• Manufacturer Part Number: IRM7001
• Description: Sir Modulator/demodulator
• Manufacturer: Vishay

IRM7001 SIR Modulator/Demodulator functions extremely well
with Infineon IRMS6118/IRMT6118 and IRM5000 SIR (115 Kb/
s) Infrared Data transceivers. These products provide the user
with a low component count and cost effective way of imple-
menting an IrDA port on their products where the microcontrol-
ler does not have a built-in IrDA port support

Figures 12, 13, and 14 show the schematic, PCB front side and
back side for an IRM5000/7001 based port. Table 7 provides
the Bill of Materials list to implement the port. Figures 15, 16,
and 17 show the schematic, PCB front and the back side for an
IRMS6118/IRM7001 based port. Table 8 provides the Bill of
Materials list to implement the port.
