Abstract :
This paper describes a serial 10 gigabit Ethernet transceiver IC. To the extent of our knowledge, this is the first report of such a device on bulk CMOS. It uses a novel analog phase rotator in each of the 5 clock-and-data recovery (CDR) units for an efficient implementation of multi-channel receiver circuits. A substantial amount of digital logic is present on the chip to perform the encoding, decoding, FIFO, MDIO etc. functions as specified by the 802.3ae standard. Sub-picosecond RMS jitter is nevertheless achieved in such a hostile environment. The chip is implemented in a 0.13/spl mu/m digital CMOS process and dissipates 1.5 watts under a 1.5-volt power supply.
