  • Patent number: 5898513
    Abstract: A circuit and method for detecting an edge of the carrier frequency of received data from a remote IR communications device by an Infrared Communications Controller is disclosed. During the receiving of IR signals from a remote IR communications device such as, for example, a TV, VCR or stereo, a frequency window of frequencies above and below a predetermined carrier frequency is opened. If the edge of the carrier frequency of the received data falls within the frequency window, communications are established between the IrCC and the remote IR communications device. If the negative edge of the carrier frequency of the received data does not fall in the frequency window of frequencies, then the system aborts communications. Provisions are made for a ten percent (10%), a twenty percent (20%) frequency window, and a forty percent (40%) frequency window. Other configurations combining various percentage frequency windows are also disclosed as well as methods for generating the frequency windows.
