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
