Jingxun 863M Wireless Earphone Chip User Manual
The 863M chip integrates both transmitter and receiver functions on a single PLL‑based design, offering stable frequency, multiple channel selection, stereo encoding, and built‑in charging control. The transmitter requires only a control chip and PLL, while the receiver needs only a stereo decoding chip, keeping the circuit simple and low‑cost. Transmission range exceeds 200 m.
The manual provides detailed technical specifications such as operating voltage (2.2‑5.5 V), current consumption (≤3 mA CPU, ≤80 mA TX, ≤60 mA RX), and charging behavior (0.2 C charge current, stop at 2.8 V or 6 h). It also explains basic operation steps for powering on, frequency switching, signal detection, mute control, and charging modes. This manual is written in Chinese.
