CONDITIONS

MIN.

TYP. MAX. UNIT

FM1 and FM2 demodulators

Measurements with FM IF input signals of 5.5 MHz and 5.74 MHz with V_{i IF (rms)}= 10 mV (f_mod= 1 kHz, deviation

∆f = ± 50 kHz) at pins 15 and 19 without ceramic ﬁlters, R_S= 50 Ω.

De-emphasis 50 µs and V₅= V_P(B/G standard). Q_L-factor = 11 for resonant circuits at pins 6-7 and 10-11.
