    Hi ,

    This is my first post on this forum.
    I have realized a CI for the CD/DVD drive with a SPDIF output .
    Have a look at the three fotos .

    The CD on the foto is an ASUS CD 520 and the CI is a "low cost" version.
    7805 regulators .
    Standard oscillator,
    Standard capacitors.
    The 12v is connected on the CD connector .


    A best version would be :
    low noise regulator ( AUDIOCOM ....)
    TENT oscillator
    OSCON capacitors
    An independant 12 v


    A custom version ....
    You put what you want and what you have the CI is very large ....
    :)

    If you have any questions ...

    75 Ohms ?

    You have different solutions on the CI .

    The RS 422 drivers has TX+ and TX- outputs so you can have a differential link .
    You can put a resistor between TX+ and TX - ( on the CI ) .


    I use only the TX + with a resistor connected to the GND .
    :bigeyes:


    On my DAC i have the same RS 422 Drivers .The shema is the same than
    this circuit ,The TX + and TX - outputs are directly connected to the CS 8414
