Latest Patents

One of Samuel Walker's latest patents is the Serializer Clock Synthesizer. This clock synthesizer utilizes a serializer to convert a parallel data stream into clock signals. The frequency of the synthesized clock is dependent on the bit values of the parallel data stream and the frequency of the reference clock used by the serializer. Rapid tuning of the frequency is achieved by changing the bit values of the parallel data stream, while fine tuning is accomplished by adjusting the frequency of the reference clock. This configuration allows the clock device to generate clock signals with very low jitter, tunable to a fine resolution in frequency, and capable of skewing to an external trigger without glitches. Additionally, it can hop to different frequencies with minimal delays and can be designed at a low cost due to the availability of the serializer in telecommunications applications.

Another significant patent by Walker is the Phase Locked Loop Circuit (PLL). This circuit features a reference terminal for receiving a reference signal and an output terminal for providing an output signal. The PLL includes a phase comparator with first and second inputs, generating a signal based on the phase difference between the inputs. A voltage-controlled oscillator (VCO) is coupled to the phase comparator's output, producing an output signal whose frequency depends on the control input voltage. The circuit also incorporates a feedback path and a bitstream generator that creates pseudo-random bitstreams in response to the reference and feedback signals.
