A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal... Agent: Procopio, Cory, Hargreaves & Savitch LLP

20070002990 - Data recovery using data eye tracking: A data recovery system for a serial digital data link includes a data sampler, compare logic, a phase controller, and a phase shifter. The data sampler samples input data three times in a bit time which time is determined by clock pulses generated by the phase shifter, and recovers digital... Agent: Perkins Coie LLP

20070002989 - Method and system for link jitter compensation including a fast data recovery circuit: A method and apparatus, in some embodiments the apparatus includes a sampler, using a plurality of sampling clocks, to sample a first set of data of an incoming data signal to determine a first phase shift indicator and to sample a second set of data of the incoming data signal... Agent: Buckley, Maschoff, Talwalkar LLC

20070002991 - Adaptive elasticity fifo: Disclosed is a method for minimizing the buffer size of an elasticity FIFO queue when synchronizing data between two clock domains. Data communication is typically sent by a transmitter device to a receiver device. The transmitted data signal includes an embedded clock signal and null data characters, as specified by... Agent: Lsi Logic Corporation

20070002992 - Method and apparatus for automatic clock alignment: The present invention synchronizes signals generated and used in different clock domains. The invention is applicable to a CDR circuit in which phase adjustment of a multiphase clock to the phase of incoming data is implemented by controlling phase offsets from the PLL frequency relative to data sampling points Si... Agent: Synnestvedt & Lechner LLP-agere

20070002993 - Clock data recovery loop with separate proportional path: A clock data recovery loop that can be used over a wide range of data rates and maintain second-order behavior includes a nonlinear (e.g., Bang-Bang) phase detector, a charge pump, an RC loop filter, and signal generator (e.g., a voltage controlled oscillator (VCO)). At low data rates, the loop may... Agent: Fish & NeaveIPGroup

20070002994 - Clock jitter estimation apparatus, systems, and methods: Apparatus, systems, methods, and articles may operate to estimate an amount of jitter associated with a clock at an output of a digital phase-locked loop (DPLL), wherein the DPLL includes a phase frequency detector (PFD). The estimate may be made by sensing periods of timing coincidence between an up signal... Agent: Schwegman, Lundberg, Woessner & Kluth, P.A.

20070002995 - Control system for electric motor car: A control system for centrally controlling information related to an electric motor car and effectively using power for the electric motor car involves a VVVF inverter, a CVCF inverter, a fuel cell, a power storage unit, and a power management unit that centrally controls power of the electric motor car....
