TOIM4232 Datasheet (Vishay Siliconix) - SIR Endec for IrDA Applications Integrated Interface Circuit

TOIM4232, SIR Endec for IrDA Applications Integrated Interface Circuit

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 compatible electrical pulses to drive the infrared transmitter.

In the receive mode, the TOIM4232 stretc
