Abstract :
This paper presents an isolated analog front-end (I-AFE) LSI with built-in isolation function for V.90, 56 kbps modems. The LSI has 1.5 kVrms. AC isolation and analog front-end functions within a 5 mm×4.5 mm die with 0.4 μm SOI CMOS process and a 50 pin TSOP package. The on-chip isolation approach eliminates external isolation devices such as transformers or photo-couplers. A 100 Mbps transmission rate is attained by the on-chip isolator
