NOTES TO THE CHARACTERISTICS (continued)

3) SCA (SUBSIDIARY COMMUNICATIONS AUTHORIZATION)

α67 =

(spurious)(at9KHZ)

measured with : 81% mono signal; 9% pilot signal; fm=1KHz;

4) ACI (ADJACENT CHANNEL INTERFERENCE)

α114 =

(signal)(at1KHz)

(spurious)(at4KHZ)

α190 =

(signal)(at1KHz)

(spurious)(at4KHZ)

measured with : 90% mono signal; 9% pilot signal; fm=1KHz; 1% spurious signal

The repetition rate must not increase the PEAK voltage.

11) The TDA7340G has a dedicated internal circuitry providing a soft power-on. The I2C bus data

programmation must start after the reference DC level has reached the target Vs/2 value,

otherwise a pop can be generated. The Cref pin and Out pins rise time at power on are riported

in Figg.4, 5, 6 for Cref values of 4.7uF, 10uF, 22uF.

12) The CDL- and CDR- can be shortcircuited in applications providing 3 wires CD signal.

13)The AGND and DGND layout wires must be kept separated. A 50

Ω resistor is recommend to be put

as far as possible from the device.
