DVB selective AGC amplier
TDA9888TS; TDA9889TS
CHARACTERISTICS
Vi(IF)(rms) = 10 mV frequency fIF = 36 MHz for low IF output of 5 MHz; IF input from 50 via broadband transformer
1 : 1; gain controlled amplifier adjusted to low IF differential output of 2 V (p-p); measurements taken in test circuit of
Fig.11 with external 4 MHz reference signal of 140 mV (RMS); unless otherwise specified.
