The counter provides accurate and low-power real-base signals. Digital signals are signals composed of specific coding rules and require special decoding chips to process and finally convert into familiar sounds. At this time, in order to maintain audio synchronization, an external Yangxing Technology active crystal oscillator YSO110TR 12.288MHZ is selected. The voice data is divided into left and right channel data. The LRCK (sampling clock) clock is generally 16KHZ, 32KHZ, and 48KHZ; the system's main clock MCLK (oversampling clock).

What advantages can the YSO110TR series bring?
YSO110TR is equipped with audio CMOS and display interface, supports multi-audio channel function; it also has multi-format audio codec function, which can meet the recording, storage and other functions of the audio system. It has small size, low energy consumption, high integration, 1.8-3.3V wide voltage, can refer to the output current under different voltages, simplifies circuit design, does not require peripheral oscillation circuit, and has an industrial-grade operating temperature of -40-85℃, strong environmental adaptability, and can meet the needs of different customers.
