Notes to the characteristics  
1. Spurious intercarrier AM: m = (AB)/A (wherein A = signal at sync; B = signal with 100 % picture modulation.)  
2. AF2 signal can be adjusted by V6  
3. For larger current: RL > 2.2 k(pin 9 or 10 to GND) in order to increase the bias current of the output emitter follower.  
4. If not used, pin 6 should not be connected.  
5. Automatic frequency control (AFC) of the vision carrier reference circuit (pins 14 and 15) for reducing spurious video  
signals in the stereo/dual sound modes. The factor of reducing FTR at a deviation fVC specifies the ratio of spurious  
signals with/without tracking function.
