MODEM USING CAPACITIVE INSULATING BARRIER, INSULATING COUPLER, AND INTEGRATED CIRCUIT USED IN THE MODEM |
| 摘要 |
<p>When an insulating coupler having a capacitive insulating barrier is formed on an SOI substrate and the timings of the DSP, AFE, and insulating coupler are synchronized using the DSP operation clock, the line interface circuit is made monolithic. By doing this, a miniature and economical modem device can be realized. <IMAGE></p> |
