Characteristics …continued

VP =5V; Tamb =25 °C; see Table 22 for input frequencies; B/G standard is used for the speciﬁcation (fPC = 38.9 MHz;

fSC = 33.4 MHz; PC / SC = 13 dB; fmod = 400 Hz); input level Vi(VIF) = 10 mV (RMS) (sync level for B/G; peak white level

for L); IF input from 50

Ω via broadband transformer 1 : 1; video modulation DSB; residual carrier for B/G is 10 % and for

L is 3 %; video signal in accordance with “ITU-T J.63 line 17 and line 330” or “NTC-7 Composite”; measurements taken in

test circuit of Figure 26; unless otherwise speciﬁed.
