Latest Patents

One of Yasser's latest patents focuses on phase alignment between phase-skewed clock domains. This invention addresses the challenge of compensating for phase offsets between different sets of circuitry that operate under varying synchronous clock domains. The transmit (TX) circuitry of one domain is designed to send a pattern signal, such as a pseudo-random bit sequence, to the receive (RX) circuitry of another domain. The RX circuitry then cycles through various phase-shifted RX clock signals to identify which selected clock signals yield valid RX pattern signals. This allows the RX circuitry to select an appropriate phase-shifted clock signal for processing incoming RX data signals.

Another significant patent involves methods and apparatus for detecting and decoding adaptive equalization training frames. This invention provides a systematic approach for detecting training frames characterized by a specific frame marker composed of binary ones and zeroes. The process includes shifting the received data, modifying it by inserting binary values, and applying a logic function to identify discrepancies in corresponding bit positions. The frame marker is detected when the output of the logic function indicates a specific binary value in the middle of a string of another binary value. The training frames are subsequently decoded based on the distance between the frame marker's approximate center and a predefined binary value.
