BTR5 2021 Portable HiFi Bluetooth Earrator

An FPGA is responsible for the transmission and reception of Bluetooth and USB digital audio signals, as well as clock management. In the BTR5 2021, after the Bluetooth signal is processed through the FPGA, jitter is greatly reduced and signal stability is improved, completely solving the problem of different clock rates that exist between the different parts of the audio architecture.

*Tests have shown that Bluetooth music playback quality under LDAC is as good as local playback on a high-end audio player.
