The primary use for the dual analog input structure is sampling both antennas in a two-antenna diversity receiver. However, Channels A and B may also be used to sample two independent IF signals. Diversity, or dual-channel mode, is limited to 10 MSPS per channel. In single-channel mode, the full clock rate of 20 MSPS may be applied to a single carrier. The AD6600 may be used as a stand-alone sampling chip, or it may be combined with the AD6620 Digital Receive Signal Processor. The AD6620 provides 10 dB25 dB of additional processing gain before passing data to a fixed- or floating-point DSP.
