Circuit for and method of implementing a bursty clock and data recovery circuit using an eyescan detection circuit

摘要

A circuit for receiving data is described. The circuit comprises a phase detector circuit comprising a detector having a first input configured to receive a sum of an oscillator phase and a phase error, and a second input coupled to an output of a first sample selector; a second sample selector having an input coupled to receive the input data and generate output data; and an eye detection circuit comprising a third sample selector having an input coupled to receive the input data and a comparator for comparing outputs of the second sample selector and the third sample selector to determine how much an eye is open for a plurality of channels. A method of implementing a receiver is also described.
