LHY AUDIO Digital Interface Module

This LHY Audio digital interface module converts a digital signal via various inputs into an I2S signal via an output on a PCB connector. It features an AKM AK4118 chip and a QCC5125 Bluetooth receiver chip. The AK4118 chip enables this module to accept 24bit 192kHz streams via its coaxial SPDIF, AES/EBU and Toslink optical inputs, while the QCC5125 Bluetooth 5.1 receiver chip enables it to receive high-resolution Bluetooth codecs: aptX, aptX Adaptive and aptX HD. The PCB also features a source selection button and soldering pads for an external button.

There is also a small OLED display showing information about the signal being processed, such as the input source, signal format and sampling rate. A pushbutton on this small screen also allows the input source to be changed. And a remote control is provided for convenient distance operation.

The LHY Audio AK4118 digital interface module is powered by 5V DC.
