Although the common Bluetooth speakers on the market are relatively cheap, their sound quality is far from satisfactory and cannot meet people's pursuit of high-quality sound. The fundamental reason is that the Bluetooth speaker box is too small and the speaker is too small, resulting in a serious lack of bass; the resonance of the plastic box causes muddy sound; the speaker is too close and the near-field sound is too narrow, etc. This design reference integrates the MaxxAudio sound enhancement chip NPCA110P, which greatly improves the problems of muddy sound, insufficient bass, and narrow near-field sound.
Supports data monitoring and PD packet injection on CC1 and CC2 lines, and voltage and current detection on VBUS and VCONN.
It can be powered via a USB port and has an LCD interface for standalone use without a PC. ERASynth Micro uses a dual-loop PLL architecture to provide fast frequency switching and fine tuning resolution. Frequency, amplitude and pulse modulation capabilities are also available.
