The quadrature detector is similar to a PLL. There is an  
internal oscillator running at the IF frequency and two  
detector outputs. One is used to deliver the audio signal and  
the other one is filtered and used to tune the oscillator.  
The oscillator frequency is set by an external resistor at

±8.4 kHz due to an internal filter capacitor. This is verified in  
Figure 13. For some applications it may be desirable that the  
audio bandwidth is increased; this is done by reducing R .  
Reducing R widens the detector bandwidth and improves

455 kHz would require a current of around 50 µA. The pin  
voltage (Pin 16 in the 32 pin QFP package) is around 655mV  
giving a resistor of 13.1 kΩ. Choosing 12 kΩ as the nearest  
standard value gives a current of approximately 55 µA. The

resistor value of (1.5 – 0.655)V/5.0 µA = 169 kΩ. Choosing  
150 kΩ would give a tuning current of 3/150 k = 20 µA. From  
Figure 9 this would give a tuning range of roughly 10 kHz/µA
