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 R
4. Resonance circuit of VCO (f
5. The oscillator drift is related to the picture carrier frequency, given that the external LC circuit is temperature-compensated.
6.
7. Without external control at pin 13 the IC automatically operates in mode 1:
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 SC
11. Sound carrier SC = 32.4 MHz, modulated with f
12. Without a control voltage at pin 3 the SIF input 1 is automatically selected.
