A receiver (100) includes a mixing digital-to-analog converter (DAC)
(120), a direct digital frequency synthesizer (DDFS) (116), and a clock
circuit (114). The mixing DAC (120) includes a radio frequency (RF)
transconductance section (124) and a switching section (128). The RF
transconductance section (124) includes an input configured to receive an
RF signal. The switching section is coupled to the RF transconductance
section (124) and includes inputs, configured to receive bits associated
with a digital local oscillator (LO) signal, and an output. The DDFS
(116) includes outputs, configured to provide the bits associated with
the digital LO signal to the inputs of the switching section (128), and a
first clock input, configured to receive a first clock signal that sets a
sample rate for the digital LO signal The clock circuit (114) is
configured to provide the first clock signal to the first clock input of
the DDFS (116) at a frequency that is based on a selected channel.
