[sdiy] Re: SAD1024 different modes

[Scott Stites]

Hi Mike,

Do you have any insight as to why A/DA chose to mix all four outputs of the SAD1024/MN3010 into the circuit - higher level?  I mean, wouldn't mixing all four outputs together somewhat defeat the purpose of the parallel mux configuration?

Cheers,
Scott

JH and Scott,
Please excuse my  wording... what I meant was that both halves are driven
differentially.... and yes, they are operating with swapped clocks, in the
same manner that Reticon shows for parallel multiplex. Also pre-emph and
de-emp on the same board... there is no steep lowpass filter on the output
(!).

The original A/DA did use the SAD1024... later versions used the MN3010. I
had the schematics for the MN3010 version but not the original  version,
and wanted to build one so modified the circuit to use the Reticon chip.
Regards, Mike
