INTEGRATED CIRCUIT AND SERDES DEVICE HAVING EYE OPENING MONITOR

摘要

An integrated circuit according to an embodiment of the present invention includes: an internal circuit; and an eye opening monitor (EOM) configured to measure an eye diagram of a predetermined point of the internal circuit, wherein the EOM includes: a digital to analog converter configured to receive reference voltage data and to output first and second parent reference voltages; and a comparator configured to receive the first and second parent reference voltages and first and second input voltages outputted from the internal circuit and to compare the first and second input voltages with target reference voltages divided from the first and second parent reference voltages by varying a driving capability according to size information data.
