1.Low distortion 0.1% typical with a single tuned quadrature coil for 100% modulation.
2.Broad off frequency distortion characteristic
3.Low THD at minimum AFT offset
4.Meter output proportional to signal level
5.Mute function with mute disable and soft deviation mute for LM1965
6.Stop detector with open-collector output for LM1865/ LM2065
7.Adjustable signal level mute/stop threshold, controlled either by ultrasonic noise in the recovered audio or by the meter output
8.Adjustable deviation mute/stop threshold
9.Separate time constants for signal level and deviation mute/stop
10.Dual threshold AGC eliminates need for local/distance switch and offers improved immunity from third order intermodulation products due to tuner overload
11.User control of both AGC thresholds
12.Excellent signal to noise ratio, AM rejection and system limiting sensitivity
13.On-chip buffer to provide gain and terminate two ceramic filters
