48、and 5302, which resonate at 500kHz and 425kHz respectively.The resonators are switched by transistors 7309 and 7316, controlled by the OZ_SW line from the port expander 7406. The reason for 2 frequencies is to avoid tuner disturbances in the AM-band. The oscillator signal is shaped to square wave wi

49、th 7312-2, afterwards buffered and fed to the amplifier modulators (ROZ to the right channel, LOZ to the left). One channel gets inverted clock to balance supply loading. Modulator The modulator forms the pulse width modulated signal. For each channel a seperate modulation is required. Power FETs The FETs require drivers which supply the gates. One for the high-side-FET and one for the low-side-FET. Because of the different supply voltages also an additional level shifter is necessary per driver. Output filter The output filter
