F71869A
5.8 CIR Function
The F71869A is compatible with Microsoft Windows Vista and Windows 7 IR Receiver or
Transceiver Emulation Device which supports RC6 & QP protocol. It Supports 1 IR transceiver
functions for blaster application and 1 IR receiver with long range frequency and another with wide
band application. In power function, The F71869A supports Vista and Windows 7 wakeup
programming function when the PC is in the S3 state. The F71869A decode IR protocol via the
same Vista and Windows 7 wakeup programming key. The F71869A is asserted PME or PSOUT to

for long range frequency and wideband application. The wide-band receiver is necessary to
support IR learning, IR-blasting and set-top box control.
The long-range receiver is a receiver which has the following characteristics:
1. Works at a distance of 10 meters.
2. Demodulates the signal inside the receiver part
3. Has a BPF which works with carriers from 32-60 kHz.
The wide-band receiver is a receiver part which has the following characters:
1. Works at a distance of approximately 5 centimeters.
2. Does not demodulate the signal inside the receiver part
3. Works with carriers from 32-60 kHz. (Probably doesn’t have a BPF, but still has the
