A 3.3 V 51.84 Mb/s 16-CAP transceiver for ATM-LANs

A single-chip 51.84Mb/s transceiver is for use in an ATM-LAN system that utilizes carrierless amplitude modulation/phase modulation (CAP). Specifically, the transceiver is for use in the 16-CAP transmission scheme recently chosen by the technical committee of the ATM forum as the ATM-LAN physical layer interface standard for 51.84Mb/s transmission with category 3 unshielded twisted-pair (UTP) wiring. 16-CAP is attractive because it provides this high-data rate with a voice-grade UTP cable, while its bandwidth utilization is still below 26MHz. This eliminates potential problems with FCC electromagnetic compatibility requirements above 30MHz.
