An integrated circuit radio receiver includes radio frequency ("RF") front
end circuitry for receiving and transmitting digital data received
through a wireless interface. A baseband processor is operable to process
the digital data received through the wireless interface. A first logic
is operable to provide a first level of digital filtering for a first
received digital data signal format. A second logic is operable to
provide the first level of digital filtering and derotation for a second
received digital data signal format. A third logic is operable to provide
a second level of digital filtering for a third received digital data
signal format wherein the second level of digital filtering is reduced in
comparison to the first level of digital filtering. Selection logic is
operable to select between the first, second and third logic for
processing the digital data received through the wireless interface.
