Product speciﬁcation

I2C-bus controlled single and multistandard

alignment-free IF-PLL demodulators

TDA9885; TDA9886

12 CHARACTERISTICS

VP =5V; Tamb =25 °C; see Table 20 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

“CCIR line 17 and line 330” or “NTC-7 Composite”; measurements taken in

test circuit of Fig.23; unless otherwise speciﬁed.
