Notes
1. This parameter is given as an application information and it is not tested during production.
2. The oscillator drift is related to the picture carrier frequency, at external temperature-compensated LC circuit
3. a(1.07) = 20 log (4.43 MHz component/ 1.07 MHz component);
a(1.07) value related to black-white signal
input signal conditions: picture carrier
0 dB
color carrier
–6 dB
sound carrier –24 dB
4. 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 sync peak level)
5. Sound carrier SC = 32.4 MHz, modulated with f_mod = 1 kHz, m = 54%; v_in = 10 mV
6. Without control voltage ‘High Level’ mode is automatically selected
7. For L’: AFC is adjustable with external potentiometer
