Function Description 6.1 USB function The F71612A 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 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 / 7 IR Receiver or Transceiver Emulation Device spec. 6.3 Wakeup function The F71612A Supports 2 kinds of wakeup system function, PSOUT and remote wakeup for USB interface.
