WebIt is shown that extensive testability can be implemented in a high data-rate Serdes. The paper describes the bench-test and characterization features, as well as wafer and production test considerations. The Serdes is compliant to IEEE 802.3ap. The DFT features include IEEE 1149.6 AC boundary scan, PRBS generators and checkers. WebTherefore, the multi-level PRBS signal to be generated should comply with conventional PRBS checkers for binary signals and also provide the required characteristics of binary signals. The required characteristics of the test signal received in the PRBS checker are a specific frequency of zero crossings and a uniform distribution of symbols.
