摘要: A repeater includes a clock-and-data recovery element and a phase interpolator to extract an embedded clock frequency from a data stream. The phase interpolator determine a frequency offset and sends such offset as phase interpolator codes to a filter and scaler. The filtered, scaled phase interpolator codes are used to produce a reference clock frequency for retransmission.
