  • Patent number: 6995594
    Abstract: A high-speed serial data transceiver includes multiple receivers and transmitters for receiving and transmitting multiple analog, serial data signals at multi-gigabit-per-second data rates. Each receiver includes a timing recovery system for tracking a phase and a frequency of the serial data signal associated with the receiver. The timing recovery system includes a phase interpolator responsive to phase control signals and a set of reference signals having different predetermined phases. The phase interpolator derives a sampling signal, having an interpolated phase, to sample the serial data signal. The timing recovery system in each receiver independently phase-aligns and frequency synchronizes the sampling signal to the serial data signal associated with the receiver. A receiver can include multiple paths for sampling a received, serial data signal in accordance with multiple time-staggered sampling signals, each having an interpolated phase.

  • Publication number: 20050286669
    Abstract: A system and method is provided for phase interpolator based transmission clock control. The system includes a transmitter having a phase interpolator coupled to a master timing generator and a transmission module. The phase interpolator is also coupled to a receiver interpolator control module and/or an external interpolator control module. When the system is operating in repeat mode, the transmitter phase interpolator receives a control signal from a receiver interpolator control module. The transmitter phase interpolator uses the signal to synchronize the transmission clock to the sampling clock. When the system is operating in test mode, a user defines a transmission data profile in an external interpolator control module. The external interpolator control module generates a control signal based on the profile. The transmitter phase interpolator uses the signal to generate a transmission clock that is used by the transmission module to generate a data stream having the desired profile.

  • Publication number: 20040248552
    Abstract: The invention comprises one or more Interactive Voice Response (“IVR”) computers connected both to the public telephone system, through telephone lines, and, through a private network, to a central processing computer with a voter information database and a separate database of voting results. The IVR computers can identify an individual voter through security information given when the citizen registered to vote; the computers then employ that information to obtain and secure a single, accurate ballot from the voter. The voting-results database is in no way connected to the voter-identification database or identification of the voter. At the close of voting, the invention connects securely to the central office administering the election and sends the tabulated results of all votes.
