Latest Patents

Xingdong Dai's latest patents include a "Method and apparatus for continuous-averaging counter-based digital frequency lock detector." This invention provides methods and apparatus for counter-based digital frequency lock detection. The design features a reference counter clocked by a reference clock and a target counter clocked by a target clock. The target counter is n bits, where n is less than the number of bits of the reference counter. A frequency offset violation of the target clock is detected by comparing the value of the target counter to an n-bit counter. Another notable patent is "Phase alignment between phase-skewed clock domains." This invention compensates for phase offsets between different sets of circuitry with varying synchronous clock domains. The transmit (TX) circuitry of one domain transmits a pattern signal to the receive (RX) circuitry of the other domain. The RX circuitry cycles through various phase-shifted RX clock signals to identify which selected clock signals yield valid RX pattern signals.
