Multistandard dual carrier stereo sound decoder
TDA9873H
Notes
1.
Input level for IF intercarrier from an external generator with 50
source impedance, f
mod
= 400 Hz, 27 kHz
deviation of audio references: level for SC1 is 50 mV (RMS), SC1/SC2 = 7 dB. S/N and THD measurements are
taken at 50
μ
s de-emphasis.
For higher input voltages a series resistor connected to pin 25 is recommended.
The tolerance of the reference frequency determines the accuracy of the FM demodulator centre frequencies,
maximum FM deviation, pilot window width and pilot window mid-frequency error.
