Hi knee266-San,
Here's part of my designing TAS6422 amplifier schematic.(Not evaluate yet)
I guess SOP device is DS90LV048ATM, and TSSOP device might be a 74LV541A or something like that...

Be aware this modules are not a I2S extractor, they just adapt voltage and impedance LVDS <-> TTL
Hi CyberPit,
May I know, is there any limit on the use of this voltage level conversion?
ex: cannot connect to TV, NB or STB .......
thanks.

knee266-San,
This board is designed for DAC/Audio-Players which has LVDS-I2S Output. This format specification is just De-fact standard and it's different from Authorized HDMI(Such as Official Video products). If you want to connect with your DVD player, you need to buy a HDMI Splitter which have S/PDIF output and S/PDIF receiver for I2S output.

There are a few on aliexpress that will convert HDMI (normal) to I2S. Most are only 2 channel extractors and they require you to have your HDMI signals as LPCM in order for it to work. I was looking at a multichannel HDMI to I2S to send it to my computer for processing and bass management of my 5.2 channel setup.
Hi,
I am very interested in a HDMI-to-I2S Solution for Multichannel, top.
Thatswhy I looked for candidate Chips: my result: Chips from Lattice-Semi. E.g. The SIL9233A .
It offers 4 I2S lanes for max. 8 channels After the included DRM-Decoding. It is also widely available!
Altough it will exceed my skills, I think a DIY Integration should by feasable.
What are your thoughts in this?

Thank you! Do you know something concerning the availability?
In this terme the Lattice-Semi seem to be easier to be obtained by hobby driven people

Interesting device
I am very interested in this topic. Regarding audio only devices Lattice produces this one: SiI9437. It is compatible with eARC.
It would be great to have the full amount of channel in lossless quality. The component is cheap and seams to me easy to use, the fact is that the datasheed is under NDA and it is not available for download.
I did not find more information than the one provided by Lattice HDMI 2.1 eARC Transmitter/Receiver - Lattice Semiconductor.
Is there any chance that someone in this forum can obtain the datasheet?
I could develop one demoboard for this component 🙂
