Dual input port (I2S and USB) Audio Module, MQA enabled.
Add a full-featured USB/I2S solution to any high-end audio product. Easy integration into a new or existing product, i.e. Pre Amp, Surround Sound Processor or DAC.
Support for: 44.1, 48, 88.2, 96, 176.4, 192, 352.8 and 384kHz PCM, DSD64/128/256 (Native) and DSD64/128 (DoP).
Full MQA and MQA Studio decoding modes supported (both USB and I2S inputs).
Two input ports: USB input and I2S input, The I2S port allows all supported digital input and network connections to be routed to module for MQA decoding.
Module can be configured as system clock (MCLK) master or slave, allowing easy integration into preferred system architecture for optimum time-domain performance.
Asynchronous USB transfer for optimal timing precision - dual master clocks: one for 44.1, 88.2, 176.4, 352.8kHz and DSD the second for 48, 96, 192 and 384kHz.
I2S input accepts all common sample rates/quantisation resolutions, i.e. 44.1kHz to 384kHz, 16 to 32 bits).
Audio transmitted from module at native rate - easy to add in-house post-processing IP.
Optional support for mobile device connectivity and battery charging can be added: iOS to 192kHz/24 bits and Android. Battery charging up to 2.4A, allowing iPad, iPhone and iPod to be charged to Apple's specifications.
Optional support for Apple's authentication protocols.
Optional Android support for Samsung's Galaxy devices.
Simple Interface requirements: Power (+5V), Audio (I2S), Control (SPI).
Module can be Galvanically Isolated (power, data, and control) from rest of system.
Designed to be software upgradable - from system microcontroller over SPI.
