Module HDMI extractor to I2S / Coax / Optics

HDMI A / V to I2S audio / Coaxial / Optical / HDMI - Compatible MHL

Extractor HDMI digital interface unit

This module is an HDMI extractor. It allows to recover the digital audio stream of a digital HDMI source (including MHL) towards a digital coax port / optical or HDMI (I2S via HDMI).

This interface will be particularly useful in complex home theater installations, where multiple sources are likely to successively vary between audio and video functions.

This type of module is ideal in that it separates the video and audio streams to convenience while maintaining appropriate audio formats for advanced facilities.

It has a function of ressampling to select between an output 2-channel / 5.1 channels or audio output corresponding to the input (bypass).

Explanation of the 3 selectable modes:
- TV: sends audio through HDMI to the TV, and does not extract audio on the SPDIF output
- AMP : extracts stereo audio (2 channels) to the audio outputs
- DOU: outputs 5.1-channel audio to the audio outputs

EP92A3E Chip

The function of extracting the audio signal to digital output is performed by an EP92A3E chip, complying with the HDMI 1.4 standard. This component is compatible with both single HDMI inputs and MHL 2.0 sources (HDMI to USB adapter typically used to connect a smartphone to an HDMI input).

The EP92A3E chip is capable of addressing different digital protocols, requiring several levels of signal accuracy. It has an HDMI repeater function, which also allows longer cables to be used to cover a greater distance. Its great compatibility with digital audio protocols makes it a very practical accessory to be prepared for any audio/video connectivity problem. It also provides the module with LPCM, HD audio & DSD Audio support. The Audio Soft mute approach is also supported.

Complete Connectivity

The connectivity of this interface is rich in possibilities since it offers the possibility to retrieve the digital audio stream via S/PDIF to a Toslink Optical connector as well as a Coaxial connector already mounted on the board. The I2S output via HDMI LVDS can also be used as a basic output via an HDMI connector already mounted on the PCB. Also two I2S / DSD outputs are available. One is connected to an XH 2.54mm 6-pin male connector; the second is in the form of solder pads.

The I2S LVDS via HDMI connectivity of this device uses the PSAudio format.

Résultats : flux DSD 2.8Mbits reconnu par mon DAC Teac UD701N depuis un lecteur blueray Sony UBP X500. Prévoir 2 alim 12V ( pour alimenter le module. Parfait

Flawless transaction
I wanted to capture the audio out from my AppleTV and send it to my DAC via i2s. This device helped me to achieve that goal. It required one extra hdmi cable in the signal as well as a second hdmi cable to handle the i2s duties. I also needed a 5V power supply that wasn’t included. I was shocked at how quickly the unit was delivered.

Great solution
The item is for me a great solution for hearing SACDs in stereo (mostly with headphones) directly from my Cambridge Audio 752 BD through the Holo Audio May without any conversion to PCM.
In the May you've to set the I2S to ALT2 and then it's working without any problems.

Marche bien mais on doit comprendre qu' on peut pas connecter HDMI Out avec son DAC si on voudrait utiliser I2S. À la place, on doit utiliser IIS Out. C'est aussi HDMI. Le nom est un peu trompeur. Pourquoi pas le qualifier I2S Out?
