Characteristics …continued
VP =5V; Tamb =25 °C; see Table 25 for input frequencies; B/G standard is used for the specication (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
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); not dual mode; measurements taken in test circuit of Figure 50 and Figure 51;
unless otherwise specied.
