| 1. A system comprising:
a media access controller (MAC); and
a communication device comprising:
a media independent interface (MII) coupled to the MAC to at least one of transmit and receive data at a data rate;
a plurality of data lane interfaces, each data lane interface being capable of at least one of transmitting a serial data
signal to and receiving a serial data signal from a data lane in a device-to-device interconnection; and
a transmitter coupled to the MII to receive data from the MII and coupled to selectively transmit the data to one or more
of the data lane interfaces at a variable rate dependent upon a number of the data lane interfaces to which the transmitter
is transmitting the data, wherein the transmitter is coupled to receive a transmit clock signal having a variable frequency
dependent upon the number of the data lane interfaces actively transmitting a serial data signal.
