Patent ID: 8694837

Claim:
A system comprising: a filter circuit configured to (i) receive, from a network device, an analog signal having jitter, (ii) generate an equalized signal based on digital feedback signals and the analog signal, and (iii) generate a recovered data signal based on the equalized signal, wherein the recovered data signal includes data transmitted by the network device to the system; an error module configured to generate an error signal based on (i) the equalized signal and (ii) a threshold signal; and a measurement module configured to generate a plurality of signals based on (i) the recovered data signal, and (ii) the error signal, wherein the plurality of signals include the digital feedback signals and eye characteristic signals, wherein the eye characteristic signals indicate characteristics of an eye diagram of the recovered data signal, and wherein the measurement module is configured to generate the digital feedback signals to reduce an amount of the jitter in the eye diagram of the recovered data signal.
