Philips SAA775x

Started by stevenvh June 13, 2006
Hi,
anyone seen any relevant documents (i.c. datasheets, appnotes) on the
SAA775x (-51, -52, -53)? The only documents I can find are flyers. :-(
You'd think Philips would be more open if they want to sell their stuff.
Well, maybe they don't want to really...
TIA

Steven


Greetings,

A brief look on their website showed that SAA7751,2,3 are discontinued
products. That does of course  not explain the lack of datasheet, but
does indicate that you might whant to use something else.

Was it for a new product ?

OK, I must have overlooked the discontinuation notice. However, if you're refering to DN56 it only mentions the SAA7750 and -52, not the -51 and -53. It was(/is) for a new product, yes. I want to start working on a wireless audio server, and since Philips has(/had) a reference design around the SAA775x, I thought it would be a good starting point. Philips rep is pretty mute about it all :-( Other ideas are welcome. Thanks for your reply. Steven
I think the target market for these chips were "very high volume" MP3 
customers... where the required complex techinical support is comercially 
viable for Philips... in these volumes.

I recall SAA775x used a ARM7 core and audio hardware on-board.

These days Philips has LPC2000 series micro's like the LPC2138  in the "main 
stream" and there is general support to general customer requirements.

The only think you need to add - hardware wise is the  Audio DAC interface,

The Philips LPC2138 design contest -  has an entry using the LPC2138 and 
Audio codec.
