摘要: A high-linearity Phase Interpolator based Clock and Data Recovery (CDR) circuit for use in a multi-standard Serializer/Deserializer (SerDes) is provided. By interpolating at a high, fixed frequency for all supported data rates and then dividing the output clock down to the appropriately frequency for each standard, the Phase Interpolator can provide for maximum phase linearity while reducing its sensitivity to noise.
