A 1.25-GBaud CMOS transceiver with on-chip terminator and voltage mode driver for Gigabit Ethernet 1000Base-X

This paper presents a 1.25-GBaud transceiver chip implemented with 0.35-/spl mu/m CMOS technology, which can be used as an IEEE 802.32 Gigabit Ethernet 1000Base-X physical layer. A voltage mode driver and an on-chip termination circuit reduce signal distortion in the pseudo-ECL serial data stream in the presence of parasitic capacitance and inductance as well as reducing the number of external components. A differential voltage swing of output driver is 1400 mV and power consumption is 510 mW at 3.3 V supply under normal operation.
