Description
Responding to the volumetric constraints of today’s
ultra-compact and power conscious portable prod-
ucts, Infineon has developed the next generation in
infrared wireless communication transceivers. The
transceiver has been designed to support up to 4
Mbit/s IrDA, HP-SIR, Local Talk and Sharp
ASK modes. The device combines an LED, photo-
diode, LED driver and a fully differential receiver into a
single integrated package.
