretches the received infrared pulses to the proper bit width at the operating bit rate. The IrDA bit rate varies between 2.4 kbit/s to 115.2 kbit/s.
