Item description:
This circuit is the core of BH1417F phase-locked loop FM stereo application-specific integrated circuit.The integrated circuit is made up of improve the signal-to-noise ratio (S/N) pre-emphasis circuit, prevent over modulation limiter circuit, control signal input signal frequency of the low-pass filter circuit (LPF), produce the stereo composite signal, FM stereo modulation circuit launch phase lock loop (PLL) circuit, etc.BH1417F frequency characteristic is excellent, it can reach 40 db separating degree, transmission quality can be comparable to the local FM radio.Part due to the high frequency oscillation frequency synthesis circuit is adopted, so the oscillation frequency is very stable, and can easily change the transmission frequency.And it sets up the pre-emphasis circuit, limiting circuit and low-pass filter can significantly improve the sound quality, its total harmonic distortion is 0.3%, the RF output level is 100 db.
