Latest Patents

One of his latest patents is titled "Method and apparatus for data recovery in a digital data stream using data eye tracking." This invention describes a data recovery system for a serial digital data link that 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, determined by clock pulses generated by the phase shifter, and recovers digital data according to a predetermined decision criterion. The compare logic compares the output of the data sampler according to a predetermined method. The phase controller uses the output of the compare logic to generate phase control signals, while the phase shifter utilizes these signals to create three different phase clocks from the input clock.

Another significant patent is "Data sampling method and apparatus with alternating edge sampling phase detection for loop characteristic stabilization." This invention provides a method and apparatus for 2× oversampling of data that has jitter. It includes a clock and data recovery device featuring an alternating edge sampling binary phase detector, which stabilizes loop characteristics in various jitter environments. This technology can be implemented with minimal hardware overhead and is capable of recovering data at rates of up to 11.5 Gbps from a signal received over a serial link, while consuming no more than 540 mW from a 1.8V supply.
