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 R
TOP 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 Q
o ≥ 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 SC
1 = 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 f
mod = 1 kHz, m = 54%; VIN =10 mV
12. Without a control voltage at pin 3 the SIF input 1 is automatically selected.
