The SPI port programs numerous parameters of the AD9874, thus allowing the device to be optimized for any given application. Programmable parameters include the following: synthesizer divide ratios; AGC attenuation and attack/decay time; the received signal strength level; decimation factor; the output data format; 16 dB attenuator; and the selected bias currents. The bias currents of the LNA and mixer can be further reduced at the expense of the degraded performance for batterypowered applications.
