The 450 kHz IF2 signal after the ceramic channel selection filter is amplified by the
IF AGC amplifier and demodulated. Instead of the demodulated AM audio signal, also the
IF2 signal can be selected on the MPXAM output pin. This IF2 signal can be used for an
external AM stereo decoder. To avoid overdrive of the input stage a detector at the input
drives the RF AGC.
The IF2 signal used for AM IF AGC and demodulation is also used in the limiter circuit for
in-band level detection to generate a level voltage.
The start and slope of the level detector output are programmable with 5 bits and 3 bits
respectively to achieve level information independent on gain variations in the signal
channel.
The output signal from the limiters is used for IF counting in both AM and FM. The
IF count time is automatically controlled to achieve the optimum counting accuracy. The
minimum count time is 2 ms.
