Abstract
A 10GBASE-T clocking method that limits EMI and increases SNR, while reducing power and conserving chip space is provided. The method includes simultaneous clocking of transmitters in an analog front end of a 10 gigabit Ethernet. The method includes providing at least two channels to a 10GBase-T analog front end, where the channel has at least a transmitter port and a receiver port, and providing at least two phase interpreters to the analog front end, where each phase interpreter is dedicated to one receiver port. A central clock generator is disposed to distribute a transmit clock to the phase interpreters and to the transmitter ports, where the transmit clock is further provided to the receiver ports from the phase interpreters. Any clock delay between the clock generator and each channel is balanced and clock phases between the channels are matched.
