【 摘 要 】

References(19)Multiple-converter synchronization (MCS) is essential for the reliability of ultra-fast time-interleaved analog-to-digital conversion (UF-TIADC) systems or instruments. In this paper, a novel and versatile solution based on phase-sifting approach is proposed in detail for generalized systems. And then, the instantiation design and test are carried out in a 20GSPS TIADC system consisted of four universal 5GSPS ADCs. The results show that the proposed solution is effective on solving the MCS issue and provides a solid timing foundation for further data processing in UF-TIADC systems. Moreover, it offers a practical reference for the MCS implementation of higher-speed sampling systems or instruments.
