AC CHARACTERISTICS
Measured in the test circuit of Fig.5; VS = 8.5 V; Tamb = 25 °C.
AC conditions: (1) input signal (Vi) of 815 mV p-p for L = 1, R = 1 (mono) fm = 1 kHz (= 80% modulation). (2) MUX input
signal (Vi) of 1.2 V p-p for L = 1, R = 0 and no DBX; fm = 1 kHz (stereo) and Vpilot = 200 mV p-p. (3) S1 open, unless
specified (without L−R filter); voltage controlled oscillator (VCO) adjusted to 188.8 kHz at Vi = 0 V; values are measured
with an external IF roll-off network (−2 dB at 31.5 kHz = 2fH) at the input (dashed components RS and CS in Fig.5).
All the above conditions apply unless otherwise specified.
