摘要： A phase locked loop generates an output corresponding to a source synchronous input and an input link clock signal. A phase locking feedback system receives the input and an input link clock signal and detects phase deviations between the output and the input. The phase locking feedback system also adjusts an adjusted clock signal based on the phase deviations thereby causing the phase locking feedback system to generate the output so that the output has a steady phase relationship with the input. A first mechanism causes the phase locking feedback system not to track phase deviations between the output and the input upon occurrence of a first predefined event, thereby maintaining the adjusted clock signal at a current state.

摘要： Techniques and apparatus for testing phase rotators for detecting defective tap weights are provided. Phase rotator test logic may include a master phase rotator to cycle the phase of a clock signal distributed to operational phase rotators through an entire cycle of phases (e.g., an entire 360 degree rotation). Each operational phase rotator should respond with an equal but opposite phase shift in order to maintain phase lock. Thus, after sweeping, each tap weight is exercised, which may help ensure defective tap weights in any (e.g., quadrant) are detected during testing.

摘要： The present invention generally relates to centering a clock edge at or near the center of a data eye. Data may be sent from a first device to a second device in conjunction with a clock signal. A phase rotator operating in an external clock domain governed by the clock signal received at the second device may rotate the phase of the received clock signal to sample data. The data sampled in the unstable external clock domain may be transferred to a stable local clock domain for analysis. Feedback may be provided from the stable clock domain to the phase rotator to adjust the phase of the received clock signal to position an edge of the clock signal at or near the center of the data eye.
