I'm evaluating this part for use in a system, and right now I am working through the frequency plan. Can anyone tell me where in frequency the LO is relative to the RF (in the 56 MHz bandwidth case). Is the LO is only 56 MHz away from the highest (or lowest) RF frequency? What is the ADC speed? I could not find any of this information in the datasheet. I can see from the block diagram that no filtering takes place inside the transceiver prior to mixing, so I know there is not an image reject filter built in. Thank you.
