Product specication
I2C-bus controlled multistandard alignment-free
IF-PLL demodulator with FM radio
TDA9887TS
12 CHARACTERISTICS
VP =5V; Tamb =25 °C; see Table 21 for input frequencies; B/G standard is used for the specication (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
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 specied.
