Popis: This paper uses a 3-bit ADC to blindly sample the received data at 3× the baud rate to recover the data. By moving from 2× to 3× sampling, we reduce the required ADC resolution from 5-bit to 3-bit, thereby reducing the overall power consumption by a factor of 2. Measurements from our fabricated test chip in Fujitsu's 65nm CMOS show a high frequency jitter tolerance of 0.19UIpp for a 5Gbps PRBS31 with a 16" FR4 channel.
