Samsung patents clock signal adjustment for faster data transmission
This patent describes a transmitter component that uses a phase interpolator to fine-tune internal clock signals. It adjusts the timing of data signals based on control signals from the driver to ensure accurate transmission.
In the filing’s own words
Disclosed is a transmitter including a phase interpolator configured to generate an internal four-phase clock signal based on a four-phase clock signal including a first clock signal, a second clock signal, a third clock signal, and a fourth clock signal, a data path configured to generate a path data signal based on a data signal and the internal four-phase clock signal, a driver configured to generate a transmission data signal based on the path data signal and the four-phase clock signal. The driver is further configured to provide the phase interpolator with a control signal indicating a first phase state, a second phase state, or a third phase state based on a first path bit signal of the path data signal, the first clock signal, and the fourth clock signal. The phase interpolator is further configured to interpolate the internal four-phase clock signal based on the control signal.
What exactly they claim (claim 1)
1. A transmitter comprising: a phase interpolator configured to generate an internal four-phase clock signal based on a four-phase clock signal including a first clock signal, a second clock signal, a third clock signal, and a fourth clock signal; a data path configured to generate a path data signal based on a data signal and the internal four-phase clock signal; and a driver configured to generate a transmission data signal based on the path data signal and the four-phase clock signal, and provide the phase interpolator with a control signal indicating a first phase state, a second phase state, or a third phase state based on a first path bit signal of the path data signal, the first clock signal, and the fourth clock signal, and wherein the phase interpolator is further configured to interpolate the internal four-phase clock signal based on the control signal.
