Abstract
A serial data receiver circuit included in a computer system may include both an analog and an ADC-based receiver circuit. A front-end circuit generates different equalized signals based on received signals that encode a serial data stream that includes multiple data symbols. During startup of a communication channel, phase information generated by the analog receiver circuit may be used to generate clock signals for the ADC-based receiver circuit. After a period of time, the ADC-based receiver circuit can generate its own phase information to be used in the generation of the clock signals.
