FPGA Master Technology

The DX170 utilizes the FPGA-Master technology developed by iBasso. The FPGA-Master, as the audio system controller, directly requests audio data from the SoC, and plays a major role in signal reproduction and maintaining signal integrity. It synchronizes and generates all audio clocks at the same time utilizing two NDK femtosecond oscillators to achieve a fully synchronized single clock source. The FPGA and NDK oscillators also reduce jitter to an extremely low level, building a clean digital audio signal.

CIRRUS CS43131 X 2 DAC Chips

iBasso has featured a Dual DAC chipset on the DX170. The device comes equipped with dual CS43131 DAC chips that provide exceptional performance with ultra-low THD+N and high SNR values. These are 32-Bit DAC chips that provide users with top-quality audio signal decoding!!! Regardless of if you're using the 3.5mm single-ended or 4.4mm balanced output, with diligent tuning and adjustment, the DX170 not only retains the transparency and exquisiteness of CS43131, but also enhances the musicality and realism of the music.
