MCHStreamer Lite

The MCHStreamer Lite, a simplified version of our MCHStreamer, is a multi-channel asynchronous USB interface that supports a myriad of digital I/O formats and leverages years of XMOS product development to achieve a rock solid performance in all configurations. Packaged on a tiny 40x62mm PCB, the MCHStreamer Lite is a perfect fit for OEM/DIY integration or as a testing tool for your R&D team.

By loading one of the miniDSP-provided firmware packages, MCHStreamer Lite supports I2S, TDM, DSD and PDM data formats for input and output. In addition, optical TOSLINK, ADAT and S/PDIF (coax), are supported for output only. This USB Audio Class 2 (UAC2) compliant interface truly is a powerful tool for audio developers looking to provide an audio interface to PC/MAC/Linux, iOS and Android. It even supports format conversion from PDM signal to I2S for up to 16 MEMS microphones: a neat tool for beamforming algorithm development.
