Chips & Tricks
Below is another representation of
the data flow :
ICS2115 ====> uDP6376 --+
|--> TL084 --> CS4231A --> Outputs
YMF262 ====> YAC512 --+
Of course, you need to know where the pins are located in order
to start playing with (analog or digital) signal routing. I'm
not going to present them with ASCII art, no way. Just putting
some links where I found the tech sheets, with the help of some
other people. Make sure to read (and understand) them !
That's all you need if you take the "Fast" or "Analog" options.
In fact you need some OP AMP to amplify the signals from both
DACs' outputs. I would suggest the
NE5532A (type 5532 in the search engine under tech docs
and get both the application notes and the datasheet) or the
The NE5532D is actually used on the Tropez as the final
amplification stage, i.e. right after the CS4231A.
ICS2115,the Wavefront Synth. Obviously, you need that one !
- µDP6376. Datasheet yet to be found.
- YMF262 is the FM synth. Yamaha finally included the datasheet
- YAC512 is a 2 Channel Floating DAC completing the YMF262. Goto
page, note the fax # and use the "find" utility of your browser to
locate the YAC (not the Bison ...).
TL084 is a quad Operational Amplifier. I believe it is
equivalent to the 084C actually used on the Tropez.
is the Multimedia Audio CODEC. You dont' strictly need this one,
but it helps understanding the way things were patched together.
CS8402A if you want to go the "Digital" way (and forget
about the OP AMPs above).
