AC Characteristics (Cont’d): (VS = 8.5V, TA = +25°C, AC Conditions: (1) Input signal (Vi) of
815mVP–P for L = 1, R = 1 (mono), fm = 1kHz (80% modulation); (2)
MUX input signal (Vi) of 1.2VP–P for L = 1, R = 0 and no dbx, fm = 1kHz
(stereo) and Vpilot = 200VP–P; (3) S1 open, unless specified (without
L – R filter), VCO measured with an external IF roll–off network (–2dB
at 31.5kHz = 2fH) at the input. All the above conditions apply unless
otherwise specified)
