24/192 AD Converter 1090 : It did not work with Focusrite Scarlette 18i20 3rd Gen and is a cheap designed

The price is expensive and should be cheaper than that. The one I bought could not get synced by Focusrite Scarlette 18i20 3rd Gen. 18i20 keep locking and unlocking as SPDIF input into the card. It just worked without syncing by 18i20.The SPL card also has no ADAT input and even has not real ADAT output for syncing just SPDIF and the ADAT optical output on the card is only Optical SPDIF type which made me confused, I thought Optical output is ADAT output but in reality on this card is only Optical SPDIF out version which is parallel to SPDIF out. The way the card designed is a cheap interface but the price is really high compare to the other audio interfaces that you can get for £60 or less and have all ADAT & SPDIF input/output as well as other ports. Finally I had to return it .
