This abstract first appeared for US patent application 18890839 titled 'DIGITAL SERIALIZER/DESERIALIZER CIRCUIT AND DATA EYE MONITORING METHOD THEREOF
Original Abstract Submitted
The application disclose a digital serializer/deserializer circuit and a data eye monitoring method thereof. A received analog signal is converted to first digital samples at a first sample rate. The first digital samples are equalized to generate a first equalized signal. A symbol decision signal is generated from the first equalized signal. The received analog signal is converted to second digital samples at a second sample rate. Difference between the first digital samples and the second digital samples is determined, and the first equalized signal and the determined difference are combined to generate a signal processing output. A data eye error rate is determined according to the symbol decision signal and the signal processing output.
