PLL stereo decoder (BTSC system)

TEA5582

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 V

i = 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.
