Notes: 1. This parameter is given as an application information and has not been tested during production.  
2. In VCR mode, the VIF- and SIF path is switched off.  
3. The adjustment of the turn over point (delayed tuner AGC) with the external resistor RTOP or external voltage VTOP is  
possible.  
4. Resonance circuit of VCO (fo = 38.9 MHz): CVCO = 8.2 - 10 pF,  
Coil LVCO with unloaded Q-factor Qo ≥ 60 for an oscillator voltage ≥ 100 mVRMS at pin 20 - 21  
(e.g., TOKO® coil 7 KM, 292 XNS - 4051Z).  
5. The oscillator drift is related to the picture carrier frequency, given that the external LC circuit is temperature-compensated.  
6. α (1.07) = 20 log (4.43 MHz component/1.07 MHz component); α (1.07) value related to black-white signal  
input signal conditions: picture carrier = 0 dB, colour carrier = –6 dB, sound carrier = –24 dB.  
7. Without external control at pin 13 the IC automatically operates in mode 1:  
negatively modulated video-IF signals and FM/NICAM sound signals.  
8. Without a control voltage at pin 19 the falling AFC curve is automatically selected.  
9. With an open circuit at pin 14 the L’ switch is not active.  
10. Picture carrier PC = 38.9 MHz; sound carrier SC1 = 33.4 MHz, SC2 = 33.16 MHz;  
PC/SC1 =13 dB; PC/SC2 = 20 dB; PC unmodulated (equivalent to synchronous peak level).  
11. Sound carrier SC = 32.4 MHz, modulated with fmod = 1 kHz, m = 54%; VIN =10 mV  
12. Without a control voltage at pin 3 the SIF input 1 is automatically selected.
