He is recognized for his contributions to the field of digital signal processing, particularly through his innovative patent related to digital phase locked loops. His work has significant implications for the recovery of stable clock signals in various electronic applications.
Latest Patents
One of Robert L Van Der Valk's key patents is titled "Digital Phase Locked Loop." This invention focuses on recovering a stable clock signal from at least one input signal that is subject to jitter. The digital phase locked loop includes a digital input circuit that receives the input signal, a digital controlled oscillator that generates an output signal at a desired frequency, and a control signal that represents the time error in the output signal. Additionally, it features a stable local oscillator that provides clock signals to the digital controlled oscillator and a tapped delay line that receives the output signal. The tapped delay line consists of multiple buffers, each introducing a delay of less than one clock cycle of the digital controlled oscillator. This innovative design allows for the production of an output signal from a tap determined by the control signal.
