Title:
REFERENCE-LESS FREQUENCY DETECTOR WITH HIGH JITTER TOLERANCE
Document Type and Number:
WIPO Patent Application WO/2017/071003
Kind Code:
A1
Abstract:
An apparatus, comprising a first sampling circuit configured to sample a clock signal according to a data signal to produce a first sampled signal, a second sampling circuit configured to sample the clock signal according to a delay signal to produce a second sampled signal, and a control circuit coupled to the first sampling circuit and the second sampling circuit, wherein the control circuit is configured to perform a not-and (NAND) operation according to the first sampled signal and the second sampled signal to produce an activation signal for activating a frequency adjustment for the clock signal.
