I am desperatedly looking for SC6135B chip pinout numbering. There is no datasheet anywhere. The chip is mostly used for low end cd-players or car cd/radio players. May be some of you found the SC6135B chip in some device and have the schematic? Or have the SC6135B datasheet anyhow?...

May be there are some serious guys here?... Not just a google surfers

Thank you for the link. It is one of the first that google lists after SC6135B being put and of course I know it. If you would carefully look at the picture you could notice that the pin descriptions are unreadable. The picture resolution is too low.

Thank you for the links.
Especially the HF630BF and Sanyo MDX1100 are detailed and useful. Although they both do not contain the information I am looking for: numbering of I2S pins. To be more specific the SDOut, WS and BCK pins as on Silan's page here: BlockDiagram
The pins are not used in the above devices and there is no description of them on the schematics.
In the meantime I've found the schematic with similar Silan's chip: https://fccid.io/RQU-HF638BPT/Schematics/Circuit-Diagram-2293706 which is a small help for me. It incorporates I2S signals.
What I currently do is working on Tangent CD II player - see the picture attached. It has broken SPDiF output and I want to use the I2S signals from SC6135B applied and convert them to SPDiF in my own way. My plan for today is just look for the I2S signals on not connected pins of SC6135B with oscilloscope. I have a sharp needle for SMD on a probe. If I am succeed I will describe the rebuilt here. I feel I owe ElektroTanya a lot - the schematics here are quite often just lifesavers.

Thank you for another link from google listing. It is also useless but probably you have just noticed only the datasheet.pdf link and assumed you had found a gold. I know this link and it links you only to sign into the jotrin who is an electronic parts wholesaler. After creating an account (which I've made few days before starting this topic) it redirects you just to Silan - a producer of SC6135B. I asked a producer for a datasheet but had no reply.
