Abstract: A clock calibrator comprises an input port configured to receive a two-level symbol from a quarter-rate transmitter, the two-level symbol having a period of P unit intervals with a first rising edge launched by one quarter-rate clocks. The clock calibrator includes a clock generator configured to generate four calibration clocks based on the quarter-rate clocks, each calibration clock having the period of P UIs and sequentially having a calibration rising edge delayed by M UIs. The clock calibrator includes a delay-tuner configured to retime the calibration rising edge and a phase detector configured to determine a coarse parameter and a k-th fine parameter based on alignment between the retimed calibration rising edge and the first rising edge with (k?1)M UIs delay. Here P is an integer multiple of 4, M is one less than an integer multiple of 4, and k is selected from 1, 2, 3, and 4.

Abstract: Described herein are systems and methods related to a device including an analog-to-digital converter (DAC) configured to convert a digital signal into an analog signal. The systems and methods can receive an analog signal at a first input, and provide the analog signal to a first output in response to a first clock signal. The first clock signal has a level at least partially dependent on the analog signal. The systems and methods can provide a path to a ground node for the first clock signal in response to a second clock signal. The second clock signal is independent of the analog signal.

Abstract: An apparatus includes control logic coupled to a phase detector circuit and an adjustable delay circuit. The control logic is configured to obtain a state of a first phase of an output signal of a phase interpolator relative to a second phase of a reference signal, and adjust a delay of the reference signal until the second phase matches the first phase. The control logic is further configured to measure a total delay of the reference signal when the second phase matches the first phase, and determine integral non-linearity of the phase interpolator at the first code based on the total delay. The control logic may further calibrate a first code of a phase interpolator based, at least in part, on the integral non-linearity.
