MODEM USING CAPACITIVE INSULATING BARRIER, INSULATING COUPLER, AND INTEGRATED CIRCUIT USED IN THE MODEM

摘要

By forming an insulating coupler having a capacitive insulating barrier on a SOI substrate and synchronizing the timings of DSP, AFE, and the insulating coupler by using a DSP operating clock, a line interface circuit can be made monolithic. Thus, a small-size and economical modem can be realized.
