Patent number: 7958294Abstract: An integrated circuit having a plurality of data transceivers positioned on opposite ends of the integrated circuit is disclosed. The integrated circuit comprises a first plurality of data transceivers positioned in a column on a first end of the integrated circuit and a second plurality of data transceivers positioned in a column on a second end. A circuit is preferably positioned between the first plurality of data transceivers and the second plurality of data transceivers. The circuit could comprise, for example, circuits for implementing a programmable logic device. The circuitry of the plurality of data transceivers is also preferably arranged such that analog circuitry is positioned closer to an end of the integrated circuit than the digital circuits to reduce interference with the analog circuits. According to another aspect of the invention, the data transceivers are formed on layers to reduce the amount of interference.Type: GrantFiled: November 19, 2004Date of Patent: June 7, 2011Assignee: Xilinx, Inc.Inventor: Thomas Anthony Lee

Patent number: 7558552Abstract: Various embodiments of the present invention relate to circuits for and methods of generating a bias current for a plurality of data transceivers on an integrated circuit. According to one embodiment, an integrated circuit having a plurality of data transceivers comprises a first data transceiver receiving a reference voltage. A plurality of data transceivers are preferably coupled to the first data transceiver, where each the data transceiver of the plurality of data transceivers receives a reference current based upon the reference voltage from the first data transceiver. According to alternate embodiment of the invention, an external resistor is coupled to a data transceiver to generate a fixed bias current in addition to a variable bias current. A method of generating a bias current for a plurality of data transceivers is also disclosed.Type: GrantFiled: November 19, 2004Date of Patent: July 7, 2009Assignee: XILINX, Inc.Inventor: Thomas Anthony Lee

Patent number: 7536666Abstract: The various embodiments of the present invention relate to coupling clock signals between a plurality of data transceivers. According to one embodiment, a clock routing circuit having data transceivers comprises a clock bus interface and a first data transceiver coupled to the clock bus interface to receive a clock signal from the clock bus interface. A clock bus coupled to receive the clock signal enables the transfer of the clock signal to an adjacent data transceiver. According to other embodiments, various clock buses and interfaces enable routing clock signals between various circuits of the integrated circuit.Type: GrantFiled: November 19, 2004Date of Patent: May 19, 2009Assignee: Xilinx, Inc.Inventors: Thomas Anthony Lee, James P.

Patent number: 7248157Abstract: In one aspect, a phone-interface device determines whether a problem has occurred at a control panel by determining whether a signal from the control panel has been received, and when a signal has not been received within a period of time, the phone-interface device transmits an error message to a monitoring station. In another aspect, the control panel determines whether a problem has occurred at the phone-interface device by determining whether a signal from the phone-interface device has been received, and when a signal has not been received within a period of time, the control panel transmits an error message to a user. In another aspect, the phone-interface device contains memory to buffer data transferred between the control panel and a monitoring station. In this way, a high-speed connection between the phone-interface and the monitoring station can be accommodated while using a lower-speed connection between the phone-interface device and the control panel.Type: GrantFiled: May 1, 2001Date of Patent: July 24, 2007Assignee: Interactive Technologies, Inc.Inventors: John Todd Bergman, Kurt Hasselfeldt, Thomas Anthony Lee, Eric W. Lofstad, Brian Karl Seemann

Patent number: 7184466Abstract: A data conveyance integrated system that can be utilized in a base station and/or end user devices in a wireless communication system. The integrated system includes first and second integrated circuits (ICs). The first IC includes a first serial-deserial (SERDES) module, a transmit radio frequency module, and a receive radio frequency module. The transmit and receive radio frequency modules provide the wireless communication between the base stations and end user devices. The second IC includes a second SERDES module and a programmable logic fabric programmed to implement one or more wireless communication functions. Accordingly, the programmable logic fabric generates outbound digital signals from data (e.g., video, audio, control, or text data) provided to the device, and/or processes inbound digital signals to recapture the originally transmitted data. Thus, base stations and/or end user devices within a wireless communication system can be readily reconfigured.Type: GrantFiled: September 12, 2002Date of Patent: February 27, 2007Assignee: Xilinx, Inc.Inventors: Brian K. Seemann, Brian T. Brunn, Normand T. Lemay, Jr., Daniel J. Ferris, III, Thomas Anthony Lee, James M. Simkins, David B. Squires

Patent number: 7054414Abstract: A phone-interface device receives a wireless signal from a control panel. The wireless signal encodes information regarding a system condition that has occurred in a facility. The phone-interface device communicates the system condition to a monitoring station. The phone-interface device receives its electrical power from the telephone line or from an energy storage device. In another aspect, the phone-interface device receives a provisional-alarm signal command from a control panel. The phone-interface device determines whether a disarm command has been received from the control panel. When a disarm command has not been received before expiration of a period of time, the phone-interface devices sends an alarm condition to a monitoring station.Type: GrantFiled: May 1, 2001Date of Patent: May 30, 2006Assignee: Interactive Technologies Inc.Inventors: John Todd Bergman, Kurt Hasselfeldt, Thomas Anthony Lee, Eric W. Lofstad, Brian Karl Seemann
