Overview
VISHAY TOIM4232 Vishay Semiconductors SIR Endec for IrDA Applications Integrated Interface Circuit ULC Technology: High performance gate array package using multiple metal layer CMOS technology featuring sub-micron channel lengths (0.
35 µm).
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 compatible 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.
The IrDA bit rate varies from 2.
4 kbit/s to 115.
2 kbit/s.
The TOIM4232 is using a crystal clock 3.
6864 MHz for its pulse stretching and shortening.
The clock can be generated by the internal oscillator.
An external clock can be used, too.
The TOIM4232 is programmable to operate from 1200 bit/s to 115.
2 kbit/s by the communication software through...
