Product Summary
The AM79C874VC-1LP is a Low Power 10/100-TX/FX Ethernet Transceiver. It provides the physical (PHY) layer and transceiver functions for one 10/100 Mbps Ethernet port. The AM79C874VC-1LP delivers the dual benefits of CMOS low power consumption and small package size. Operating at 3.3 V, it consumes only 0.3 W. The AM79C874VC-1LP is IEEE 802.3 compliant. It can receive and transmit data reliably at over 130 meters. It includes on-chip input filtering and output waveshaping for unshielded twisted pair operation without requiring external filters or chokes.
