Other Parts Discussed in Thread: LMX2572LP, AFE7070, LMX2572
In some of your app notes, TI recommends using the LMX2572LP to generate the LO input to the AFE7070/AFE7071. The output from the LMX2572LP is more or less a square wave. Is a low pass filter needed to eliminate the harmonics? If a low pass filter is recommended, how much should the higher harmonics be suppressed for good operation?
