Characteristics …continued

VP =5V; Tamb =25 °C; see Table 24 for input frequencies; B/G standard is used for the speciﬁcation (fPC = 38.375 MHz;

fSC = 32.875 MHz; PC / SC = 13 dB; fAF = 400 Hz); input level Vi(IF) = 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: Vestigial SideBand (VSB); 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”;

internal Nyquist slope switched on (W7[0] = 0); measurements taken in test circuit of Figure 51; unless otherwise speciﬁed.
