6. Function Description
6.1 USB function
The F71612 communications with host by full-speed USB interface (12Mb/s). It supports 3 suits
endpoint, one control endpoint( endpoint zero) is for bus enumeration, one output endpoint is for
Microsoft Windows Vista IR Receiver or Transceiver Emulation Device command and one input
endpoint is transmit IR information to host.
Endpoint zero is special significance in USB system. It is a control endpoint, and is required by
every device. Only control endpoint accept special setup token that the host transfer command to
device.
During enumeration, host requests GET_DESCRIPTOR to device and device return
information (over in endpoint zero) as what device driver top load. The below table is about F71612

is about Product information, its contents is “eHome Infrared Transceiver. The string table 3 is about
serial number information, its contents is “88636562727801”.
In power function, The F71612 supports remote-wakeup function for USB interface, when PC
system into S3 state. The F71612 decodes IR protocol is the same power key of remote control. The
F71612 is asserted USB interface to wakeup PC system.
The F71612 is compatible for Microsoft Windows Vista IR Receiver or Transceiver Emulation
Device. The F71612 support Microsoft Compatible Device Descriptor and Extended Compact ID
Descriptor are used to tell the host what type of device the emulation is. Vista Emulation Device
driver transmits command over out endpoint1 and device return information over in endpoint1. About
descriptor and command information, reference Microsoft Windows Vista IR Receiver or Transceiver

6.2 IR function
The F71612 Supports 2 IR transceiver functions for blaster application and two IR receivers
with long range frequency and wideband application. The wide-band receiver is necessary to support
IR learning, which is necessary to support 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
same (or wider) range.
About IR information, reference Microsoft Windows Vista IR Receiver or Transceiver Emulation
Device spec.
6.3 Wakeup function
The F71612 Supports 2 kinds of wakeup system function, PSOUT and remote wakeup for
USB interface. The F71612 detect idle state on USB bus for more than 3.0ms, it is into suspend
state.
In Suspend state, the F71612 decodes IR protocol information is the same power key of
remote controller. It asserted PSOUT and USB interface. Reference the below figure

6.4 I2C interface function
The F71612 Supports 1 suit I2C interface to get USB description information and builds 256
bytes RAM to save vendor USB description information. When power is ready, I2C function start to
load USB description into 256 bytes RAM, and expect host requests GET_DESCRIPTOR to F71612
