Sub-Baudrate Sampling at DAC and ADC for Next Generation 200G Systems
23 September 2018
We investigate generation and detection of signals with baudrate above the DAC and ADC sampling rates. We demonstrate 112 GBd OOK with 88 GS/s DAC and 92 GS/s ADC; as well as 100 GBd PAM4 with under 90 GS/s DAC.
