Clock Frequency Limiter - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240305303 titled 'Clock Frequency Limiter

Simplified Explanation: The patent application describes a receiver circuit that controls the frequency of a clock signal in a computer system. The circuit ensures the clock signal does not exceed a certain threshold frequency by adjusting it accordingly.

  • Front-end circuit generates an equalized signal.
  • Clock generator circuit creates a clock signal using samples of the equalized signal.
  • Measurement circuit monitors the clock signal frequency and activates an indication signal if it exceeds a threshold.
  • Clock generator circuit adjusts the frequency of the clock signal in response to the indication signal.

Key Features and Innovation:

  • Receiver circuit for controlling clock signal frequency.
  • Front-end circuit for equalizing the signal.
  • Clock generator circuit using samples of the equalized signal.
  • Measurement circuit to monitor and adjust clock signal frequency.

Potential Applications:

  • Computer systems.
  • Electronic devices requiring precise clock signals.

Problems Solved:

  • Preventing clock signal frequency from exceeding a threshold.
  • Ensuring stable and accurate clock signal for system operation.

Benefits:

  • Improved system performance.
  • Prevents errors due to high clock signal frequency.

Commercial Applications: Clock signal control technology for computer hardware manufacturers.

Prior Art: Prior art related to clock signal frequency control circuits in computer systems.

Frequently Updated Research: Ongoing research on clock signal optimization and frequency control in computer systems.

Questions about Clock Signal Frequency Control: 1. How does the receiver circuit ensure the clock signal frequency stays within the desired range? 2. What are the potential implications of inaccurate clock signal frequency in a computer system?


Original Abstract Submitted

a receiver circuit that limits the frequency of a clock signal used in a computer system is disclosed. an embodiment of the receiver circuit includes a front-end circuit configured to generate an equalized signal, a clock generator circuit configured to generate a clock signal using a plurality of samples of the equalized signal, and a measurement circuit. the measurement circuit is configured to monitor a frequency of the clock signal and activate an indication signal in response to determining that the frequency of the clock signal exceeds a threshold frequency. in response to activation of the indication signal, the clock generator circuit is configured to set the frequency of the clock signal to a particular frequency.
