    Hi, Robert,

    The TAS5538 is still in development. Actually, we are working on a new and improved version, TAS5558.

    Did you purchase an EVM using the TAS5538?

    Robert,

    OK, great!

    Keep your eye out for TAS5548, we should have it out around Thanksgiving (end of Nov for you non-Americans), followed by TAS5558 about a month later.

    Hi Don,

    I bought a tas5624 "husky" evm recently and I'm having trouble.

    - The documentation says a tas5558 is fitted but I have a 5538. Register 0x02=3. And it says 5538 on the package. 

    - the input board usb-3 doesn't work with the three pc's I have access too. All are windows 8 or 8.1. There is no i2c action at all. I have hooked an fpga board to the i2c bus and have good  now. 

    - evm  guide says write 0x03=0, write 0x12=0, write 32bit volume to 0xd9 and it should spring to life. Nada. 

    - confirmed all i2s signals are good and clean from both the USB board and also from a Wolfson wm8731 I lashed up for test.

    - tried 44.1k and 48k, 11.28mhz mclk (256fs), 2.8mhz sclk. 

    - valid signal is low. At times the Wolfson chip works for a few seconds at best.

    - The error register gives me nothing. .. Just 0 and occasionally 2 and that is documented as internal faults. 

    There is contradictory information about the mclk required too. Some sections of the 5558 datasheet say it can synthesize a higher mclk from 64fs (sclk). I would really prefer this if possible. 

    I found a reference to a wireless subside design that had completely different i2c initialisation but even that doesn't work. Also I can't even find the usb board schematic.

    Help! 5538 errata sheet?
