Daughterboard ?
If you look at the LFRX the input consists of AD813x fully differential
amplifier with unity gain and a input impedance of 50 ohm. I am not sure if there are diodes which limit the signal swing, maybe looking at the schematics can help you with this.
From what I
understand the LFRX and Basic-RX are very similar, so the same rules
for safety apply. I have used 2V pk-pk voltages as input from a signal with a
source impedance of 50 ohms without any problems. If your source
doesn't have a 50 ohm source impedance, the DC voltage will be
incorrect by about 106mV (there are some threads which discuss this issue in greater detail).
