TOIM4232 Description
The TOIM4232 Endec IC provides proper pulse shaping for the SIR IrDA® front end infrared transceivers as of the 4000-series. For transmitting the TOIM4232 shortens the RS232 output signal to IrDA patible electrical pulses to drive the infrared transmitter. In the receive mode, the TOIM4232 stretches the received infrared pulses to the proper bit width depending on the operating bit rate.
