I have tried to find full specifications and application notes for the SA9227 USB to S/PDif but so far without any luck. I've even tried other search engines than Google! - does anybody know if it is available and if so where/how?
Any help would be greatly appreciated.
PS. The best I've been able to find i this one: http://download.esm-cn.com/ATTACHMENTS_201408_101635_20140829860_pdf/SA9227-v1.3a.pdf

Well, I'll ask also ))) Anybody know, how to connect an ADC PCM4222 to PC via USB, using SA9227 or either similar IC ?
I rather looking for official distributor or reseller . The purchase was in Europe will be ideally.
SA9227 has pins for connecting ADC by I2S bus -> ADDAT,ADSCLK,ADSYNC,ADMCLK or S/PDIF -> SPDRX.
S/PDIF or I2S input port must be enabled in SA9227 configuration.
Configuration of SA9227 is stored in external EEPROM.

Thank you for info JarekC,
As I understand, SA9227 connected to EEPROM by I2C bus. Is there any info about what to program to that external memory IC to get SA9227 working ?

It is a special tool for generating EEPROM firmware.
But it is avaliable only from Savi-Audio after signing NDA documents.
