Interface arrangement for IC with full-custom and semi-custom clock domain

摘要

The integrated circuit (IC) includes an analog circuit section (FC) with a first clock domain (TDC1,.., TDCn) leading a clock signal (CKFC), and a digital circuit section (SC) with a clock domain (TDS) leading a second clock signal (CKSC). An interface is inserted between the analog circuit section and the digital circuit section, in such way, that a data signal, which is forwarded by the digital circuit section to the analog circuit section, is sampled first of all with the second clock signal, and is output to the analog circuit section with the first clock signal.
