Abstract
- This paper proposes using a 3-bit ADC to blindly sample the received data from a channel with 20 dB loss at Nyquist at 3x the baud rate. By moving from 2x to 3x 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 test chip fabricated in Fujitsu's 65 nm CMOS show a high frequency jitter tolerance of 0.25 UIpp for a 5 Gb/s PRBS31 with a 60" FR4 channel. [ABSTRACT FROM AUTHOR]
