The NetPHYTM 4LP device is a highly integrated, low power 10BASE-T/100BASE-TX/FX Quad Ethernet transceiver. The NetPHYTM 4LP device includes integrated RMII, ENDECs, Scrambler/Descrambler, and full-featured Auto-Negotiation with support for Parallel Detection and Next Page. Port 3 can be configured as a 100BASE-FX transmitter to output an NRZI PECL level signal. Each receiver has an adaptive equalizer/DC restoration circuit for accurate clock/data recovery on the 100BASE-TX signal at different cable lengths and can perform to 125 m and beyond. The NetPHYTM 4LP device operates on a 3.3 V supply and offers 5 V I/O tolerance for mixed signal designs. Power consumption is 1.3 W typical for the device, or 0.3 W per port using 1:1 magnetics. The NetPHYTM 4LP device can use 1.25:1 magnetics, which de creases transmit power consumption and reduces device power consumption to 1.2 W typical. The NetPHYTM 4LP device offers an optimized pinout for network applications. RMII pins can be routed di-
