FM2399
FM2399 is a reverberation processing chip, the chip uses CMOS technology, with digital-to-analog, digital-to-analog conversion function and high sampling frequency, but also has a built-in 44K memory. The digital processing part generates a delay time. The system clock is generated by a built-in voltage-controlled oscillator, a feature of the digital processing circuit, which makes the frequency easy to adjust.
The advantage of FM2399 is that it has a very low distortion factor (THD less than 0.5%) and noise (NO<-90dBV), so it can output a high-quality audio signal. In pursuit of a simpler PCB layout and lower cost, the pin arrangement and application circuit of the FM2399 have been optimized.
