DESCRIPTION
The IRM7001 SIR-Encoder/Decoder is a CMOS modulator/
demodulator chip that is used to both encode and decode
information as per the IrDA® SIR (Serial InfraRed) signal mod-
ulation and demodulation scheme. This chip is designed to
work with Infineon IrDA compatible transceivers and all other
IrDA compatible transceivers. The chip contains a clock
divider circuit used to generate the 16X clock internally. This
makes it very suitable for microcontroller-based embedded
system design.
