Latest Patents

One of Flynn's latest patents is focused on circuitry to facilitate testing of serial interfaces. This invention describes a method to test the clock and data recovery functionality of a receiver. The serial interface includes a multiplying phase locked loop (MPLL) clock generator, a transmitter, and a receiver. The MPLL clock generator generates two clock signals and can vary the phase and frequency difference between them. During testing, the transmitter and receiver can be directly or capacitively coupled, allowing for effective data transmission and reception. The functionality of the receiver is tested by comparing the transmitted data with the received data.

Another significant patent by Flynn addresses reducing power consumption in clock and data recovery systems. This invention provides a clock and data recovery (CDR) system that recovers clock and data information from an analog signal. The CDR system includes an integral path and a proportional path as part of an integral-proportional control loop. The integral path tracks frequency changes, while the proportional path tracks phase changes in the clock signal. By executing the proportional path at a higher clock frequency and the integral path at a lower frequency, the system effectively reduces power consumption.
