maximum input level1): 3 Vpp (FM) or 1.4 Vpp (AM)
maximum input level: 0.14 Vpp1)
1) For signals above 1.4 Vpp, the minimum gain of 3 dB is switched and overflow of the AD converter may result. Due
to the robustness of the internal processing in FM mode, the IC works properly up to and even more than 3 Vpp. In AM
mode, of course, no AD converter overflow is allowed. As a consequence, in the AM-mode, the maximum input at pins
41 or 43 must not exceed 1.4 Vpp.
