Figure 2. MB4104 TEST CIRCUIT : *1 VCO free running frequency should be adjusted at 19.000 KHz +10 Hz. *2 The value is 100 FF when SC and HCC are measured. higher than Vcc is applied to pin 7, a 10 KQ. resistor should be inserted. *4 When pin 13 = GND, or is lower than 0.4 V, the device is in an audio mute mode.
