A communication device is capable of supporting communication compliant
with a Dual-Mode 2.5G and 3G interface baseband-radio frequency interface
standard and comprises a data interface operably coupled to a number
sub-systems and a clock circuit generating a plurality of clock phases
for supporting communication there between. At least one of the number of
sub-systems comprises a line driver and a line receiver; wherein the
communication device is characterised in that the line receiver
determines an end of a received data frame sent across the data interface
and in response thereto switches itself off.
