They want the input to be high enough so limiting occurs after the low-pass filter. That seems to happen with their test signal of 100mV RMS input, so your 800mVP-P (around 280mV RMS) is more than sufficient.
There may not be a maximum limit, but I can't see any radio's discriminator output giving you more than a few volts RMS. The real limiting factor is the power supply voltage on the low-pass filter and how much distortion you will accept.
